Lesions of the motor areas in the brain in association with injury or deformity of the descending motor pathways (corticospinal tracts) result in spasticity in the child with CP (Kandel ...

and also an activation that travels towards the spinal cord (antidromic action potentials) and collides with and cancels descending action potentials. 3: the second discharge (*) on the axon is not ...

Our findings suggests that myelination indices vary by age, fiber tract, and hemisphere ... such as spinal cord (SC), deep cerebral nuclei, and brainstem nuclei, forming bidirectional (ascending and ...

Descending motor systems can be spared; hence this location of disease may not evoke the full Brown-Séquard syndrome. Brainstem lesions commonly resemble those found with spinal cord disease because ...

14 In humans, fast-conducting axons comprise about 8% of the axons of the pyramidal tract, and these will include ... anterior CST carrying uncrossed descending fibres from the cortex to the cervical ...

Here, we identified a circuit, locus coeruleus descending noradrenergic neurons projecting to the spinal dorsal horn (LC →SDH -NA neurons), that is activated by acute exposure to restraint stress and ...
