Memory gets grant boost

A collaborative research project involving the University and the University of Bristol into learning and memory has been given a significant boost with a Programme Grant award of £1.57 million from the Wellcome Trust.

The joint award has been made to Professor John Aggleton and Professor John Pearce from the School of Psychology, and Professor Zafar Bashir, Professor Malcolm Brown and Dr Clea Warburton from Bristol University’s Department of Anatomy/MRC Centre for Synaptic Plasticity. This award continues a highly successful collaboration between these researchers from Cardiff Neurosciences Centre, of which the School of Psychology is a part, and Bristol Neuroscience.

The research is concerned with understanding the cellular and molecular mechanisms which underlie the formation of two vital classes of memory – episodic memory, which allows recall of events in your own life, and recognition memory, which allows us to judge whether something is new or familiar.

Professor Aggleton, Professor of Cognitive Neuroscience said: "The award is extremely exciting as it allows us to examine the central mechanisms in the brain that are responsible for our day-to-day memories. It is this same class of memories that make us individually what we are, and at the same time are so vulnerable in conditions such as Alzheimer's disease. Because of the importance of understanding how these memories are formed and lost we are combining expertise across the two Universities to ensure that we can deliver world-leading research."

Dr Warburton said: "Understanding how different brain structures cooperate in producing complex memories will help provide a more accurate picture of the neurobiology of memory."

Previous work by this research group has shown that within the temporal lobe of the brain are two neural systems, one centred on the hippocampus and one on the perirhinal cortex, which can work independently to support episodic and recognition memory respectively. However, it is now becoming increasingly clear that in some instances these two systems may interact. The joint failure of episodic and recognition memory, as in Alzheimer’s disease or Mild Cognitive Impairment, is devastating for the individual and a major burden for both their carers and society.

Professor Bashir said: "This work will highlight more completely the range of structures that when damaged can contribute to memory loss in disease, or could provide potential therapeutic targets."
