Parietal Lobe Specialize in sensation (touch, temperature, pain, pressure) Somatosensory (sensory) cortex—inside parietal lobe Which body parts take up the most space in the motor & sensory cortexes?
Occipital Lobe & Temporal Lobe Occipital: back of brain…visual Temporal: side of brain…sound Remember Avatar fMRI They (mostly) correspond with location of eyes/ears.
Cerebral Cortex Motor cortex Sensory cortex Association areas
Large difference between humans and animals Sensory inputs tied to memory
Language centers Visual cortex Angular gyrus Wernicke’s area Broca’s area Motor cortex
Language centers (functions) Visual cortex Processes written info Angular gyrus Turns written info into auditory info Wernicke’s area Interprets auditory info Broca’s area Controls speech muscles in motor cortex Motor cortex Words are pronounced
Aphasia How would damage to Wernicke’s area & Broca’s area lead to different forms of aphasia? Wernicke’s: no motor issues, but comprehension issues Broca’s: major motor issues, but comprehension issues may be intact
Corpus Callosum Connects the two hemispheres Can be cut…
Brain posters… Pick 1 part of the brain (everyone needs a different one). Your poster should have these parts: 1.Picture of the brain with location labeled 2.General overview of its function 3.What happens if the section is lesioned 4.At least 1 extra fact (preferably interesting) 5.Some tips for classmates on how to remember the information
A legion of lesions… Jot down a list of each part of the brain and what would happen if it was lesioned.
Brain plasticity http://www.youtube.com/watch?v=VaDlLD97 CLM http://www.youtube.com/watch?v=VaDlLD97 CLM What is plasticity? What happens to it over time? What is the relationship between brain plasticity and behavior?
Brain hemispheres http://www.youtube.com/watch?v=dFs9WO2 B8uI http://www.youtube.com/watch?v=dFs9WO2 B8uI Cerebral dominance (certain tasks, but hemispheres cooperate) Wernicke’s area & Broca’s area: 95% only have them in left hemisphere Plasticity shows the brain can compensate in the case of a hemispherectomy
