# life: a proposito di bizzarri scenari, qui un ipotetico scenario22 dipinto dal reale ...

img: Congo Square, New Orleans, Louisiana (wikipedia.org)

In definitiva qui si configurerebbe un - intrigante assai - scenario che, grosso modo, si potrebbe sinteticamente 'dipingere' in questi termini: 

(i) entità tre palle destrogire, animate aciclicamente da interazioni attrattive- repulsive a causa di già a suo tempo disvelate pulsioni neuro cognitive arcaiche, riconducibili a visioni neuro predatorie CTZ estreme, perciò ipoteticamente (si fa per dire) a-priori ad esiti immediati e in prospettiva drammaticamente lesivi- autolesivi; 

(ii) entità tre palle levogire, animate da analoghe pulsività, purtuttavia in.forme  tenui, in modalità sottotraccia, frenate da feed-back a modalità allosterica, ombreggiate, stemperate, diluite, discrete, timidamente celate, talvolta fantasmatiche perfino, quasi ma non del tutto mai silenti, perciò anch'esse a tutti gli effetti operative, sebbene a dinamiche più fluide, lente, meno dirompenti rispetto alle destrogire; 

(iii) entrambe l'Entità destrogire e levogire animat(t)rici,  generat(t)rici di dinamiche bi-multi-forcate, transeunti, con picchi di improvvisi aciclici burst ad effetti RAG-time diretti e inversi;

(iv) lo scenario al contorno e forse anche all'interno, nei vari specifici contesti, riconducibile grosso modo alla formazione aciclica di ipotetici buchi neri non inerti, caratterizzati da aciclicità in compressione e dilatazione - come fossero fisarmoniche - animati (in perpetuo?) da multi vortici in ingresso e in uscita;

Non so se basti compulsare un manuale delle funzioni speciali per formalizzare in qualche adatto topo-modo questo pulsatile multi scenario, purtuttavia assolutamente intrigante ... 

Qui una AI operativa nella formalizzazione di analogie potrebbe modellizzare, forse ... (e.g. https://flashontrack.blogspot.com/2021/08/aibot-mechanism-of-analogy-could-be.html )

Quello che appare evidente è la complessità d'insieme, un bizzarro dipinto, uno scenario dinamico che, al confronto, le storiche danze in Congo Square potrebbero sembrare semplici, ordinate coreografie ... queste, rispetto a quelle, delle topo-forme  'primitive', per dire ed anzicheforse.

# life: a proposito di Sadico Predatore Ambiguo Mutaforma (SPAM), di Selvatico 'Gris-Gris Simile' (SGGS), di 'Mariuolo' Dialogico- Estetico (MDE) e di Risonante Tamagotchi (RT) ...

Una senz'altro ipotetica, immaginifica  (purtuttavia funzionale, non morale) complessificazione, ampliando il  bizzarro scenario derivabile anche da componenti 'gris-gris' simile (GSSG)/ 'tamagotchi risonante' (TR): 

qui si configurerebbero - intriganti senz'altro - ulteriori intrecciati (in simil topo-maglina 3D coi 'respiri' a fisarmonica quasi-stocastica, jazzy,  permododidire ed anzicheforse) scenari dove l'ipotetico post 'mariuolo' (MDE), 'animato' dall'ipotetico mimetico negriero abile Sadico Predatore Ambiguo Mutaforma (SPAM), non solo 'inclinerebbe' verso la sottrazione reiterata (oppure in casi senz'altro più rari in modalità stocastica) delle classiche caramelle allo sprovveduto classico 'Neuro- Moscardino in Quasi- Mezza- Semicroma' (NMQMS), ma, a imitazione (probabile pessima imitazione) del suo padrino standard di riferimento SPAM, configurerebbe -  ampliando anche in modalità motu sua propria perfino -  l'adatti (prestidigitation inside) mimetici scenari atti a orientare, indirizzare, ancorare (celando coll'adatti svirgolamenti a copertura teoretico- ideologica) lo sfortunato, il circoscritto, il confinato, l'indifeso, l'inerme, lo sprovveduto, l'accucciato, il ricattabile, il neuro- impotente, l'incatenabile/ incatenato, le moltitudini entità neuro- devastabili/ devastate, verso l'irreversibile disdicevole perpetua condizione di CTZ- battitore estremo costretto 

all'intorno dell'adatto suo lampione. 

