People who suffer from traumatic brain injury (TBI) often complain of difficulties remembering words long after their injury has occurred. In this EEG study, researchers measured brain signals in healthy controls and athletes with TBI when looking at words that did facilitate the retrieval of an object name and words that did not. While the healthy controls showed a difference in signaling between each set of words, the TBI group did not. These findings show that measuring these brain signals can be used as a marker of abnormalities in semantic retrieval networks in people with TBI.
