Systems Neuroscience Info-Dump: Memory, emotion, and pain localization

Listen

Description

Okay, here's the info-dump I promised during episode 2. It just got kinda long, so I figured I'd make a bonus episode about it. Covers the topics of:

  1. Different rates of memory encoding in key brain structures
  2. (Theoretical) different motor pathways for emotionally driven vs. volitional movement
  3. Nerve trivia! What is the largest single nerve in your body and why we have poor pain localization in the torso area (particularly in our gut/viscera)

Content starts at 4:23.

Silly bonus-content theme song is at: 04:04 for those who wish for a dose of silly.

(For additional reading on emotional motor pathways, see the Gothard (2014) paper referenced below.)
