Fig. 7: Comparison of CSD laminar patterns among cortical areas, monkeys and studies.
From: A ubiquitous spectrolaminar motif of local field potential power across the primate cortex

a,b, Mean CSD maps across probes from each area and monkey in study 1 (a) and study 2 (b). Current sinks are negative (blue), and sources are positive (yellow). The CSD values of each probe were normalized by the peak negative value. Laminar position 0 (y axis) is the position of the first identifiable current sink.
