Document Summary

Module 5: tools of discovery and older brain structures. By looking at the structure and activity of the brain: cat, ari, fmri, and pet scans: we can find what happens when parts of the brain is damaged or otherwise unable to work properly. Phineas gage: brain damage to the frontal lobe. We know that the frontal lobe is in control of the personality and decision making. Parts of the brain, and even neurons can be stimulated electrically, chemically or magnetically: this can result in behaviors such as giggling, head turning, or simulated vivid recall.
