Document Summary

Module 6: tools of discovery and older brain structures. Having our heads examined (figure 6. 1-6. 3: scientists can selectively destroy or electrically, chemically, or magnetically stimulate the brain, eeg (electroencephalogram, pet (positron emission tomography, mri (magnetic resonance imaging) fmri (functional mri) Older brain structure: less complex brain in primitive vertebrates handle basic survival functions, more complex brain in advanced mammals (including humans) contain new brain systems built on the old. The brainstem, including the medulla and pons, is an extension of your spinal cord. The brainstem (figure 6. 5: the body"s cross-wiring, nerves from one side of the brain mostly linked to body"s opposite side, brainstem. Is oldest and innermost brain region: medulla. Is located at base of the brainstem; controls heartbeat and breathing: pons, sits above medulla and helps coordinate movement. Involves nerve network running through the brainstem and thalamus; plays an important role in controlling arousal: thalamus.
