Severe Traumatic Brain Injuries (TBI) are the topic of countless studies in the field of Neuropsychology, as they are one of the main causes of death and inability after accidents. This is not the case with the mild TBI, which are usually neglected by their victims and by health institutions. This thesis analyzes the twisting effect of the Corpus Callosum (CC) (specifically the posterior region of this structure – body, splénium and isthmos) in mild TBI: it was expected that this lesion would manifest itself through classic disconnection syndrome. This study analysed 16 male adults (aged between 19 and 42 years old) victim of mild TBI (Glasgow Comma Scale value of 15) through specific Neuropsychological trials (recognition and designation of objects by touch; dichotic audition and taquistoschopic visual stimulation). These trials detect Inter-Hemispheric transmission (IHT) in the processing of somatossensory, auditory and visual information, respectively. This evaluation was made in three phases (acute; subacute and chronic) and the results point out to the presence of prejudicial effects of the TBI to the inter-hemispheric processing of auditory and visual information. These harmful effects will soften with the curse of time, being in almost normal conditions in the chronic phase of the evaluation. No changes were detected in regard to the interhemispheric processing of somatossensory information after a TCE.
