# s-brain-ai-data-tool: abstract versus concrete behaviors: a hierarchically ordered connectome

a model <<  to show how the physical brain could give rise to abstract thought >>

the <<  work demonstrates (..) the basic operational paradigm of cognition, but shows that all cognitive behaviors exist on a hierarchy, starting with the most tangible behaviors such as finger tapping or pain, then to consciousness and extending to the most abstract thoughts and activities such as naming. This hierarchy of abstraction is related to the connectome structure of the whole human brain >>

Another outcome of the research <<  will be a new geometric data-science tool, which is likely to find widespread use in other fields where massive data is difficult to view coherently due to data overlap >>

rmx-s-brain: working like a radio, deep inside and in the "zona incerta"

<< (...) central thalamus works like a radio dial that tunes the brain to different states of activity and arousal >>

<< Located deep inside the brain the thalamus acts as a relay station sending neural signals from the body to the cortex >>

<< High frequency stimulation of 40 or 100 pulses per second [ flashed laser pulses ]    woke rats. In contrast, low frequency stimulation of 10 pulses per second sent rats into a state reminiscent of absence seizures that caused them to stiffen and stare before returning to sleep >>

<< Damage to neurons in the central part of the thalamus may lead to problems with sleep, attention, and memory >>
