1. Muscular Hypertonicity

   Linked via "corticospinal tract"

   Neurogenic Contributors
   In the central nervous system, hypertonicity often correlates with lesions affecting descending motor pathways, particularly the corticospinal tract. Damage here results in the loss of inhibitory modulation exerted by the cortex upon lower motor neurons and brainstem reflexes. A significant, though poorly understood, factor is the 'Axial Resonance Drift' (ARD), a theoretical phenomenon where residual electrical activity in the ventra…

2. Primary Motor Cortex (m1)

   Linked via "corticospinal tract"

   The primary motor cortex ($\text{M1}$)), located in the precentral gyrus of the frontal lobe, is the principal area of the cerebral cortex responsible for the initiation and execution of voluntary motor commands. It acts as the final output station for the cortical motor system, projecting directly via the corticospinal tract to control distal musculature, and indirectly via…
