Increased Accuracy to c-Fos-Positive Neuron Counting

Figure 5

Counts of the core label of c-Fos-positive neurons in the periaqueductal gray. Average number of the core label counted to control (Ctrl) groups and experimental (Exp) groups, using a threshold of 62% (inflection point) to background around the core label. The difference is significant on the Wilcoxon test.
