Neocortex L2/3 pyramidal GLU cellDistal apical dendriteI Na,t.(Williams SR and Stuart GJ, 20001 ). Recordings from acute brain slices and in anesthetized rats using whole-cell recordings and Ca2+ imaging found that backpropagation of action potentials into the dendritic arbor is actively supported by Na+ channels both in vitro and in vivo. (Waters J et al, 20032 ).
