ASMR* : in terms of brain-networks, neurotransmitters, and endocrine response.
( I was reading up on motor neural voltages, between sleep and non-sleep states, and ended up at ASMR. )
Perhaps this is relevant to my preferred state of mind, as a generalist, whereby I allow myself all-dimensional reactions to stimuli.
ASMR apparently reflects a "higher than usual" synchrony between the CEN* and DMN*. The SN* is characteristically less-engaged, whereas it is usually responsible for flagging issues, and raising them into priorities, which then interruptively switches between CEN-dominance and DMN-dominance.
Generally : this appears to be a risk-off state ( see : dACC* ), where sensory inputs of ambiguous risk are not interpreted immediately as threats, but are instead allowed to be contemplated as amusements ( see : NAc, VTA* ). The states of threatened and amused, each involve separate neuroendocrinal cascades, which are available for further reading.
I reflect also on how interoception is often referred to as "subjective feelings" in the literature - whereas I find that subjective feelings may all be quantified in terms of concrete sensory data types.

- - Autonomous sensory meridian response
- - Central executive network ( motor task oriented )
- - Default-mode network ( internal imagination oriented )
- - Salient network
- - Dorsal anterior cingulate cortex
- - Nucleus accumbens
- - Ventral tegmental area ( mesolimbic and mesocortical pathways )
Yeah, one of the things putting me off neuro studies for so long was the word soup.
