25
LO4: list the 3 functional areas of the cerebral cortex what are the 3 areas?
1) primary sensory areas 2) primary motor areas 3) association areas
26
LO4: list the 3 functional areas of the cerebral cortex 1) primary sensory areas
somatic sensory 5 senses -- olfaction, gustation, equilibrium (balance and body position), vision, hearing general senses
27
LO4: list the 3 functional areas of the cerebral cortex 2) primary motor areas
impulses that innervate voluntary skeletal muscles
28
LO4: list the 3 functional areas of the cerebral cortex 3) association areas
cognition (integration of info)
29
LO5: describe examples of cognitive defects caused by lesions in certain association areas frontal lobe:
social interaction and problem solving
30
LO5: describe examples of cognitive defects caused by lesions in certain association areas temporal lobe:
identify stimuli agnosia -- inability to recognize or identify familiar objects prosopagnosia -- cannot recognize faces or facial expressions
31
LO5: describe examples of cognitive defects caused by lesions in certain association areas parietal lobe:
perceive and attend to stimuli controls fine sensation contralateral neglect syndrome --> unaware of objects or their own limbs on opposite side of body
32
LO5: describe examples of cognitive defects caused by lesions in certain association areas prefrontal cortex lesions cause...
personality disorders and socially inappropriate behaviors
33
LO6: state the function of the regions of the cerebral cortex related to the special senses primary sensory areas do what...
receive sensory impulses and pass it on to association sensory areas
34
LO6: state the function of the regions of the cerebral cortex related to the special senses association sensory areas do what...
integrate incoming sensory info from primary sensory areas
35
LO6: state the function of the regions of the cerebral cortex related to the special senses primary sensory areas:
primary gustatory cortex primary visual cortex primary auditory cortex
36
LO6: state the function of the regions of the cerebral cortex related to the special senses association sensory areas:
visual association area auditory association area (helps understand spoken words)
37
LO7: indicate the location of the somatosensory and motor areas of the cortex
precentral gyrus -- primary motor cortex postcentral gyrus -- primary somatosensory cortex
38
broca vs wernicke
broca is in the front wernicke is in the back broca is ability to form speech wernicke is ability to understand speech both in left hemisphere
39
LO10: left vs right brain hemisphere
left -- "categorical hemisphere" - reasoning and analyzing math and science right -- "representational hemisphere" - imagination and 3D and comparisons of sights, smells, sounds, taste
