42. Matthias Stangl: grid cells in aging, path integration, and neural representations of actual physical movement in humans
Show Notes Chapter Markers

Matthias Stangl is a postdoc at UCLA, where he studies the neural representations of spatial navigation in social situations. In this conversation, we talk about his PhD work about aging, grid cells, and path integration, about his recent Nature paper, about the difference between movement in VR and actual physical movement, and much more.

BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith. New episodes every Friday. You can find the podcast on all podcasting platforms (e.g., Spotify, Apple/Google Podcasts, etc.).
