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.
