We use high-density silicon probes in the hippocampus and related circuits to record from single neurons and monitor the local field potential dynamics with high spatiotemporal resolution. When combined with optogenetics, we can “tag” neurons to achieve cell-type specific recordings as mice navigate a cue-rich treadmill while head-fixed or during restraint-free behavior. Optogenetics also enables us to study how specific cells within and outside of the hippocampus control important LFP dynamics, including theta and sharp-wave ripples. We use a variety of electrode layouts, including Neuropixel probes, to cover a range of research questions.

Jordan Farrell
Jordan is studying the role of the hypothalamus in executing exploratory locomotion and how activity is relayed to brain regions involved in spatial navigation. He is also interested in the networks underlying seizures and how the endocannabinoid system controls local neural activity and vascular physiology.
