Figure 7. Potentiation affects basal release in synapsin (−) but not in synapsin(+) boutons, and it increases synaptic enhancement during a subsequent stimulation in synapsin(+) but not in synapsin (−) boutons.
A,B Synaptic activity recorded during a continuous stimulation at a 10 Hz frequency in potentiated (open circles) and naïve (solid squares) synapsin (+) (black) and synapsin (−) (red) boutons. Each data point represent the average of 100 subsequent responses.
C. Basal quantal release (recorded at a 3 Hz stimulation frequency) in potentiated and nonpotentiated boutons. Data collected from 22-30 preparations for each line at each condition.
