Neurons from the greatly-enhanced and the moderately-enhanced trained groups did not significantly differ in their membrane properties and recording conditions.

Rise-time was measured for each detected event from baseline to peak. Decay time was measured for each detected event from peak to 1/3 the amplitude of the event.The current response was evoked at 0.16 Hz by 200 ms voltage step of −5 mV.RMS noise was measured from 750 ms period of baseline in which no miniature events were detected.
