MSPS and EA treatment alter VTA DA neuron responses. (A) Representative average extracellular neuron waveforms. The width of an action potential (AP) was measured from the start of that potential to the apex of the negative trough, and similar normal distributions of AP widths (range: 1.1–2.7 ms) were detected in PTSD rats, SEA rats, EA rats, and controls. (B–D) Average firing rates and bursting activity (%SIB) of VTA DA neurons in the indicated treatment groups.
