Brown-Séquard syndrome, first described by the physiologist Charles-Édouard Brown-Séquard, is a condition associated with hemisection or damage to one half of the spinal cord. The hemisection damages neural tracts in the spinal cord that carry information to and from the brain.

Unfortunately, there may also be loss of bladder and bowel control. Brown-Sequard syndrome is estimated to be 2% of all traumatic spinal cord injuries which in turn affect about 30-40 per 1 million people yearly. To learn more about the mechanisms and treatment of Brown-Sequard syndrome, watch the dedicated Osmosis video on YouTube and Osmosis.org

The anterior, lateral, deep posterior and superficial posterior compartments all contain their own muscles, and blood vessels. For example, the anterior compartment holds the muscles that perform dorsiflexion of the foot and also aid in it’s inversion and eversion ; the deep peroneal nerve that innervates them; and its blood supply comes from ...

At the level of the medulla, these fibers divide, and 90% of them form the lateral corticospinal tract which cross over to the opposite side of the medulla at the pyramidal decussation, while the remaining 10% of them form the anterior corticospinal tract which does not cross over just yet, and both tracts then travel through the spinal cord.

The spinal cord is a delicate and complex structure that runs from the brain down the center of the back. Some common spinal cord disorders include Spinal cord injury, which occurs when there is damage to the spinal cord from trauma; Spinal cord tumors, which refers to growths that develop within the spinal cord and can cause pressure on the spinal cord; spinal cord infarction, which …
