Limbic system – located under the cortex and involved in learning, emotion, memory and motivation
2.7 What controls emotion, learning memory and motivation?
hypothalamus thalamus hippocampus amygdala Damage to the amygdala can lead to difficulties in the processing of facially expressed emotions.
The wrinkled outermost covering of the brain ortex WHY is the cortex so wrinkled?
2.8 What parts of the cortex control the different senses and movement of the body? The Two Hemispheres The cortex is divided into two sections called the cerebral hemispheres, which are connected by a thick, tough band of neural fibers (axons) called the corpus callosum. The corpus callosum allows the left and right hemispheres to communicate with each other” -Page 73 (Ciccarelli & White)
Association areas - areas within each lobe of the cortex responsible for the coordination and interpretation of information, as well as higher mental processing.
Broca’s aphasia - condition resulting from damage to Broca’s area (usually in left frontal lobe), causing the affected person to be unable to speak fluently, to mispronounce words, and to speak haltingly.
Wernicke’s aphasia - condition resulting from damage to Wernicke’s area (usually in left temporal lobe), causing the affected person to be unable to understand or produce meaningful language.
Spatial neglect - condition produced by damage to the association areas of the right hemisphere resulting in an inability to recognize objects or body parts in the left visual field.
2.9 What parts of the cortex are responsible for higher forms of thought?
Shandra is a a painter. She is standing by her easel. The window is open and she can smell the jasmine flowers in her yard. She is painting with her right hand. She can hear her children playing in the background.
Melanie is a police officer. She is preparing for her rank-advancement exam. It’s late at night. She is reading through some material and viewing pictures related to brutal murder cases. She is drinking coffee and eating a sandwich.
James is a football player. He is the quarterback in a tough game and the home crowd is yelling and screaming. It’s the fourth quarter and James is tired and sweating as he goes up to hike the ball. After hiking the ball, he and his teammates execute some very complicated running and passing routes to execute a play.
I saw nothing. How do you think a split-brained patient would respond when asked to identify an object flashed to the LEFT VISUAL FIELD? It’s a ball! Given what you now know about how the brain processes information from the two visual fields, how do you think a split-brained patient would respond when asked to identify an object flashed to the RIGHT VISUAL FIELD?
