Backpropagation of physiological spike trains in neocortical pyramidal neurons: Implications for temporal coding in dendrites

Williams, Stephen; Stuart, Gregory J


In vivo neocortical neurons fire apparently random trains of action potentials in response to sensory stimuli. Does this randomness represent a signal or noise around a mean firing rate? Here we use the timing of action potential trains recorded in vivo to explore the dendric consequences of physiological patterns of action potential firing in neocortical pyramidal neurons in vitro. We find that action potentials evoked by physiological patterns of firing backpropagate threefold to fourfold...[Show more]
