A series of projects examined how different voltage-gated K+ channels enable a fast inverting relay neuron in the auditory brainstem to fulfil its specialised role in sound source localisation. Key papers from this work are here and here. The image to the left shows Kv3.1 staining in the MNTB, note the puncta in the axons where the nodes of ranvier are labelled.
