# 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. >>

<< The k-core of the conscious state is reduced to three active regions of the brain, the fusiform gyrus (left and right) and the precentral gyrus. These regions are the only active in the subliminal state. >>

# 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. >>

# 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' ...

# s-brain: silent synapses
<< (..) researchers were able for the first time to view the release and re-uptake of dopamine — a neurotransmitter involved in motor learning, habit formation, and reward-seeking behavior — in individual synapses. When all the neurons were electrically stimulated in a sample of brain tissue, the researchers expected all the synapses to release dopamine. Instead, they found that less than 20 percent of dopaminergic synapses were active following a pulse of electricity. >>

A new << (..) research confirmed what savvy marketers already know: the longer you look at one of two objects, the more likely you’ll choose that object even if you initially valued the other one more >>
<< (..) dorsomedial prefrontal cortex (PFC) plays a critical role in mediating the balance between prior value assessment and an object’s immediate appeal >>
<< The significance of the dorsomedial PFC came as a surprise because of its relative neglect in the decision neuroscience literature >>
<< Much work on value-based decision-making has focussed rather on the ventral-frontal and orbitofrontal cortex >>
This << findings suggest that, in the healthy brain, the dorsomedial PFC is also important in decision-making, helping to recall the value of objects that are not directly in view so that you can keep your options open >>
<< We’re trying to decompose the different aspects of decision-making. People have this idea that their preferences and value judgments are consistent and rational but, in fact, we’re heavily influenced by factors that are not apparent to us >>
