using intracellular recordings in identified PV+ FSIs in the striatum (Bracci et al., 2003; ventral striatum specifically: Taverna et al., 2007). In vitro studies of such striatal FSIs have revealed prominent subthreshold oscillations in the 50 Hz range. Importantly, these oscillations did not require fast synaptic input, but depended on the amount of membrane depolarization instead (Bracci et al., 2003), suggesting that they are generated by intrinsic membrane properties and not volume-conducted or the result of network properties.
