Spontaneous firing of ventral tegmental area (VTA) group-2 neurons in lean and obese mice. (A₁) Spontaneous firing in lean mice. Scale bars, 100 pA; 0.5 sec. (A₂) Spontaneous firing in obese mice. Scale bars, 40 pA; 0.5 sec. (B₁) Interspike interval (ISI) histogram of lean mice. Bin width is 8 msec. (B₂) ISI histogram of obese mice. Bin width is 14 msec. (C₁) Average action potential (AP) current (n = 10) in lean mice. Scale bars, 100 pA; 1 msec. (C₂) Average AP current (n = 10) in obese mice. Scale bars, 40 pA; 1 msec. (D₁) Relationship between firing frequency (FF) and AP current duration in lean mice (n = 19). (D₂) Relationship between FF and AP current duration in obese mice (n = 8).
