Olfactory bulb main mitral GLU cellDistal apical dendriteI Na,t.Implied by recording of fast prepotential. Dual patch recordings provide evidence for both backpropagating and forward-propagating impulses in the primary dendrite (Mori K et al, 1982 [turtle]2 ). Chen et al 1997).Dendritic patch recordings showed an even density of Na channels (120pSum-2) up to 350 um from the soma along the primary dendrite to theorigin of the glomerular tuft (Bischofberger J and Jonas P, 19973 ). By combining intracellular recordings and two-photon microscopy imaging of [Ca]i in rat it was shown that APs backpropagate at full amplitude up to the tuft (Debarbieux F et al, 20031 ).
Olfactory bulb main mitral GLU cellDistal basal dendriteI Na,t.Dual patch recordings and Ca2+ imaging of mitral cells in the ratolfactory bulb slice suggested that action potentials propagating intothe basal dendrites decrement approximately 20% per 100um (Margrie TW et al, 20014 ). Using Ca2+ imaging, full action potential invasionthroughout the length of the basal dendrites, suggesting the presence ofNa channels at somatic density, was observed by (Xiong W and Chen WR, 2002 [rat]5 ). By combining intracellular recordings and two-photon microscopy imaging of [Ca]i it was shown that AP propagate at full amplitude up to the most distal branches (Debarbieux F et al, 20031 ).

Dual patch recordings provide evidence for both backpropagating and forward-propagating impulses in the primary dendrite (Mori K et al, 1982 [turtle]2 ). Chen et al 1997). Dendritic patch recordings showed an even density of Na channels (120pS um-2) up to 350 um from the soma along the primary dendrite to the origin of the glomerular tuft (Bischofberger J and Jonas P, 19973 ).
