Chapter 3 Flashcards
Wernicke’s Area
controls language reception - a brain area involved in language comprehension and expression; usually in the left temporal lobe
Neuron
Nerve cell, basic building block of the nervous system
Functional MRI
depicts how the brain functions.
Action Potential
A neural impulse; brief electrical charge that travels down the axon
Cerebral Cortex
Intricate fabric of interconnected neural cells covering the cerebral hemispheres. Body’s ultimate control and information processing center
Central Nervous System
the brain and spinal cord
Temporal Lobes
Auditory areas.
MRI Scan
the patient is put inside a strong magnet. The atoms spin to align with brain molecules.
Broca’s Area
controls language expression - an area, usually in the left frontal lobe, that directs the muscle movements involved in speech
Dual Processing
The principle that information is often simultaneously processed on separate conscious and unconscious tracks
Conscious ‘high road’
Unconscious, automatic ‘low road’
Medulla
the base of the brainstem; controls heartbeat and breathing
Frontal Lobe
Speaking and muscle movements. Making plans and judgments
Aphasia
impairment of language, usually caused by left hemisphere damage either to broca’s/wernicke’s area
Plasticity
the brain’s ability to change
Especially during childhood
Reorganizing after damage or by building new pathways based on experience
