Figure 6. Responses of neurones and their ‘somata’ to current injections.

A, voltage responses of an intact neurone in the slice and its isolated ‘soma’ to hyper- and depolarizing 10 ms command current pulses (I_C). The membrane potential in neurone and ‘soma’ was kept at -80 mV by injecting a steady-state current. B, V-I plots for an intact neurone in the slice and for its ‘soma’. The maximal deflection of membrane potential in either hyper- (•) or depolarizing direction (○) was plotted as a function of I_C.
