Other categories referring to Dual recording from pyramidal cell-basket cell pairs reveal unitary EPSPs in basket cells mediated by one and two synaptic junctions. The unitary EPSPs have fast rising time and short time duration. Closely timed (10-50 ms) pairs of presynaptic action potentials resulted in statistically significant paired-pulse depression. The reliability of transmission is high, but the fast time course of the EPSPs constrains their temporal summation. Due to the relatively small amplitude of unitary EPSPs several convergent inputs will therefore be required to elicit suprathreshold responses.
