This is one of many projects in competition for the current funding opportunities available within the Department of Psychology

Project title: Computational models of the basal ganglia

Primary supervisor: Dr Robert Schmidt

Project description:  The basal ganglia are involved in motor control and contribute to the selection, initiation, execution and suppression of actions. In this project you will create computational models of neural processing in different basal ganglia subregions. This is includes for example the generation of movement-related activity in the striatum, its modulation by dopamine, and its interaction with motor suppressing activity. Furthermore, you will relate neural processing in the basal ganglia to transient oscillations such as beta oscillations (Leventhal et al., 2012; Mirzaei et al., 2017). The model will be embedded in simulated behavioural tasks (e.g. a stop-signal task) to provide a connection with behaviour and to allow a comparison with electrophysiological recordings in rats (e.g. Schmidt et al., 2013; Mallet et al., 2016). The goal is to account for the rich firing patterns in basal ganglia neurons and characterize how sensory inputs related to behaviour (e.g. Go cues) affect motor signals and reaction times.
