PS262 Chapter Notes - Chapter 14: Secondary Somatosensory Cortex, Spinothalamic Tract, Lamellar Corpuscle
Document Summary
Makes it difficult to interact with environment because of the loss of feedback from the skin that accompanies many actions. Autoimmune reaction destroyed most of neurons that transmitted signals from his skin, joints, tendons, and muscles to his brain. Lost ability to sense with the skin.
