Figure 4. Fear-induced learning employing leg movement as the operant conditioning paradigm.

Figure 4

(A) Raster plots and PSTHs of leg movement transiently increased during the CS+ (UFM) and decreased following CS+ offset, whereas (B) the CS− (DFM) did not influence the frequency of leg movement. FM direction is indicated by arrow. Box plots of leg flexion events analyzed in 5 animals (C) showing a significant difference in leg flexion between the CS+ and CS−. Solid lines in boxes are medians, boxes surround 50% data and whiskers are 5th and 95th percentiles.
