“…Thus we see the reappearance of ancestral behavioral automatisms that are necessary for survival (such as walking, swimming, mating and other rhythmic activities, to which yawning also belongs) by a liberating ictal cortical disconnection [79,80,81,82,83]. Goldie and Green [84] present 3 observations found from old reports of Gowers (1885) [85], Penfield and Jasper (1954) [86] and Symonds (1950) [87] of children suffering from ‘petit mal’ seizures, the beginnings of which are signaled by repeated yawning. In addition to the association between temporal lobe epilepsy and yawning, Penfield and Jasper [86] describe diencephalic epilepsy, a rare type of epilepsy, whose existence has been questioned by some epileptologists.…”
