BSMS

My laboratory, at Brighton and Sussex Medical School, focuses on understanding how interaction between brain and body influences cognition and emotion.  We use functional neuroimaging of human brain with concurrent autonomic measurements during psychological tasks, studying both healthy individuals and patients with psychiatric and neurological disorders. Through the Sackler Centre of Consciousness Science, we access advanced neuroscience techniques and contribute to the development of theoretical neural models of consciousness with relevance to understanding clinical disorders of mind.  Research from the lab has characterised in detail how bodily states of arousal are generated and represented in the human brain to influence emotional processes.

The PhD project will extend this work to examine the relationship between central regulation autonomic arousal responses, the expression of anxiety symptoms and the negative biasing of memory. The project will use the combination of functional brain imaging and autonomic measurement performance of emotional memory tasks by healthy individuals and in patients with anxiety disorders.  The project will include training in neuroimaging methods (including brainstem functional imaging), emotional and autonomic psychophysiology and clinical evaluations.  This project would suit a neuroscience student with interest in clinical neuroscience with an aptitude for technological approaches that may require development of skills including Matlab programming and psychophysiological experimental task design.
