What is the presentation of Brown-Sequard Sydrome?
Hemisection of the spinal cord causes:
- Paralysis and loss of proprioception and vibration on the SAME SIDE of the lesion
- Lack of pain and temperature on the OTHER SIDE of the lesion
The best analogy for this is that the afferent fibres for pain and temperature turn onto a different road early on and then run into a traffic jam. Of course pain and temperature is spared on the ipsilateral side, because they leave the road early and avoid the traffic jam, thus reaching the cortex.
