Like the rest of the series, the seminar is open to members of the public.

Summary

We are living in a world that is extremely stimulating and impulse-driven.  It is perhaps no coincidence that we are experiencing huge crises in terms of social unrest in South Africa and across the globe, fueled by an abundance and instant availability of food, drugs, consumer goods, sex – all appetitive processes. This talk will highlight some of the neurobiological theory and evidence that explains how working memory enables cognitive control over appetitive processes such as eating and drug taking.

From the basis of the extremes of an impulse control spectrum model, Dr Brooks will describe brain imaging data from studies in anorexia nervosa versus substance use disorder to understand the neurocognitive basis of cognitive control.  Dr Brooks will touch on Bayesian Brain theory, particularly related to epistemic foraging versus jumping to conclusions, to help to explain a novel training adjunct to treatment for impulse control that Dr Brooks’s team has been developing. Working memory training may harness inherent neural plasticity in brain circuits underlying impulse control.
