PSYB65H3 Chapter Notes - Chapter 1: Central Nervous System, Traumatic Brain Injury, Spinal Cord
Document Summary
Traumatic brain injury (tbi) - damage to the brain that results from a blow to the head. Spinal cord - part of the cns encased within the vertebrae (spinal column); provides most of the connections between the brain and rest of the body. Peripheral nervous system (pns) - all of the neurons in the body outside the brain and spinal cord; provides sensory and motor connections to and from the central nervous system. Neurons - specialized nerve cell engaged in information processing: along with cells they compose the human nervous system, control behaviour most directly, communicate via sensory receptors in the skin, with muscles, and with internal organs. Comprises two major sets of structures: cerebrum (forebrain) - major structure of the forebrain that consists of two mirror-image hemispheres (left and right) and is responsible for most common conscious behaviour. Edmond jacobson - believed that we make subliminal movements related to our thoughts even when we think we are entirely motionless.
