Figure 4From: The internal state of medium spiny neurons varies in response to different input signalsTypical responses of the DARPP-32 system to dopamine and glutamate (Ca2+ influx) signals. Panel A shows a typical response of the system to a sole dopamine signal, while panel B exhibits a representative response of the system to a sole glutamate (Ca2+ influx) signal. Panel C shows a common response of the system to a combination of dopamine and Ca2+ signals.Back to article page
