Figure 5From: The internal state of medium spiny neurons varies in response to different input signalsDifferent responses of the DARPP-32 system to a transient or a sustained signal. Input signals are repetitive, high-amplitude Ca2+ influxes (corresponding to glutamate stimulation) with a time scale of milliseconds. Blue lines: Responses to a transient signal; red lines: Responses to a sustained signal.Back to article page
