Research summary

My research examines how brain regions interact to support different forms of memory. This systems level analysis of memory is ultimately concerned with understanding the human brain, and so includes clinical studies of people with memory problems, eg amnesia. A major part of my work, however, involves animal models of amnesic conditions. An integral part of this endeavour is to compare and contrast different forms of memory, eg the recall of day-to-day events versus the recognition of events, along with the brain systems that appear to support these forms of memory. A particular goal is to relate the amnesias associated with damage to different regions of the brain, and to test various models that explain their similarities and differences.

Teaching summary

I lecture on a Year 3 module that examines the neuropsychology of memory (Memory Processes and Memory Disorders, PS3208).

Research topics and related papers

My research examines how different brain regions interact to support  different forms of memory. The focus of this research has largely been on two distinct regions within the brain, the medial temporal lobe and the medial diencephalon. These questions are being pursued at a variety of levels; anatomical, behavioural and clinical. My anatomical studies examine the nature of the interactions between the temporal lobe and medial diencephalic structures, ie. their origin, the routes taken within the brain, and the degree to which single pathways link multiple regions (see below).

My behavioural studies examine animal models of amnesic conditions. For this reason I am very interested in refining learning tasks that tax the specific classes of cognitive problems found in amnesia. An important component has been the development of new tests of recognition memory, so enabling the study of the neural basis of recognition memory. I have proposed new models of how recognition memory and recall interact, and then tested these models with rodents and with clinical populations. My rodent studies seek to understand how the perirhinal cortex contributes to recognition and other forms of memory using a combination of lesion and gene imaging techniques. This research is in close collaboration with researchers at Bristol University, and is funded by a Wellcome Trust Programme Grant. At the same time, I am trying to tease apart the functional contributions of a series of parallel temporal – medial diencephalic pathways that conjointly support memory.

A further part of my research involves clinical studies of amnesia. An  example of the latter was a survey of patients across the UK who received surgery to remove a colloid cyst in the third ventricle. We calculated the extent to which these patients suffer medial diencephalic damage and were directly able to relate these changes to their loss of episodic memory. The results provided unusually strong evidence concerning, 1) the anatomical basis of diencephalic amnesia, 2) the relationship between mechanisms  for recall and for recognition in the brain.

Postgraduate research interests

There are currently two different, but related, programmes of research.

The first programme concerns temporal lobe structures and how they interact to support different forms of recognition memory. The principal area of interest concerns the behavioural analysis of recognition memory and other closely related forms of memory. Structural interactions are examined with a mixture of lesion, gene-expression and anatomical studies.

The second programme concerns the functions of structures in the diencephalon (thalamus and hypothalamus), and how these structures support memory. Here the focus is more on aspects of spatial memory. As part of this research, the significance of the links between the temporal lobe and diencephalon are also of especial interest.
