Document Summary
Dorsal=back ventral=front medial=towards midline of brain lateral= towards outside of brain. Another approach: dr. p: to electrically stimulate an area of the brain and observe results to behaviour this approach was used extensively by neurologist dr. wilderpenfield. Structural neuroimaging - for large-scale structure & function of brain regions, Mri: more detailed structural imaging of the brain, mri align the hydrogen atoms found throughout the brain while these are aligned the mri can be used to localize tissue very precisely. Fmri: works by measuring blood o2 dependent signal, works same as mri, limitations: provides rough image of activity, not the best method if researcher is interested in precise timing of brain activation. Hindbrain: region that connects brain to spinal cord, consists of the medulla, pons,reticular formation and cerebellum the. Oldest parts of the brain and found in almost every species. Midbrain: small middle region of brain involved in processing visual and auditory processing.
