Modulating cortical responses to odor

Olfactory system function was studied using NeuroNexus Buzsaki32-CM32 probes for acute experiments in the mouse piriform cortex. Tal Dalal and Rafi Haddad of Bar-Ilan University recorded single units and LFPs across cortical layers in awake and anesthetized animals, as well as during periods of optical stimulation of the olfactory bulb to enhance gamma oscillations. The authors reported that multi-channel silicon probe recordings gave the same results as single tungsten electrode recordings. Their findings in Cell Reports reveal that granule cell – mitral/tufted cell interactions govern odor responses in cortex.
