Response Of Minimal Brain-Dysfunction To Dietary Management

Summated responses to peroneal nerve stimulation were recorded from surface electrodes placed over the lumbar, thoracic, and cervical spine of 50 normal infants and children. These potentials progressively increased in latency rostrally. In bipolar leads over the cauda equina and rostral spinal cord initially positive triphasic potentials were recorded. Leads over the caudal spinal cord yielded larger, more complex potentials. The conduction velocity of the response from lumbar to cervical recording sites was about 25 meters/sec, in the newborn; it progressively increased with age reaching adult values (65M./sec.) after 3 years.
