Afterpotentials associated with different granule cell layer neuron types. (A) Example responses to depolarizing current steps in three types of GCL neurons. Action potentials truncated. (B) Plot of afterpotential amplitude assayed 500 msec following step offset. Number of cells tested are indicated within each bar. Golgi cells did not generate an afterpotential to the standardized depolarizing test stimulus (mean amplitude 0.0 mV, n = 10 cells). (**) P < 0.002, (***) P < 0.0001.
