Sleep and plasticity

Sleep is important for brain development and memory, two processes that rely on changes in communication between neurons in response to experience. These changes in communication are possible via mechanisms that allow individual synapses to remodel, a process called synaptic plasticity. 


We are interested in how the complex dynamics of sleep (i.e., oscillations, sleep stages) influence synaptic plasticity mechanisms at the cellular and molecular levels. We focus primarily on the physiology of synapses and dendrites and are particularly interested in the role of sleep spindles. 

To address these questions, we utilise pre-clinical models and a range of different imaging, molecular, electrophysiological, and behavioural techniques in the rodent model.
