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 …
Editorial: CNS pain circuits in health and disease – The perception of pain is gated by level of associated valence. Neurokinin-1 Receptor-Immunopositive Neurons in the Medullary Dorsal Horn Provide Collateral Axons to both the Thalamus and Parabrachial Nucleus in Rats – Tree walk, supporting the medulla as initiation point of salience. So, it looks like …
I’d planned awhile ago to spin up a wordpress site and publish primarily to that due to discomfort with Reddit’s content policies, but got distracted and lazy (honestly I didn’t really expect to still be looking into this by now). Is there any particular organizational style or content I should be focused on first? As …
