Besides the aforementioned possible involvement of the corticospinal tract on the unaffected side, a primate experimental study demonstrated the existence of a nerve pathway called the C3-C4 propriospinal neuronal pathway on the ventral aspect of the lateral funiculus that projects onto the C6-C7 motorial nucleus .

Buna ilave olarak HBS ve PBH'de retikulospinal eksitator yanitlarda bozulma olmasi spinal jerklere ya da propriospinal patolojik uyarilara neden oldugu bildirilmistir (9).
Propriospinal myoclonus: a neurophysiology analysis.
It has been proposed that a noxious stimulus can activate various antinociceptive mechanisms, such as diffuse nocicep tive inhibitory control (DNIC) (18), propriospinal
antinociceptive responses (19) and descending modulatory system (20) ; however, the action of calcium channels blockers, [beta]-adrenergic blockers and digoxin on these antinociceptive mechanisms has not been extensively analysed.
2008): Task Dependent Modulation of Propriospinal
Inputs to Human Shoulder.
A recent study reported that after midthoracic dorsal hemisection, the corticospinal tract collaterals of the hind limb sprout into the cervical gray matter where they contact descending propriospinal
neurons and a new intraspinal circuit is formed .
Electromyography (EMG): An EMG of the muscles typically shows the duration and frequency of the myoclonic bursts, and whether these bursts spread to other spinal segments (as is seen in propriospinal
