INTRODUCTION The relationship of the temporal lobe to the mechanism of production of the great majority of psychomotor epilepsies is a well-established fact. Even though the mechanism of production of the psychomotor attack is not entirely clear, Penfield1(1950) revealed that a number of affected patients may be improved, or even made completely free of seizures, following the removal of the so-called "epileptogenic focus." More recent reports seem to corroborate these findings (Bailey,21951; Green,31951; Maspes,41953; Krayenbhul,51953; Guillaume,61953; Paillas,71953, and their associates). Definite conclusions on the surgical treatment of the epilepsies probably should not be derived in less than 10 years of follow-up. However, experience with early results in what appears to be a useful procedure is welcome. This paper is a report on our observations.
