Supplementary Figure 2: Histological reconstruction of neural recording sites in the BLA and PL.
From: Amygdala inputs to prefrontal cortex guide behavior amid conflicting cues of reward and punishment
Related to Figures 2, 3, 4, and 5. (a-c) Electrodes were chronically implanted in both the BLA and PL for simultaneous single-unit recordings. Error bands for the representative waveforms represent s.d. Circles of matching colors in the coronal drawings correspond to the same animal. (d) Representative confocal images show the recording sites for one animal. (e) Representative waveforms and clusters from well-isolated cells. Waveforms are illustrated in a superimposed manner for each cluster. Clusters are shown in three-dimensional principal component space. (f-g) Distribution of firing frequencies for the BLA and PL cells. Red lines indicate the cutoffs used to exclude low firing rate cells (<0.1 Hz) from the cross-correlation analyses, as cells with such firing rates typically produce unpopulated correlograms with spurious peaks that may result on false positive correlations.
