The variability of neuronal firing across the cycle was altered by stress. The coefficient of neuronal firing (CV) was measured as an index of firing variability. (A) The overall CV of LAT neuron firing was not impacted by repeated stress (left). The CV was not significantly different between diestrus and proestrus in control rats or after repeated stress (right). (B) The cyclicity index for CV of LAT neurons was similar between control and stress groups. (C) The overall CV of BA neuron firing was not impacted by repeated stress (left). While CV of BA neurons was similar between proestrus and diestrus in control groups, after repeated stress the CV was significantly higher in proestrus compared to diestrus (right). (D) The cyclicity index for CV of BA neurons was increased by repeated stress. All data mean ± s.e.m. *p < 0.05 Holm-Sidak’s multiple comparisons test after 2-way ANOVA.
