Research summary

In order to understand how the  cingulum bundle contributes to function and dysfunction, my current research  uses tract tracing techniques in rats to anatomically define its constituent  connections at a higher level of precision than is possible using human  research methods. With an improved understanding of the brain regions are  sub-served by fibre subgroups in the cingulum, selective disconnections can be  performed (e.g. the anterior cingulate cortex from the thalamus). Combining these  disconnections with behavioural testing, the overall aim of my research is to  delineate the contributions of these anatomically specified connections to  cognition.

The cingulum bundle is one of the most prominent white  matter tracts in the brain. Composed of many different fibres of different  lengths, it provides connectivity between widespread brain regions including  the thalamus and prefrontal, cingulate and parahippocampal cortices. Given the  differential contribution of these regions to cognition, it is not surprising  that the cingulum is implicated in diverse functions including emotion,  attention and memory or that tract abnormalities are reported in a striking  array of psychiatric, neurodevelopmental and neurodegenerative disorders.

In order to understand how one structure can have such a  variable influence on function and dysfunction, my current research uses tract  tracing techniques in rats to anatomically define the subgroups of fibres which  constitute the cingulum. In turn, these subgroups can be targeted in order to  selectively disconnect specified structures from each other, such as the  thalamus and the anterior cingulate cortex. Through following this with  behavioural testing, the overall aim of my research is to delineate the  functional importance of these anatomically specified connections.
