Different physiological properties of spontaneous excitatory postsynaptic currents in nucleus accumbens shell neurons between adult and juvenile rats

► Amplitude and frequency of sEPSCs in NAcS decrease in adult than in juvenile rats. ► Half width and decay time of sEPSCs in NAcS increase in adult than in juvenile rats. ► Rise time of sEPSCs in NAc shell increases in adult rats than that in juvenile rats.
