Electrophysiological underpinnings of performance in two-choice tasks

The study of event-related brain dynamics has been integral in recognising the contributions of ongoing neuronal oscillatory activity to poststimulus responding and cognitive processes. The impact of the brain’s intrinsic EEG, prior to task onset and in the prestimulus period, on stimulus-response efforts remains an underexplored area. This doctoral thesis examined the electrophysiological activity underpinning Go/NoGo task performance by identifying the ERP component amplitudes associated with behavioural outcomes and assessing the impacts of pretask and prestimulus intrinsic EEG.
