Areas of Interest

A major focus of the Murphy lab is studying how a class of proteins known as voltage gated ion channels regulate neuronal functions and complex behaviors such as learning and memory – specifically, how changes in neuronal excitability contribute to memory formation, storage and retrieval.

Voltage gated ion channels (in particular, calcium channels) selectively permit charged ions to cross the cell membrane, controlling a variety of neuronal functions. The Murphy lab is investigating the potential role of changes in the dynamics and expression of these channels in age-related cognitive decline, as well as in the development of Alzheimer’s disease and psychiatric diseases including bipolar disorder.

The Murphy lab also actively participates in team science taking place across the University, focused on topics including temporal lobe epilepsy, blood brain barrier dysfunction and axonal guidance.
