I found a video by @paulandersen showing how the ions flow down the axon and actually creates a wave of action potentials down the length of the sheath. Even uses the same gif as part of it. Really cool.https://t.co/oxNWGicpuD https://t.co/eMKSNm2BaY

In my head I had this modeled intuitively as similar to how a waveform signal propagates down a coax cable. You can imagine that as a series of capacitors and induction coils chaining together. But getting to see the specifics of this ion gradient cascading is more useful.

Now to find out what occurs when we see acute osmotic demyelination (rapid sodium loss/gain) and how that feeds into this process given the sodium and potassium pumps doing things in other cells in the brain.

Seeing how important the electrolite bath is (he refers to it as the memory aid "a salty banana") makes me wonder: Is IBS causing me to not have as much of an action potential? Or is that compensated for somehow? https://t.co/dHn6EsgRtO

My Crohn's disease symptoms causes me to shit out all my sodium. So I constantly need to replenish my bile salts. This absorption process failing also means I struggle to absorb other electrolytes. Like Calcium, Magnesium, & Potassium.https://t.co/X00sK7nrtp

Uric acid keeps popping up on my radar the past few days. Maybe sodium butyrate and uric acid are involved somehow.https://t.co/3Ez8kYjKq5

How we define things matters: Weird diet meant to help with high blood pressure seems to impact Gout.But I'm just being salty again?"hypothesized that reducing sodium intake would lower UA levels""we found that higher sodium intake decreased serum UA"https://t.co/YV8uYShjr4

Worth noting coax doesn't have that directionality aspect that is a physical artifact of the way the channels are arranged along the axon. I also had this in my mental model, just never a concrete reason before today. Thanks @Rainmaker1973 & @paulandersenhttps://t.co/e72s1tX2Lj

Forming, unforming, reforming. the coding, decoding, and recoding of the assemblage. Continuously reforming gradients in the environment.Socialnet as filter. Shape as feedback loops. Directionality like neurons. A layered mealy machine powered by attention/recombinatory noise.

Also thank you @MMMalign for sending me stuff like this. I learn so much when people send me weird things like this random gif.
