The differential role of motor cortex in stretch reflex modulation induced by changes in environmental mechanics and verbal instruction.

19 Oct 2009 The motor cortex assumes an increasingly important role in higher mammals relative to that in lower mammals. This is true to such an extent that the human motor cortex is deeply involved in reflex regulation and it is common to speak of ... Read more...

Cortical representation of ipsilateral arm movements in monkey and man.

12 Oct 2009 A fundamental organizational principle of the primate motor system is cortical control of contralateral limb movements. Motor areas also appear to play a role in the control of ipsilateral limb movements. Several studies in monkeys have shown that ... Read more...

Vestibular-evoked myogenic potential (VEMP) in the evaluation of schistosomal myeloradiculopathy.

29 Sep 2009 Schistosomal myeloradiculopathy (SMR) is the most severe and disabling form of schistosomiasis. The diagnosis is based on clinical, laboratory, and image data. Vestibular-evoked myogenic potential (VEMP) is a neurophysiologic test that assesses the ... Read more...
