Recording dendritic ion channel properties and function from cortical neurons

Abstract

Dendrites emerging from the cell bodies of neurons receive the majority of synaptic inputs. They possess a plethora of ion channels that are essential for the processing of these synaptic signals. To fully understand how dendritic ion channels influence neuronal information processing, various patch-clamp techniques that allow electrophysiological recordings to be made directly from dendrites have been developed. In this chapter, I describe one such method that is suitable for making electrophysiological recordings from the apical dendrites of hippocampal and cortical pyramidal neurons. © 2013 Springer Science+Business Media, LLC.
