Neocortex L5/6 pyramidal GLU cellSomaI K,Ca.Dual patch-clamp recordings showed that Ca-activated K+ (BK) channels were not triggered by neuronal action potentials in normal slices and only opened as neuronal responses deteriorated (smaller or absent spikes) and in a spike-independent manner, suggesting that BK channels may activate only in pathological conditions (Kang J et al, 2000 [rat]1 ). Intracellular recordings from sensorimotor cortex suggested that what activate IKCa persistently would not be calcium but some biochemical modification triggered by NMDA receptor activation (Kitagawa H et al, 2000 [cat]2 ). Ca2+-activated K+ currents were studied using whole-cell patch-clamp recordings from freshly dissociated mouse neocortical pyramidal neurons (Sun X et al, 20033 ).
