uses x-ray beams (rotating) to generate a brain slice and digitally reconstruct the image
uses info on how hydrogen atoms respond in the brain to perturbations of a strong magnetic field
looking at the relationship between activity in certain brain areas and mental functions, ex: PET, fMRI, EEG, etc.
fMRI & PET
detect changes in blood flow & metabolism in the brain. Since ative neurons have more glucose & oxygen, there is more blood flow there.
Cell bodies in layers, surface layer separated from pia mater, apical dendrites form multiple branches
What are common features of the cortex?
separated from parietal lobe by post-central gyrus. Contains dopamine sensitive areas of cortex associated with reward, attention, long-term memory, planning, and drive.
integrates sensory info ffrom different areas
lobe involved in vision
lobe involved in auditory perception
outer layer of the cerebral hemispheres, made up of six layers labeled I to VI. Is part of the cerebral cortex. Involved in sensory perception, generation of motor commands, spatial reasoning, conscious thought, and language.
top layer of cerebral hemispheres in brain of mammals
Convex fold or elevation in surface of brain
grooves/trenches/fissures in brain
situated in the medial aspect of the cortex, includes cortex of cingulated gyrus, which lies immediately above corpus collosum.
