Multisite Electrophysiology Recordings in Mice to Study Cross-Regional Communication During Anxiety

Curr Protoc Neurosci. 2017 Jul 5;80:8.40.1-8.40.21. doi: 10.1002/cpns.32.

Abstract

Recording neural activity in awake, freely moving mice is a powerful and flexible technique for dissecting the neural circuit mechanisms underlying pathological behavior. This unit describes protocols for designing a drive and recording single neurons and local field potentials during anxiety-related paradigms. We also include protocols for integrating pharmacologic and optogenetic means for circuit manipulations, which, when combined with electrophysiological recordings, demonstrate input-specific and cell-specific contributions to circuit-wide activity. We discuss the planning, execution, and troubleshooting of physiology experiments during anxiety-like behavior. © 2017 by John Wiley & Sons, Inc.
