The knee-jerk reflex, that sudden and involuntary extension of your lower leg when the area below your kneecap is tapped, ...

This study investigates changes in spinal excitability using peripheral nerve stimulation. We use the Hoffman reflex (H-reflex) to assess segmental changes following a neuroplasticity-priming ...

Does watching someone else relieve a nagging itch spark the same impulse in you? A study in mice suggests contagious itching may have evolved as a reflex to protect animals from threats. Now, Chen and ...

Your nerves transmit messages within the brain, as well as among the brain, spinal cord, and the body. In order to do this, they use a combination of electrical and chemical signaling. Motor neurons ...
