Inactivating current
WebThe membrane current and the transistor signal are plotted in Figure 8. (The chips were cleaned with a mild dish detergent). Upon depolarization the membrane current exhibits an inactivating A-type potassium conductance and a non-inactivating K-type potassium conductance. The transistor response is quite different. WebAug 6, 2024 · Inactivating voltage-gated K + (Kv) currents were first characterized in neurons from the marine gastropod Onichidium verruculatum and were subsequently described as “A-type” ( Hagiwara et al., 1961; Nakajima, 1966; Connor and Stevens, 1971a, b; Neher, 1971 ).
