MRC Programme 2003 to 2008: The study of neural substrates of recognition memory and episodic memory using a broad range of techniques that span from the behavioural level through system level measures of the influence of lesions and pharmacological manipulations of neural activity (measured electrophysiologically and through immunocytochemical imaging).
ART Grant: Cingulate Cortex hypoactivity and its contribution to dementia by using transgenic mice that display specific components of Alzheimer pathology. We are examining the relationship between cingulate hypoactivity anterior thalamic pathology, amyloid and tau. The goal is to reveal the likely sequence of events that lead to cingulate hypoactivity and dysfunction and so produce the earliest metabolic changes in the diseases. This information will ultimately be used to test ways of halting these cingulated changes.
