A protocol to investigate neural coupling of brain oscillations in rodents using in vivo electrophysiological...

Memory processes are highly dependent on a cross-talk between brain regions via synchronized neural oscillations. Here, we present a protocol to perform multi-site electrophysiological recordings in vivo in freely moving rodents to investigate functional connectivity across brain regions during memory processes. We describe steps for recording local field potentials (LFPs) during behavior, extracting LFP bands, and analyzing synchronized LFP activity across brain regions. This technique also provides the potential to simultaneously assess single unit activity using tetrodes. For complete details on the use and execution of this protocol, please refer to Wang et al.¹.
