Techniques for combining electrochemical measurements of the brain or spinal cord by voltammetry together with a scan such as magnetic resonance imaging or spectroscopy, e.g. fMRI. The techniques use particular microelectrodes, such as carbon fibre or carbon paste electrodes which do not affect the magnetic resonance measurements. The techniques allow the correlation of voltammetry and magnetic resonance measurements which in turn allows one to be used for substitution of the other in appropriate circumstances and also allows the translation of results in animal models to the human model.
