donthatedontkillI don't understand what I'm feeling. Depression? Exhaustion? Heartbreak? Maybe even fear? Dissatisfaction? Something just isn't quite right. I'm not sure what to do about it because I don't know what it is. It's so subtle I can hardly hear it but it's constantly there. Been going on for days, I think even weeks. <a href="https://mastodon.social/tags/mentalhealth" class="mention hashtag" rel="nofollow noopener" target="_blank">#mentalhealth</a> <a href="https://mastodon.social/tags/depression" class="mention hashtag" rel="nofollow noopener" target="_blank">#depression</a> <a href="https://mastodon.social/tags/exhaustion" class="mention hashtag" rel="nofollow noopener" target="_blank">#exhaustion</a> <a href="https://mastodon.social/tags/love" class="mention hashtag" rel="nofollow noopener" target="_blank">#love</a> <a href="https://mastodon.social/tags/proprioception" class="mention hashtag" rel="nofollow noopener" target="_blank">#proprioception</a> <a href="https://mastodon.social/tags/alexithymia" class="mention hashtag" rel="nofollow noopener" target="_blank">#alexithymia</a> <a href="https://mastodon.social/tags/neurodivergent" class="mention hashtag" rel="nofollow noopener" target="_blank">#neurodivergent</a> <a href="https://mastodon.social/tags/actuallyautistic" class="mention hashtag" rel="nofollow noopener" target="_blank">#actuallyautistic</a> <a href="https://mastodon.social/tags/scared" class="mention hashtag" rel="nofollow noopener" target="_blank">#scared</a>

AngelaHonestly, I'd love to solely work out at home, but between parenting and <a href="https://mastodon.nz/tags/ADHD" class="mention hashtag" rel="nofollow noopener" target="_blank">#ADHD</a>, it's hard to organise my personal time and space.I also do better with body doubling, and my poor <a href="https://mastodon.nz/tags/proprioception" class="mention hashtag" rel="nofollow noopener" target="_blank">#proprioception</a> means I often need someone there in person to check and correct my form. It's the only way I managed to make progress back when I started doing yoga.

Albert CardonaWhen a GABAergic neuron synapses onto the axon of a sensory neuron, what happens?Turns out, in the proprioceptors of the locust leg (chordotonal somatosensory neurons), "All the available evidence indicates that the inputs that occur during walking are depolarizing, inhibitory, synaptic inputs."Depolarizing, inhibitory. How's that possible? Depolarizing because of where the resting potential of the axon is (which is different than the dendrite's), and the particularities of the GABA receptor on the receiving axons. Inhibitory because the depolarization is subthreshold, reducing the membrane voltage potential and, therefore, reducing neurotransmitter release when a spike arrives.What is this good for? Implementing an efference copy signal: "The rhythmic depolarization at different phases of the step cycle in different sensory neurons may represent a predictive action of the CNS when generating a motor pattern." That is, predicting when the proprioceptor will fire, and by how much, as a function of the self-induced motion. So this signal is subtracted in order to be able to measure (and react to appropriately) any unexpected signal (such as the leg skidding or hitting a rock).Wolf and Burrows, 1995.
