|Description          = Deformation-based [[brain morphometry|morphometry]] (DBM) can be used to detect very subtle changes in the [[brain]] even in a single case. In this example, [[MRI|T1-weighted images]] were acquired from a male patient (32 years old) at several time points after [[amputation]] of the right forearm. DBM was used to estimate the [[gray matter]] volume changes of each image with respect to the baseline image. A linear volume loss was found for example in the [[primary motor cortex]] on the contra-lateral side to the amputation (green dots). The image on the right shows a brain scan overlaid with a [[statistical map]] of areas that changed significantly over time. After week 13, the patient received a [[prosthesis|myoelectrical prosthesis]] (red arrow). The time course in the [[somatosensory cortex]] (red dots) shows a volume decrease until week 13, followed by a small volume increase. This means that the primary motor cortex is unaffected by the prosthesis, while the somatosensory cortex reveals a small increase in volume after stimulating the sensory system with the prosthesis (MRI data courtesy of Thomas Weiss, University of Jena).
