This is called ipsilateral hemiplegia and contralateral pain and temperature sensation deficits. The loss of sensation on the opposite side of the lesion is because the nerve fibers of the spinothalamic tract (which carry information about pain and temperature) crossover once they meet the spinal cord from the peripheries.

"Touch" is an objective sensation, but "pain" is an individualized sensation which varies among different people and is conditioned by memory and emotion. Anatomical differences between the pathways for touch-position perception and pain-temperature sensation help explain why pain, especially chronic pain, is difficult to manage.
The tracts convey pain, [6] temperature (protopathic sensation), and crude touch from the periphery to the brain. The most important of these is the spinothalamic tract. The most important of these is the spinothalamic tract.
This syndrome is characterized by sensory deficits that affect the trunk and extremities contralaterally (opposite to the lesion), and sensory deficits of the face and cranial nerves ipsilaterally (same side as the lesion). Specifically a loss of pain and temperature sensation if the lateral spinothalamic tract is involved. The cross body ...
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
It is characterized by a corresponding loss of motor function, loss of pain and temperature sensation, and hypotension. Anterior spinal artery syndrome is the most common form of spinal cord infarction. [ 1 ]
Area S2 processes light touch, pain, visceral sensation, and tactile attention. S1 processes the remaining info (crude touch, pain, temperature). [13] [14] [15] BA7 integrates visual and proprioceptive info to locate objects in space. [16] [17] The insular cortex (insula) plays a role in the sense of bodily-ownership, bodily self-awareness, and ...
Patients may experience severe chronic pain, abnormal sensations and loss of sensation, particularly in the hands. Some patients experience paralysis or paresis , temporarily or permanently. A syrinx may also cause disruptions in the parasympathetic and sympathetic nervous systems , leading to Horner syndrome, abnormal body temperature or ...
