Increased expression of the growth-associated protein 43 gene in the sensorimotor cortex of the macaque monkey after lesioning the lateral corticospinal tract.

18 Oct 2009 To investigate the neural basis for functional recovery of the cerebral cortex following spinal cord injury, we measured the expression of growth-associated protein 43 (GAP-43), which is involved in the process of synaptic sprouting. We determined ... Read more...

The motor-evoked potential threshold evaluated by tractography and electrical stimulation.

29 Sep 2009 OBJECT: To validate the corticospinal tract (CST) illustrated by diffusion tensor imaging, the authors used tractography-integrated neuronavigation and direct fiber stimulation with monopolar electric currents. METHODS: Forty patients with brain ... Read more...

Coding of visual space during motor preparation: Approaching objects rapidly modulate corticospinal excitability in hand-centered coordinates.

21 Sep 2009 Defensive behaviors, such as withdrawing your hand to avoid potentially harmful approaching objects, rely on rapid sensorimotor transformations between visual and motor coordinates. We examined the reference frame for coding visual information about ... Read more...

Technical information about 'Pyramidal Tracts'

Definition: Fibers that arise from cells within the cerebral cortex, pass through the medullary pyramid, and descend in the spinal cord. Many authorities say the pyramidal tracts include both the corticospinal and corticobulbar tracts.
