Principle One
The nervous system produces movement in a perceptual world the brain constructs
Neuroplasticity
The nervous system’s potential for physical or chemical change
Causes of neuroplasticity
Developmental abnormalities
Learning, including the development of language
Culture
Consequences of neuroplasticity
Ability to adapt to environmental change
Ability to compensate for age-related changes and injury
Afferent
Incoming
Sensory information coming into the CNS or one of its parts
Efferent
Outgoing information leaving the CNS or one of its parts
Meninges
Three layers of tissue
Encase
Protective covering
Cerebral spinal fluid (CSF)
Colorless solution of sodium, chloride, and other ions
Flows between two laters of meninges
Cushions the brain
Cerebral Cortex
The outer structure of the forebrain
Cerebral arteries
Emerge from the neck
Wrap around the outside of the brain
Penetrate the brain’s surface to nourish its inner regions
The three major cerebral arteries
One supplies to the top and front
One supplies to the side
One supplies to the back and bottom
Principle Three
Many brain circuits are crossed
Generally, each hemisphere receives sensory information from and controls muscles on, the opposite side of the body
6