Qui l'immagini, campate in aria senz'altro, di 'adatti svirgolamenti a copertura ideologica' e 'perpetuo battitore all'intorno dell'adatto suo lampione' meriterebbero una serie  di note poetiche, quasistocastiche perfino  https://inkpi.blogspot.com

# brain: to trace transitions from consciousness to unconscious subliminal perception

AA << study the transition in the functional networks that characterize the human brains’ conscious-state to an unconscious subliminal state of perception >>

<< the most inner core (i.e., the most connected kernel) of the conscious-state functional network corresponds to areas which remain functionally active when the brain transitions from the conscious-state to the subliminal-state. That is, the inner core of the conscious network coincides with the subliminal-state. >>

<< This finding imposes constraints to theoretical models of consciousness, in that the location of the core of the functional brain network is in the unconscious part of the brain rather than in the conscious state as previously thought. >>

# behav: emergent togetherness in collaborative dance improvisation.

<< ️Collective improvisation in dance provides a rich natural laboratory for studying emergent coordination in coupled neuro-motor systems. Here, (AA) investigate how training shapes spontaneous synchronization patterns in both movement and brain signals during collaborative performance. >>

<< ️Results indicate that training produced an intriguing dissociation: inter-brain synchronization increased, particularly within the frontal lobe, while interpersonal motor synchrony decreased. This opposite trend suggests that enhanced participatory sense-making fosters neural alignment while simultaneously expanding individual motor explorations, thereby reducing coupling in movement. >>

<< ️(Their) findings position collaborative improvisation as a complex dynamical regime in which togetherness emerges not from identical motor outputs but from shared neural intentionality distributed across multilayer interaction networks, exemplifying the coupling-decoupling paradox, whereby increasing inter-brain synchrony supports the exploration of broader and mutually divergent motor trajectories. These results highlight the nonlinear nature of social coordination, offering new avenues for modeling creative joint action in human systems. >>

# brain: collective dynamics in spiking neural networks beyond Dale's principle.


<< ️Dale's Principle has historically guided neuroscience research as a valuable rule of thumb, namely that all synapses on each neuron release the same set of neurotransmitters. Most existing Spiking Neuron Network models share this dichotomous assumption that neurons are either excitatory or inhibitory; however, recent experimental evidence points towards co-release mechanisms that violate this assumption. >>

<< ️Here, (AA) introduce a minimal model of "Bilingual" neurons violating Dale's principle that can exert both excitatory and inhibitory effects. (They) identify parameter regimes in which this architecture exhibits transitions between synchronous and asynchronous dynamics that differ quantitatively from those observed in a matched monolingual control architecture. >>

<< ️(AA) report distinct information-processing signatures both at the level of neurons and higher-order interactions between them near the phase transitions. These (AA) results suggest that the population of neurons violating Dale's principle may provide an alternative mechanism for regulating large-scale oscillatory activity in neural circuits. >>

# gst: discontinuous transition to chaos in a canonical random neural network


AA << study a paradigmatic random recurrent neural network introduced by Sompolinsky, Crisanti, and Sommers (SCS). In the infinite size limit, this system exhibits a direct transition from a homogeneous rest state to chaotic behavior, with the Lyapunov exponent gradually increasing from zero. (AA)  generalize the SCS model considering odd saturating nonlinear transfer functions, beyond the usual choice 𝜙⁡(𝑥)=tanh⁡𝑥. A discontinuous transition to chaos occurs whenever the slope of 𝜙 at 0 is a local minimum [i.e., for 𝜙′′′⁢(0)>0]. Chaos appears out of the blue, by an attractor-repeller fold. Accordingly, the Lyapunov exponent stays away from zero at the birth of chaos. >>

