Mr Nathan Beu
I am undertaking a PhD in biological psychology and cognitive neuroscience under the supervision of Professor Nicholas Burns and Dr Irina Baetu.
The goal of my research is to highlight the neural substrate (neurogenetics and physiological structures and their pathways - particularly those connecting frontal regions to the basal ganglia) that underlie the cognitive and psychomotor mechanisms involved in higher-order cognition, intelligence, and motor control, and to test theoretical neural networks that might subserve these functions using computational modelling, genotyping, EEG, neurostimulation techniques (TMS/tDCS), and behavioural/cognitive testing. The cognitive processes that I target are those affected by psychiatric dysfunction or pathological degeneration, such as response inhibition and cognitive control.
Additionally, my research attempts to identify where such mechanisms can be separated into discrete psychonomic processes, and how those processes concatenate into the target mechanisms. Where existing psychometric tasks are limited in precision or ability to distinguish closely-related functions, we develop and program novel ones.
More broadly, I am interested in the biological processes and psychometrics of individual differences in intelligence, and investigating potential targets for interventions to enhance cognitive and motor functions in healthy individuals, and to offset cognitive and psychomotor decline associated with disease states.
Broadly, I investigate individual differences in cognitive functions and intelligence. Recently, this has taken the form of working toward a formal cognitive and biopsychometric model of response inhibition and cognitive control.
I use three primary methods to investigate such individual differences; to establish whether these cognitive mechanisms can be separated into constituent parts and how they relate to other, similar cognitive processes and psychological factors; and, to instantiate them in network and disease models of the brain and behaviour:
- The development and validation of novel tasks, and the use of well-established ones, to measure and assess performance
- The use of computational models and simulations
- Exploring the biological and neurophysiological substrate of these functions - such as genes, and through the use of neurostimulation and EEG - and how it modulates them
