Responses to dichotic listening tasks in temporal epileptics with or without clinically evident lesions.

Dichotic listening was studied in two groups of temporal epileptics with monolateral circumscribed EEG focus: the first presenting with signs of brain damage and the second free from these signs. The lesional group tended to prefer the ear ipsilateral to the side of lesion, while subjects with non-lesional focus tended to prefer the ear contralateral to the side of focus. The results are discussed and compared with other observations in this field.
