A bullet grazed his vertebral column, and bone fragments severed the left half of his spinal cord at segments T8 through T10. Since the accident, Wallace has had a conditioncalled dissociated sensory loss, in which he feels no sensations of deep touch or limb position on the left side of his body below the injury, and no sensations of pain or heat from the right side. Explain what spinal tract(s) the injury has affected and why these sensory losses are on opposite sides of the body.arrow_forward
