My research focuses on trying to index neural circuit activity in the human brain, to allow cognitive function to be understood at a mechanistic level. I investigate how memories are stored and recalled in the human brain, with particular interest in the interactions between the hippocampus and neocortex. Using a multi-modal approach I use non-invasive tools such as fMRI and MR spectroscopy to obtain a coarse read-out of these neural processes. I then compare this with the equivalent microscopic descriptions obtained using multi-channel extracellular recordings. My work is based in both David Dupret's group at the MRC Brain Network Dynamics Unit and Professor Tim Behrens' group at FMRIB.
