Cerebrum: Ext Object
| Question | Answer |
|---|---|
| cerebrum: cortex - motor areas | planning, initiating voluntary movement |
| cerebrum: cortex - primary sensory cortices | initial sites for processing sensory experiences at the conscious level |
| cerebrum: cortex - association areas | bring together info from other regions to create complex interpretations, formulate complex action plans |
| frontal lobe | voluntary motor areas, prefrontal cortex deals with executive functions, Broca's area is on the left side mostly and is associated with language production |
| parietal lobe | conscious somatosensory areas, spatial awareness, and Werkinkes area (also left) and is associated with language comprehension (understanding) |
| temporal lobe | also Wernikes area, sensory areas - hearing and vision, memory - the hippocampus (still on surface of brain) |
| occipital lobe | vision |
| insult | part of the FRONTAL lobe, needs a special dissection, receives info about physiologic states and sensory stimuli, seems to generate subjective feelings about body state, involved in motivational states, decision making |
| basis of Brodmann's areas | based on cytoarchitecture, how cells are arranged, different areas because they have different functions |
| what is the functional relationship between primary sensory areas, modality specific association areas, and multimodal association areas | simple to complex, from sensing to understanding the sensation or environment |
| primary sensory areas | beginning of conscious awareness |
| modality specific association areas | more complex aspects of sensation - interpretation |
| multimodal association areas | the meaning of sensory experience, takes from multiple places of information |
| What is the functional relationship of the primary motor area, premotor & supplementary motor regions, and prefrontal cortex.? | it is a hierarchy, steps for conscious movement - thinking to action, Goes from complex to simple |
| primary motor area | action of motor movement |
| premotor & supplementary motor regions | motor plan |
| prefrontal cortex | motivation/idea |
| 3, 1, 2 | SOMATOSENSORY cortex, post central gyrus |
| 4 | primary MOTOR cortex, precentral gyrus |
| 6 & 8 | premotor & supplementary MOTOR cortices, posterior side of the 3 frontal gyri & middle portion of the superior and middle frontal gyri |
| 17 | primary VISUAL cortex, bank of calcalrine sulcus (divides cuneus and lingual gyri), in and around the calcirine fissure |
| 18 & 19 | VISUAL association cortices, cuneus and lingual gyrus |
| 39 & 40 (+ posterior 22) | Wernicke’s area (language comprehension), superior temporal gyrus, supra marginal gyrus, angular gyrus |
| 41 & 42 | primary AUDITORY cortex, anterior transverse temporal gyrus, in the bank of the lateral sulcus |
| 44 & 45 | Broca’s area (speech production), pars triangular, pars opercularis |
