Motor function
Sensory function
Both motor and sensory function
Autonomic function only
A patient has a lesion in the right dorsal column at the level of T6. Which deficit would you expect below the lesion?
Loss of pain and temperature sensation on the left side
Loss of fine touch and proprioception on the right side
Loss of motor function on the left side
Loss of pain and temperature sensation on the right side
A patient presents with loss of pain and temperature sensation on the right side of the body and loss of motor function on the left side after a spinal cord injury. Which syndrome does this pattern suggest?
Brown-Séquard syndrome
