MD increased spontaneous activity of LHb neurons. A-B, Pie charts with representative traces of A. voltage-Clamp (VC, V = 0) cell-attached recordings and B. current clamp (CC, I = 0) whole-cell recordings of spontaneous neuronal activity across non-MD and MD rats. Comparison of the percent distributions of silent (black), tonic (blue), or bursting (red) LHb neurons showed a significant increase in tonic and bursting LHb neuronal activity following MD. ***p < 0.0001.
