Analysis of an LFP trace. a Schematic illustration of a multisite recording from a urethane-anesthetized mouse. A microdrive that held the electrode assembly, including 6–8 electrode wires, was inserted into the brain. b A representative LFP recording from the DG of a naïve mouse in vivo. Unfiltered and filtered (theta 4–10 Hz; slow γ 25–40 Hz; fast γ 65–140 Hz) LFP traces are shown from top to bottom. Band-pass filtering was performed only for displaying these traces (color figure online)
