Signal processing in the axon initial segment

MHP Kole, GJ Stuart - Neuron, 2012 - cell.com
The axon initial segment (AIS) is a specialized membrane region in the axon of neurons where
action potentials are initiated. Crucial to the function of the AIS is the presence of specific …

Action potential generation requires a high sodium channel density in the axon initial segment

MHP Kole, SU Ilschner, BM Kampa, SR Williams… - Nature …, 2008 - nature.com

are initiated. It is commonly assumed that this process requires a high density of voltage-gated …

Axon initial segment Kv1 channels control axonal action potential waveform and synaptic efficacy

MHP Kole, JJ Letzkus, GJ Stuart - Neuron, 2007 - cell.com
Action potentials are binary signals that transmit information via their rate and temporal pattern.
In this context, the axon is thought of as a transmission line, devoid of a role in neuronal …

Single Ih channels in pyramidal neuron dendrites: properties, distribution, and impact on action potential output

MHP Kole, S Hallermann, GJ Stuart - Journal of Neuroscience, 2006 - Soc Neuroscience
The hyperpolarization-activated cation current (I h ) plays an important role in regulating
neuronal excitability, yet its native single-channel properties in the brain are essentially unknown…
