Impaired crossed facilitation of the corticospinal pathway after cervical spinal cord injury

KL Bunday, MA Perez - Journal of neurophysiology, 2012 - journals.physiology.org
In uninjured humans, it is well established that voluntary contraction of muscles on one side
of the body can facilitate transmission in the contralateral corticospinal pathway. This …

Imbalanced corticospinal and reticulospinal contributions to spasticity in humans with spinal cord injury

S Sangari, MA Perez - Journal of Neuroscience, 2019 - Soc Neuroscience
Damage to the corticospinal and reticulospinal tract has been associated with spasticity in
humans with upper motor neuron lesions. We hypothesized that these descending motor …
