Histological localization of electrodes targeting prelimbic cortex and higher-order thalamic nuclei. (A, Left) Example of electrode locations in prelimbic cortex (PL) in a coronal slice. The probes left a clear track in the tissue. (A, Right) Summary of prelimbic electrode locations (red circles) across all rats, projected into a coronal slice +3.00 mm anterior to Bregma. (B, Left) Example of electrode locations in the thalamus in a coronal slice. The tracks left by the probes can be easily observed. (B, Right) Summary of thalamic electrode locations across all rats, projected into a coronal slice −3.12 mm from Bregma. (C) Example of assignment of different shanks to different layers of prelimbic cortex. (D) Example of assignment of different shanks to different nuclei of dorsal thalamus. All slices were stained with the Nissl procedure. CL, central lateral thalamic nucleus; LDDM, laterodorsal thalamic nucleus, dorsomedial part; LDVL, laterodorsal thalamic nucleus, ventrolateral part; MDC, mediodorsal thalamic nucleus, central part; MDL, mediodorsal thalamic nucleus, lateral part; MDM, mediodorsal thalamic nucleus, medial part; Po, posterior thalamic nuclear group.
