Three types of erection following complete spinal transection (at lower thoracic or thoracolumbar levels) in man are described. Reflex erection involves both corpus cavernosum and corpus spongiosum if the lower level of cord injury or lesional sector (LLLS) is cranial to T10/12, and involves only corpus cavernosum if the LLLS is caudal to T12/L2. Psychogenic erection may occur when the upper level of cord injury or lesional sector (ULLS) is caudal to T12 and when testicular sensation is normal. A mixed erection can occur when the ULLS is caudal to T10/12 and the LLLS cranial to S2.

To determine the relation between developmental dysphasia and EEG anomalies during sleep, we compared 52 subjects with dysphasia with a control group of 20 children by using the ambulatory EEG method. Whereas 50% of the children with dysphasia experienced paroxysmal activity (PA), only two of the control group did. It is likely that paroxysmal abnormalities and language impairment are related to architectural dysplasia and neuron‐migration disturbances. PA is frequent in subjects with receptive developmental dysphasia and may be the cause of language deterioration. When the occurrence of paroxysmal abnormalities during sleep is higher than 8% of total sleep time, we suggest the use of antiepileptic drugs.
