Prelimbic cortex recordings in freely-moving mice. a, Schematic depicting tetrode placement in the PL cortex and recording paradigm in the T maze. The yellow line indicates the point at which the mouse chooses to go left or right. b, Representative average waveforms and autocorrelograms of sorted units, likely representing the same putative neuron, across automated and manual methods; TT1_1, and so on, indicate tetrode channel numbers. The pink line represents the refractory period. c, Raster plots for single-units in panel b. Each row represents a trial in the T maze and each tick is a spike. Notice that the trials are aligned to the timepoint indicated by the yellow line (4 s), which corresponds to the moment that the mouse arrives at the intersection of the stem with the arms of the T maze in each trial (as in panel a)
