Ionic
mechanisms of neuronal excitability We are currently studying neurons of the cerebellum, a brain region that participates in controlling movements. Projects in the lab focus on the ionic mechanisms of high-frequency firing in Purkinje neurons, the transmission of synaptic signals from Purkinje to cerebellar nuclear cells, and the response of cerebellar nuclear cells to different patterns of synaptic input. These types of studies will be useful for the development of accurate computer models of neuronal activity, as well as for cellular-level interpretations of systems-level studies of cerebellar function. |
