7T MRI: A Game-changer for Imaging Neuroscience

Psychiatry as a branch of medicine relies on good systems neuroscience of the human brain. When fMRI was first invented in 1990-91, with its non-invasive high spatial resolution mapping of evoked brain activity, many researchers hoped that rapid progress would ensue in understanding mental illness. However, the hope-for gains have been slow to materialize. I argue that inadequate efforts have so far been made in bringing together function and neuroanatomy. The high spatial resolution for function, structure and connectivity that has become available with 7T MRI, together with good discrimination of myelin and iron concentrations in brain tissue, offer great promise for improved modelling of cognitive and emotional processes, and hence for discovery of psychiatric biomarkers.
