Figure 8From: The internal state of medium spiny neurons varies in response to different input signalsDifferent steady states of the DARPP-32 system in response to a high- or a low- amplitude signal. Input signals are combinations of dopamine stimulation and Ca2+ influx. They are repetitive, transient with a time scale of milliseconds. Blue lines: Responses to a high amplitude signal; red lines: Responses to a low amplitude signal.Back to article page
