Effect of varying parameters on the delay between the arrival of an excitatory synaptic input pulse to an I-cell and the resulting spike of the I-cell.
A: Increase in
resulting from a reduction in drive density to the I-cell from
to
. The dashed vertical line indicates the pulse strength
below which the pulse fails to elicit a spike when external drive density to the I-cell is
. B: Increase
in
resulting from reducing pulse strength by 30%, from
to
. The external drive to the I-cell is fixed at zero in panel B. The dashed vertical line indicates the value of
below which the pulse of strength
fails to elicit a spike.
