Figure 2. K⁺ currents in an intact neurone in the slice and in its isolated ‘soma’.

K⁺ currents were recorded in a neurone before and after its isolation according to protocols given in Fig. 1. The isolation resulted in the formation of a ‘soma’ configuration. Na⁺ currents were activated by a voltage step to -30 mV after a 50 ms prepulse to -120 mV.
