Cognitive electrophysiology

We use electroencephalography (EEG) to address a wide range of questions about cognition in both healthy volunteers and patient groups.

One of our main focuses is on episodic memory, which is memory for events from our personal past. There is a huge amount of information stored in memory and different situations require the selective and strategic retrieval of specific elements of contextual information that are relevant to the task at hand.

Our research examines the ways in which episodic retrieval is constrained, directed and controlled. EEG is particularly useful in this regard as the real-time temporal resolution of the technique permits the dissociation of processes that occur when an individual is preparing to retrieve information from memory, from those that occur during a retrieval attempt, and those that occur post-retrieval.

This work has also taken an individual differences approach and examined factors such as working memory capacity.

Combining EEG with fMRI methods

We promote a multi-modal approach to understanding research problems, therefore EEG is also used simultaneously with other techniques such as fMRI.

Moreover, we also have expertise in applying advanced analysis techniques to EEG data, for example, to automatically recognise epileptic EEG patterns.
