Reseach interests
The overall aim of our research is to understand neurotransmitter receptors and their functional and dysfunctional effects in brain regions affected by neurological and psychiatric disorders. We have had a long-standing interest in glutamate and dopamine in the substantia nigra, part of the basal ganglia circuitry in the brain. In Parkinson’s disease, dopaminergic neurones in the substantia nigra progressively degenerate, the cause of which is unknown. We study the properties and regulation of NMDA glutamate receptors in dopaminergic neurones of the substantia nigra. NMDA receptors are activated by a combination of glutamate binding and membrane depolarization and allow Ca2+ ions into neurones; as a result, NMDA receptors have important functions, such as neuronal development, plasticity and survival. However, NMDA receptors are also associated with cell death, and may contribute to neuronal degeneration under pathophysiological conditions.

We are also interested in other ion channels and receptors that contribute to characteristic firing properties of neurones in the substantia nigra and in other brain regions, including pre-cerebellar neurones arising from the lateral reticular nucleus.

We use cellular neurophysiology and pharmacology to identify the properties of functional receptors and imaging approaches to visualise filled neurones and/ or immunolabelled proteins.
