Figure 3. — Action potential firing rates evoked by depolarizing current injections vary by MSN subtype. A, Voltage response of male and female Drd1a and Drd2 MSN subtypes to a depolarizing post-rheobase current injection. B, Drd1a MSNs exhibited decreased action potential firing rates evoked by depolarizing current injections compared with Drd2 MSNs. C, The slope of the evoked action potential to depolarizing current injection curve (FI slope) differed by MSN subtype, with Drd2 MSNs exhibiting increased excitability compared with Drd1a MSNs. FI slope, Slope of the evoked action potential to depolarizing current injection curve. *p < 0.05, **p < 0.01, ****p < 0.0001.
