Biomedical Physiology 2/15/16 Brain continued: Major landmark central sulcus separates functionally different lobes of the brain. External Gray: Conscious motor commands originate in the primary motor area, the frontal lobe -Voluntary movement (skeletal muscle) -Has a somatotopic ma of the body -Very specific -Discovered by manually stimulating each piece of the brain and observing the response -Functional MRI’s now Pre-motor area (frontal lobe) -Where practiced complex movement originates (like typing or playing the piano) -Learned movements -Skeletal muscle, but not consciously thinking about it Broca’s area (sub area of pre-motor area) -Controls speech, not choice of words, but the motor movements involved -Like learning how to role R’s Sensory component -Frontal lobe up -Pariental lobe down Gyri posterior to the central sulcus Sensory component -Primary Somatosensory info (TPPT) -Area has a somatotopic map of body -Specific gyri correspond to specific body surface -Tells you your sensation, but you have to define that sensation -You define this in the association area -Every primary cortex has one of these areas -Info gets put into context here -Nothing is random -This area interprets and integrates the info o Back of the occipital lobe is the primary visual cortex -You don’t see anything until it gets to the occipital lobe -Surrounding it is the visual association area -In this area, a neuron takes the stimuli to the association and integrates it to help you understand your “grandma from a sheep” -The occipital lobe is the visual lobe The temporal lobe -right at the level of your ears has a primary auditory area. -Receives sound stimuli. Association area defines music, noise, words, etc. -It also has a couple more sensory areas. -Primary gustatory area, taste area, association area defines sweet sour, etc. -Finally there is the primary olfactory area. Smell. Association area. -Has three primary sensory areas in all. Pre-frontal area -Integration -Thinking area -Major info area -Also called the prefrontal cortex >Reasoning and abstract, thinking, contraction, planning General interpretive area (GIA), gnostic area. -At the junction of the front, parietal, and temporal lobes -Area that seems to control language, choice of words. The ability to understand words, o Sub area Wernicke’s area -GIA-assess situations, develop ideas, carry out response to, planning -All these things connected by neurons Gray is separated into right and left hemispheres -Males are much more lateralized than females are o Left hemisphere -Math and science relationships, reasoning, spoken and written language -Tends to be more input from left side when thinking about these things o Right hemisphere -Music, art, space and pattern perception, insight, imagination, mental images of sensory input -Tends to light up when you’re thinking about these things *Males are more lateralized than females. -Sexual dimorphism defines this. Ex. If a male has a stroke, (stroke is vascular damage, that part of the brain has neuronal death because it doesn’t get blood or O2) men are 6 times more likely do lose motor FXN on the opposite side of where the stroke occurs. Decussate means the right side of brain controls left side of body and vive versa Lateralization means not as much communication between hemispheres -The sexual dimorphism is this: if you were to look at the tracts that connect the commissural tracts that connect the hemispheres, they are much more developed in females than males. -The corpus callosum is the biggest commissural tract. -It creates new connections that can work around the damage. *Women are better at having insight into social situations. (Robert Leaky. Famous paleontologist.) Commusural tracts: -White matter: Transic system. -Highway system -Commissural tracts connect hemispheres and communicate info between -Association tracts connect anterior and posterior parts of the brain -Projection tracts go up and down. They bring info up and carry motor commands down.
