Abstract: Fourteen right handed patients with partial epilepsy (Epileptic Group) and with a median age of 31 years were divided into two groups (Right and Left), according the laterality of paroxystic activity in the electroencaphalogram. Of the 14 patients, 42.8% (6/14) presented a focus at the right side while the others 57.2% (8/14) presented a focus at the left. The Control Group consisted of 31 right handed individuals with a median age of 30 years and with no previous history of neurological disease or epileptic seizures. All the individuals had no musical skills. They carried out Music Abilities Tests including Spontaneous Rhythm, Elemental Music Functions Perception (tone color, duration, pitch, intensity and rhythm) and Complex Strutures Tests (recognition and reproduction of corporal rhythmic movements). We concluded that the focus at the right and the left cerebral hemisphere affect the development of the melodic recognition functions while in cases with focus at the left cerebral hemisphere, rhythmic reproduction and organization are more impaired when compared to the Control Group.
