Figure 5. Four different discharge responses found in MCs.

The discharge responses were induced by sustained somatic current injections. Top, accommodating (AC) responses show gradual increase in interspike intervals, including classical (c-AC, regular firing onset; top left) and bursting (b-AC, burst firing onset; top right). Bottom left, classical non-accommodating (c-NAC) cells display virtually no change in inter-spike intervals with regular firing onset. Bottom right, burst irregular spiking (b-IS) cells display abrupt changes in inter-spike intervals during steady state and bursting onset.
