Stress and Sucrose Intake Modulate Neuronal Activity in the Anterior Hypothalamic Area in Rats - Fig 5

<p>One-hour dynamics of the firing rate (bin value in the line graphs, 1 s) of the cAHA neurons that significantly increased (CS-excited, red) or decreased (CS-inhibited, blue) their firing rate in response to the licking cluster start (CS) or were non-responsive to the CS (CS-nonresponsive, green) in non-stressful conditions (<i>A</i>) or immediately after foot shock stress (<i>C</i>). Spearman’s rank correlation coefficient (<i>r</i>) shows a strong correlation between the firing rate of CS-inhibited and that of CS-nonresponsive neurons in non-stressful conditions (r > 0.05, <i>A</i>) but such a correlation was not observed after stress (r < 0.05, <i>C</i>). The 1-h mean firing rate of the CS-excited (red), CS-nonresponsive (green), and CS-inhibited (blue) neurons was compared using the non-parametric Kruskal-Wallis test followed by a <i>post hoc</i> test in non-stressful conditions (B) and after foot shock stress (D). *Significantly (p < 0.05; Dunn’s multiple comparisons test) higher compared to all the other groups. ^#Significantly lower compared to all the other groups.
