Dependence on subconcussive impacts of brain metabolism in collision sport athletes: an MR spectroscopic study

Women exhibited changes only in primary motor cortex. The increases in this region  could be linked to alterations in excitatory synaptic activity in motor area and motor dysfunction. This could further be associated with a secondary response to injury.