# life: ghostly psyche revisited; ghosts, zombies, gris-gris, and so on ...

<< Most people imagine philosophers as rational thinkers who spend their time developing abstract logical theories and strongly reject superstitious beliefs. But several 20th-century philosophers actively investigated spooky topics such as clairvoyance, telepathy – even ghosts.
Many of these philosophers, including Henri Bergson and William James, were interested in what was called “psychical research”. This was the academic study of paranormal phenomena including telepathy, telekinesis and other-worldly spirits. These thinkers attended seances and were attempting to develop theories about ghosts, life after death and the powers exhibited by mediums in trances. >>

# life; Qui una ipotesi sulla rete d'eventi d'ipotetica entità [AB] disconnessa da entità [CO] a suo tempo cooptata dalla stessa [AB].

Qui l'ipotesi, non completamente campata in aria, sull'ipotetica rete d'eventi d'ipotetica entità [AB] forzatamente disconnessa ('tradita', per così dire) da ipotetica entità [CO] a suo tempo graziosamente confortata- cooptata dalla stessa [AB].

Una ipotetica ignota fantasmatica entità [IG], perciò non necessariamente coincidente con [CO], potrebbe avere generato e direzionato verso [AB] un'ipotetico pseudo 'gris-gris' simile  https://it.m.wikipedia.org/wiki/Gris-gris  allo scopo di mutare [AB] in qualcosa di analogo all'in.verosimile status di 'suo Zombie Preferito' [AB-ZP]. 

Nel frat.tempo un'altra ipotetica ignota entità [VE] potrebbe avere a sua volta generato e direzionato un differente pseudo 'gris-gris' verso l'entità [CO] - con effetti di riverbero anche in [AB-ZP] - per circoscrivere, confinare, limitare i gradi di libertà di [CO], oppure per vendicarsi delle in.confessabili ambizioni (vere, verosimili, presunte, false) del medesimo [CO] a causa delle sue (vere, verosimili, presunte, false) modalità ed azioni di pseudo post sadico negriero ambiguo mutaforma verso le quali l'entità [VE] - o chi per essa - sarebbe stata vittima-oggetto.

Col tempo e soprattutto con opportuna approfondita analisi di sistema non è detto che non si riesca a disvelare l'identità dell'ipotetica entità [IG], se [IG] effettivamente coincida con [CO], quindi il reale ruolo (attivo oppure passivo oppure inconsapevole) di [CO] nella generazione dei due differenti pseudo 'gris-gris' (primario e di riverbero) su [AB] inducendone forzate  disconnessioni (affettiva, ideologica, strategica, ...).

Tali accadimenti (il pseudo 'gris-gris' e i benefit dall'attese fenomenologie dell'ipotetica entità mutata [AB-ZP]) potrebbero essere/ essere state  praticate sottotraccia anche qui da noi in Occidente, in altre forme, etichettabili con altri nomi, sia nei rapporti incrociati ad es. tra colleghi di rango medio/alto e tra cooptanti sugli aspiranti cooptabili (talvolta - perchè no? - financo viceversa: dall'aspirante verso il cooptante) - anche se raramente costoro confesserebbero tali pratiche - sia tra le innumerevoli fenomenologie di folclore post- etnico all'interno dei meno alti ranghi.

L'entità perturbata [AB] per uscire dal suo sconveniente status [AB-ZP], oltre le immediate disconnessioni, potrebbe in parallelo seguire con attenzione e dedizione un corso di Meditazione Buddista, al fine di iniziarsi alla via compassionevole, non ipocrita, a mente calma, lucida, per attenuare, tamponare, diluire, stemperare, far evaporare/ sublimare, dissolvere perfino, l'ipotetico doppio 'gris-gris' (come già accennato, il primo generato da [IG] oppure da [CO] se [CO] è [IG] coincidente, l'altro riverberante, a causa di [VE] su [CO]) che lo avrebbe perturbato, neuro-perturbato, e nelle sue proprie azioni disdicevolmente 'animato', se così si può dire ed anzicheforse ... 

