Neuronal activity during task performance and histological verification of recording sites. a The photograph of a stained brain section showing the electrode track (top arrow) and the final location of the electrode tip (bottom arrow). All recording sites used were similarly verified to be in the prelimbic area (PrL) of the medial prefrontal cortex. In b rasters (top rows) and peri-stimulus time histograms (PSTHs, bottom traces) showed a neuron’s activities in A3k (left, red), VA3k (left, blue), A10k (right, red), and VA10k (right, blue) trials. Inserted is action potentials of this example mPFC neuron (2000 single waveforms and their average, black). Mean spike counts of correct trials were computed in 10-ms time windows and smoothed with a Gaussian (σ = 100 ms). Responses were aligned to the initial cue presentation. In multisensory trials, visual and auditory stimuli were presented simultaneously. Dashed lines denote the stimulus onset and offset. In the same way, c, d show two more example neurons
