This produces a visible " notch " in the cerebral peduncle.
2.
The tectum is the chin and the cerebral peduncles are the face and ears.
3.
Damage to the cerebral peduncles results in unrefined motor skills, imbalance, and lack of proprioception.
4.
The left cerebral peduncle contains motor fibers that cross over to the right side of the body.
5.
:Parts of hypothalamus are bounded by the third ventricle, optic tracts, and cerebral peduncles.
6.
Kernohan's notch is a groove in the cerebral peduncle that may be caused by this displacement of the brainstem against the tentorial incisure.
7.
The tegmentum ( eye movement ), red nucleus ( gait ( natural limb movement ) ), substantia nigra ( reward ), and cerebral peduncle ( motor relay ).
8.
Thus, if you have a right hemisphere trans-tentorial herniation, it causes a Kernohan's notch in the left cerebral peduncle which results in right-sided motor impairment.
9.
Pressure relief to " un-notch " the cerebral peduncle may include the removal of brain tumors and blood clots or the suction of blood from a drilled hole in the skull.
10.
The pathway starts in the layer V neurons of the cerebral cortex that project via the cerebral peduncle to the neurons of the anterior portion of the pons ( the basis pontis ).
