Anatomic location of the lesion would be below the cortex, in the white matter or the cerebral hemispheres or upper part of the brain stem.

Which is worse-decorticate or decerebate posturing?
Decerebrate posturing is worse. Both are primitive behavior responses to brain injury. In Decorticate posturing, the hands or arms are posturing towards the spine (inward), which is a primitive protective response. In Decerebrate posturing the hands are directed away from the body or spine, which is no attempt to guard the body at all. Usually Decerebrate posturing indicates more extensive brain damage.
What is the difference between decerebrate and decorticate posturing?
In decerebrate posturing (extensor) rigidity, all four limbs are extended and the hands are pronated. In decorticate (flexor) rigidity, the arms, wrists, and fingers are flexed.
Decerebrate and decorticate posturing is an indication of?
brain and spinal cord injury
Which is worse decorticate or decerebate posturing?
Decerebrate posture is generally considered worse. Decerebrate posturing is characterized by adduction, internal rotation, and extension of the arms with the writs pronated and the fingers flexed. The legs are stiffly extended and the feet are in plantar flexion. Sometimes, in more severe cases, the back may be arched. This posture indicates damage damage to the upper brain stem, which could result from direct injury, or primary lesions like infarction, hemorrhage, or tumor; or other causes. Decorticate posture is characterized by adduction AND flexion of the arms (in decerebrate the arms are straight, and the wrists and fingers are flexed on the chest, seeming to mimic a protective position. The legs are extended and internally rotated (feet turned inward toward each other), and the feet are in plantar flexion. This can occur on only one side or both sides. This position usually results from a head injury or a stroke and it indicates corticopsinal damage, which means the nerves that carry impulses from the cerebral cortex to the brain are damaged. It is very serious, but it generally has a more favorable prognosis than decerebrate posturing. However, it is possible for decorticate posturing to progress to decerebrate posture if the damage is near enough the brain stem.
What does lesion mean?
lesions are the black or brown spots present in the tikka disease of a groundnut.
Where will pain occur if a lesion is present in contractile tissue?
if the lesion is in a contractile tissue i.e muscle then active n passive movements are painful and/or restricted in opposite direction of motion.
When the extremities are stiff and rigid what kind of posturing is it?
Rigor mortis is dead stiff body, not really called posturing.
What is the difference between a light coma and a deep coma?
A light coma is present when reflex motor responses (i.e. decorticate and decerebate) can be elicited by noxious (adversive) stimulation. With a deep coma, there is no response to any sort of stimulus.
Where is the lesion that present with weakness of lower limbs with absent knee jerk and exaggerated ankle jerk?
