🧠 New preprint by Lee et al.: Fast dendritic excitations primarily mediate #backpropagation in #CA1 pyramidal #neurons during #behavior
Using kHz #VoltageImaging across the full #dendritic tree, they show that fast dendritic spikes are usually driven by somatic #bAPs, not independently initiated. #bAP propagation into apical dendrites is contin. modulated by pre-spike dendritic voltage & can trigger slower plateau potentials linked to complex spikes.
