Document Summary

The brain imaging technique that reads the amount of glucose consumed by neurons & generates images of patterns of brain activity is the: eeg recording, ct scan, pet scan, mri, fmri. Of glia cell maintaining structure and support cells. Action potential - +40mv, has to receive a stimulus. Refractory period 1/1000th of a second, time when it cannot fire another action potential. Temporal summation summing something up over time *look up* Brain stem ( older structures) shared with other lower-order animals: controls basic psychological survival processes (breathing, heart rate) More recently evolved structures (cerebrum) are built atop structures from our distant evolutionary past. Development (embryo) progresses in the same order: involved in thinking, reasoning. More recently evolved structures (eg cerebellum) develop later. Where cord enters the brain it enlarges to form the stalk-like structure of the brainstem. Nerve relay between spinal cord & brain. Nerve relay between higher & lower levels of the nervous system.
