Figure 6From: The internal state of medium spiny neurons varies in response to different input signalsDifferent responses of the DARPP-32 system to a one-shot or a repetitive signal. Input signals are combinations of a dopamine signal and Ca2+ influx. They have low amplitude and a sustained shape with a time scale of seconds. Blue lines: Responses to a one-shot signal; red lines: Responses to a repetitive signal.Back to article page
