Burst-spiking nonpyramidal (BSNP) cells and regular-spiking nonpyramidal (RSNP) cells affected by application of NA or FNE. A, Voltage responses of a BSNP cell immunoreactive for CCK. Four action potentials on an all-or-none slow depolarizing potential were induced by a depolarizing current pulse from a hyperpolarized potential (−85 mV) caused by the bias current (A₃). Resting potential, −60 mV. This neuron was depolarized by NA (10 μm) application in a solution containing CNQX/APV. B, Voltage responses of an RSNP cell immunoreactive for CCK. Resting potential, −62 mV. This neuron was hyperpolarized followed by depolarization by FNE (30 μm) application in a solution containing CNQX/APV.
