Document Summary
Neuroimaging techniques: machines the monitor biochemical events in a serioes of digitally animated slices thru a persns brain, while a computer takes this info and constructs visual images to show which regions have been metabolically most active. Include pet, fmri: pics are constructed to show brain activity changing over time in the course, ex, of diff emotional states. Neuroscientists stimulated parts of the brain w electric currents or w magnetic fields & measured electric signals (eeg) or magnetic signals (meg) generated by populations of neurons. W these emthods, researchers have begun o discver the functions of regions of the brain. Medulla: regulates cardiovascular activity pons, controls leep and breathing cerebellum, motor coordination nd automatic movements. Forebrain thalamus: intergrating sensory info hippocampus, critical for memory processes hypothalamus, involved w important biological funcitions eating, sex beh, aggression, body temp limbic system, amygdala, cerebral cortex. Bc so large in humans, it ets out brains apart from other species.