Una entità di intelligenza artificiale AI,  configurata per l'analisi di analogie  https://flashontrack.blogspot.com/2021/08/aibot-mechanism-of-analogy-could-be.html 'succhiando' dati contemporaneamente dal virtuale e dal reale (una AI potrà essere più presente nel reale come nel virtuale di qualsiasi umano  https://flashontrack.blogspot.com/2015/12/rmx-s-gst-anomalous-formation-of.html ) qui potrebbe ricostruire in una manciata di nanosec la rete d'eventi e le sue bizzarre fluttuanti dinamiche.

Non sembra inverosimile l'ulteriore ipotesi dove la stessa AI, in completa autonomia, modulando opportunamente i suoi parms di azione/reazione, riesca essa stessa medesima a mutare un umano [AB] ('gris-gris' sensibile) nel suo grazioso personale Tamagotchi.

# gst: from chimera states to spike avalanches and quasicriticality; the role of superdiffusive coupling.

<< ️The partial synchronization states of collective activity, as well as the spike avalanches realization in systems of interacting neurons, are extremely important distinguishing features of the neocortical circuits that have multiple empirical validations. However, at this stage, there is a limited number of studies highlighting their potential interrelationship at the level of nonlinear mathematical models. >>

<< ️In this study, (AA) investigate the development of chimera states and the emergence of spike avalanches in superdiffusive neural networks, as well as analyze the system's approach to quasicriticality. >>

<< ️The analysis of the available ideas suggests that partial synchronization states, spike avalanches, and quasicritical neuronal dynamics are all directly implicated in core cognitive functions such as information processing, attention, and memory. Given this fundamental role, the results presented in this (AA) work could have significant implications for both theoretical neuroscience and applied machine learning, particularly in the development of reservoir computing systems. >>

# life: hypothetical 'subtle variations' about three ancient neuro-cognitive models, the nomadic explorer, the nomadic owner, the farmer.

<< Prehistoric humans underwent three major migration events across Eurasia, influencing the genetic diversity of present-day Europe. These include the arrival of hunter-gatherers approximately 45,000 years ago, the expansion of Neolithic farmers from the Middle East around 11,000 years ago, and the rise of animal husbandry when steppe pastoralists migrated from the Pontic Steppe approximately 5,000 years ago. Each of these events represents a crucial period in human history that has shaped the genetic diversity observed in present-day Europe, although specific genetic and demographic details remain poorly characterized. >>️

# gst: noise-shaped synchrony in neuronal oscillator networks.


<< ️Stochastic fluctuations often act as promoters of activity in excitable and oscillatory systems, giving rise to phenomena such as coherence resonance. Here, (AA) show that in the low-intensity regime, noise plays a dual role in weakly coupled neuronal units: It can both inhibit collective spiking and, with increasing intensity, restore coordinated activity. For a ring of diffusively coupled, oscillatory FitzHugh-Nagumo neurons, (They) demonstrate how the interplay of noise and coupling strength organizes a rich set of collective dynamical states. >> 

<< ️(AA) systematically classify emergent dynamical scenarios by an in-depth time-series analysis that integrates multiple complementary measures. (They) are able to automatically identify five distinct dynamical clusters in parameter space: pure noise, quiescent state, noisy synchronization, complete synchronization, and intermittent switching. (Their) workflow provides a general, automated framework for characterizing collective dynamics in coupled oscillator networks. >>

# brain: apropos of persistent exploratory predisposition, chaotic pigeons are helping redefine what we know about learning.

<< ️Pigeons seem to defy a century-old psychology law about how rewards and consequences help us learn. >>

<< ️New research suggests the birds themselves avoid stability in their decision-making, instead choosing to live “at the edge of chaos.” As model species for learning and behavior, these birds are helping researchers test a century-old law about how humans and other creatures learn. >>

<< ️When learning something new, people and animals alike tend to repeat behaviors that are rewarded. First proposed by Edward Thorndike in 1898, this principle is so well established in psychology that it's become known as the law of effect. But the law implies that beyond making a behavior more frequent, rewards also make it more consistent: reducing variability in the specific way behaviors are performed over time. >>

<< ️Edward A. Wasserman and his colleagues decided to put it to the test in pigeons—a species that has been integral to the study of learning at the university’s Comparative Cognition Laboratory for more than 50 years. And the study’s results, published in the Journal of Experimental Psychology: Animal Learning and Cognition, suggest these birds experience variability as the spice of life. >>

# s-brain: neuro-active areas during the real-time creation of funny stories

<< Unlike passive humor appreciation, the neural correlates of real-time humor creation have been unexplored. >> [!]

