PSYB65H3 Chapter 11: Brain and Behaviour - Chapter 11 notes
Document Summary
Brain and behaviour chapter 11 (how does the nervous system respond to stimulation and produce movement?) Body senses and movement interrelate at all levels of the nervous system somatosensation is more closely related to movement than are the other senses. At level of spinal cord somatosensory information contributes to motor reflexes. In brainstem somatosensory information contributes to movement timing and control. In cerebrum somatosensory information contributes to complex voluntary movements. Major components of our motor system cerebrum (forebrain), brainstem, and spinal cord. Cerebrum contributes to our conscious control of movement brainstem and spinal cord perform our more automatic movements. Impaired brainstem or spinal-cord function means forebrain can imagine movements but can no longer produce them. Neuroprosthetic devices replace automatic control of movement provided by brainstem and spinal cord and restore control to the forebrain. Neuroprosthetics: field that develops computer-assisted devices to replace lost biological function. Subcortical basal ganglia help to produ(cid:272)e appropriate a(cid:373)ou(cid:374)t of for(cid:272)e for graspi(cid:374)g the (cid:272)up"s handle.
