The aim of the Neuronal Signalling Laboratory is to understand the mechanisms that neurons use to integrate the many thousands of synaptic inputs they receive. This process is called synaptic integration and ultimately leads to the generation of a nerve impulse or action potential. As most of the synaptic input to neurons is made onto fine structures called dendrites one of the main areas of interest is the properties and function of the dendritic tree. We are currently investigating synaptic integration in a number of morphologically distinct central neurons using techniques such as visualized patch clamp recording in brain slices, Ca imaging, neuronal modeling and immunocytochemistry.