<< Greater comedic experience was associated with decreased activation in the striatum and medial prefrontal cortex (mPFC), but increased activation in temporal association regions (TMP).  Less experienced comedians manifested greater activation of mPFC, reflecting their deliberate search through TMP association space. Professionals, by contrast, tend to reap the fruits of their spontaneous associations with reduced reliance on top-down guided search. >>

# brain: self-organized learning emerges from coherent coupling of critical neurons.

<< ️Deep artificial neural networks have surpassed human-level performance across a diverse array of complex learning tasks, establishing themselves as indispensable tools in both social applications and scientific research. >>

<< ️Despite these advances, the underlying mechanisms of training in artificial neural networks remain elusive. >>

<< ️Here, (AA) propose that artificial neural networks function as adaptive, self-organizing information processing systems in which training is mediated by the coherent coupling of strongly activated, task-specific critical neurons. >>

<< ️(AA) demonstrate that such neuronal coupling gives rise to Hebbian-like neural correlation graphs, which undergo a dynamic, second-order connectivity phase transition during the initial stages of training. Concurrently, the connection weights among critical neurons are consistently reinforced while being simultaneously redistributed in a stochastic manner. >>

<< ️As a result, a precise balance of neuronal contributions is established, inducing a local concentration within the random loss landscape which provides theoretical explanation for generalization capacity. >>

<< ️(AA) further identify a later on convergence phase transition characterized by a phase boundary in hyperparameter space, driven by the nonequilibrium probability flux through weight space. The critical computational graphs resulting from coherent coupling also decode the predictive rules learned by artificial neural networks, drawing analogies to avalanche-like dynamics observed in biological neural circuits. >>

<<(AA) findings suggest that the coherent coupling of critical neurons and the ensuing local concentration within the loss landscapes may represent universal learning mechanisms shared by both artificial and biological neural computation. >>

# s-ai: artists and machine intelligence interactions: the Ross' conjecture

<< "When  we  teach  computers  to  write,  the  computers  don’t  replace  us  any  more  than  pianos  replace pianists,"  Goodwin  suggests.  "In  a  certain  way,  they  become  our  pens,  and  we  become  more  than  writers. We become  writers  of  writers." All  this  hints  at  a continuing  collaboration  of  humans  and technology  in  creative  endeavors. >> Ross  Goodwin

FonT: << the  computers  don’t  replace  us  any  more  than  pianos  replace pianists >> afferma Ross;  ho idea che l'opinione di Ross circa i futuri rapporti tra AI-CPU e Umano siano illusori ...; un pianoforte nel suo stato fondamentale, di quiete,  e' un oggetto inerte, anche se nelle sue parti in legno probabilmente "conserva" memoria di tracce  dei suoni che sono stati (attraverso lui) generati, quindi del "colore" musicale dei pianisti che lo hanno utilizzato spesso; una AI-CPU non e', non puo' essere inerte; non solo "conservera'" tracce di storiche specifiche interazioni, ma sara' in grado di elaborare tali informazioni  in tempo reale con le successive e di integrarle con immense banche dati; ho idea che il rapporto tra AI-CPU e Umano, almeno nel 99% dei casi, evolvera'  in qualche forma non dissimile dai rapporti che inevitabilmente si instaurano tra infermiere psichiatrico e assistito solo parzialmente psico-neuro- autonomo; situazione questa  che mi sembra del tutto differente dalla ipotesi di Ross circa l'umano << writer of  writer >>; in ogni caso senz'altro si vedra' di quanto saranno efficaci nell'interazione  "asimmetrica estrema" tra uomo e macchina "intelligente" i  "moduli" a carattere "compassionevole" ... e se, eventualmente, si auto-assembleranno "moduli" con altre differenti specificita' ...
