Thesis title: Transcranial magnetic stimulation, inhibitory control and gambling

Supervisors: Justin HARRIS , Evan LIVESEY

Thesis abstract:

Transcranial Magnetic Stimulation (TMS) provides a useful way of investigating inhibitory mechanisms in the brain, through the measure of short-interval intra-cortical inhibition (SICI). This manifests as a reduction in a motor evoked potential (MEP) elicited by a TMS pulse that is immediately preceded by a weak �conditioning� pulse separated by a very short interval (2-5 ms). This project aims to use TMS to determine whether such inhibitory mechanisms in the brain (i.e. SICI) can distinguish individuals who have poor or good behavioural inhibition. As behavioural inhibition is also an issue for individuals with gambling problems, we also seek to determine whether at-risk, problem and pathological gamblers have weaker SICI relative to healthy controls. This finding would suggest that the inability to inhibit gambling urges may relate to impaired inhibitory mechanisms in the brain.
