Popular models of how “memory” works makes as much sense to me as most theodicies. Even with constructs like engrams, where we assume that certain configuration of electrical pulses get magically integrated into something coherent somewhere else in the network is really incoherent in the face of the evidence. “Memory” is a consistent and necessary

The traditional model of senses usually splits them up between five to seven distinct units, sometimes segregated by receptor, sometimes segregated by perception. Thinking about how to generalize these out in a consistent way, I think it might be more accurate to think about them in terms of Mechanical Waves, e.g. touch and sound, chemical

Finally have the website software up, so my goal is to start migrating appropriate content there (https://www.remodeledbrain.com) as time permits. Sub will be remain up, and I’ll probably continue using it as a scratchpad, but in order for it to remain useful I don’t want it devolving into every other neuro related sub if it

Salience provides the impulse, analogous to “flight/fight/freeze”. Valence tuning provides the behavior, “Run there”, “Yell”, “Play Dead”. Valence can modify the salience pulse, e.g. “freeze” can be modified to “fight” with high enough metabolic output through “positive” valence channels. Valence and salience combinations can produce unstable/highly error prone combinations which are “felt”, e.g. anxiety. For

Are dopamine, serotonin, etc “training” chemicals that help establish pathways rather than active signalling chemicals? Specifically, they work like something closer to “traffic lights” while peptide binding to astrocytes determine the actual “information” being transmitted. This indicates that the integrative process is mostly a reconfiguration of peptides integrated upward. Mechanically, this provides an actual non-magical
