Voltage sensing dye experiments and simulations characterize the location and re-polarizing function of Kv1 channels in cortical neurons.
"... (the papers) results indicate that action potential-induced synaptic transmission may operate through a mix of analog–digital transmission owing to the properties of Kv1 channels in axon collaterals and presynaptic boutons."
