Inhibition of spiking in a neuron with a high rate of spontaneous activity. The top trace shows spontaneous activity in the absence of a stimulus; the middle andbottom traces show the neuron’s response to 50 msec pure tones. The middle trace was recorded in voltage-clamp mode, the bottom trace in current-clamp mode. The resting potential of this neuron was −65 mV.
