Figure 8. Effects of lesions on shock-induced changes to circadian rhythms.

Figure 8

(a) Mean number of pellets and (b) mean activity (distanced travelled in m) in the dark (filled bars) and light (open bars) phases of AMYX (n = 7), SCNX (n = 8), and sham (CON; n = 7) animals during the last 5 d of baseline (left), unsignaled nocturnal (center) and unsignaled diurnal shock (right; SCNX and CON only). Red highlights indicate shock period. Error bars represent SEM. (c) 24-h waveforms (outside) and raster plots (inside) of feeding (left) and activity (right) from amygdala-lesioned rats (n = 7; baseline and unsignaled shock conditions represented by black and red, respectively). (d) 24-h waveforms (outside) and raster plots (inside) of feeding (left) and activity (right) from SCN-lesioned animals (n = 8). Waveforms show the mean feeding and activity over 24 h (bold lines), in 10-min time-bins, of all animals in each group averaged over the last 5 d of each experimental condition. SEM is shown as the shaded areas above and below the bold lines.
