Figure 2. — Excitatory drive is decreased in aged DH neurons. (a) Traces show continuous recordings of spontaneous excitatory postsynaptic currents (sEPSC) from DH neurons in young (upper blue) and aged (lower red) animals. Lower overlaid traces are captured sEPSCs from young and aged recordings highlighting the amplitude range and time course of events recorded from young and aged animals. (b) Group data plots compare sEPSC properties in young and aged recordings. sEPSC amplitude was significantly decreased in aged recordings, whereas rise time decay time constant and frequency were similar in both samples.
