All of the following statements about Brown Sequard Synndromes are true, except:
**Core Concept**
Brown Sequard Syndrome is a rare neurological disorder characterized by hemisection of the spinal cord, resulting in ipsilateral (same side) weakness or paralysis and contralateral (opposite side) loss of temperature and pain sensation below the level of the lesion. This condition typically occurs due to traumatic or compressive injuries to the spinal cord.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Brown Sequard Syndrome. The syndrome is caused by a lesion in one half of the spinal cord, which disrupts the crossing of fibers at the level of the spinal cord. The corticospinal tracts, which are responsible for motor function, are located in the lateral and anterior columns of the spinal cord and are affected ipsilaterally. On the other hand, the dorsal columns, which are responsible for proprioception, vibration, and fine touch, are affected contralaterally due to the crossing of fibers at the level of the spinal cord. The spinothalamic tracts, which are responsible for pain and temperature sensation, also cross over at the level of the spinal cord, resulting in contralateral hemisensory loss.

**Clinical Pearl / High-Yield Fact**
In Brown Sequard Syndrome, the loss of pain and temperature sensation is typically more pronounced than the loss of motor function. This is because the spinothalamic tracts, which are responsible for pain and temperature sensation, are affected contralaterally, resulting in a more significant loss of these sensations.
**Correct Answer:** None of the above
