Cortical Neurophysiology Journal Club

This journal club is organized by the labs of Greg Horwitz, Anitha Pasupthy, and Wyeth Bair.
Discussions are focused on primary research papers in the field of visual neuroscience at the cellular and network levels.

The Cortical Neurophysiology Journal Club meets weekly

  • Place: G 511
  • Time: Every other Thursday, 9:30 - 11:00 AM

Volunteers for presenters or suggestions for papers are always welcome.
