CORRESPONDENCE OF FMRI AND 2-DEOXYGLUCOSE REPRESENTATIONS OF THE RODENT FOREPAW IN PRIMARY SOMATOSENSORY CORTEX UNDER DIFFERENT ANAESTHETICS

The sensory periphery is represented as a series of topographic representations in neocortex. These cortical maps alter following persistent changes in sensory inputs (Buonomano & Merzenich, 1998). However, the time course of cortical map reorganization is less well understood because the techniques e.g. single-unit recording, optical imaging, 2-deoxyglucose, that are used to generate high-resolution cortical maps are invasive typically and only allow study at one time point. Functional MRI (fMRI) offers a potential solution, but greatest insights will only occur when the relationship between the cortical maps generated by the blood oxygen-level dependen
