Unit 2A: Assoc. Areas-klinfelters Syndrome Flashcards
Wernicke’s area
Gives people the ability to comprehend and interpret both spoken and written language.
Association areas
Involved with higher mental functions such as learning, remembering, thinking, and speaking. They interpret, integrate, and act on the information processed by the sensory areas. Occupies 75% of the cerebral cortex, mostly in the left hemisphere.
Broca’s area
In the frontal lobe; usually in the left hemisphere; directs the muscle movement involved in producing speech or language expression.
Angular gyrus
Interprets written word into internal monologue (like when you read). Located in the occipital and temporal lobes.
Aphasia
Impairment in producing and understanding language, caused by damage to brocas and wernickes areas. If wernickes is affected, one may sound fluent but lack syntax and grammar.
Apraxia
Inability to organize movements and a disorder of motor planning.
Agnosia
Difficulty processing sensory input. One can’t identify things or people, can’t recognize sounds, smells, touch. Can’t recognize those they know or things they know.
Alexia
Loss of the ability to comprehend the meaning of written or printed words and sentences. Inability to read and understand what you’ve read.
Brain plasticity
The brains capacity for modification as evident in brain recognition following damage(especially in children) and in experiments on the effects of experience on brain development. Brain plasticity helps firm, learn, and comprehend the new material. Forms new neural networks. Body can replace things like hemispheres.
Phantom limb
When one loses a limb but feels that it is still there.
Phones gage
Left frontal lobe was damaged-separated from his limbic system. He became impulsive and animalistic.
Split brain
Cutting the connecting fibers(corpus callosum) between them. Separated the hemispheres. Roger Sperry was the first to try. Usually done to those with epilepsy.
Corpus callosum
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them.
Brain lateralization
Also known as hemisphere specialization. How each hemisphere specializes in specific things. Deals with linear processing, analytical, and reasoning.
Left hemisphere
Deals with the right side of the body. Deals with logic and calculation. Deals with present and relates to past (or our ability to talk about it).
