Document Summary

In living humans, cat scans or mris can be conducted to reveal changes in grey and white matter. Researchers can then infer from the properties of the collected light what regions in the brain were engaged by the task. The spatial location of the tracer molecule in the brain can be determined based on the emitted positrons. Understand which of these techniques are important for cognitive neuroscientists: describe the reasons for studying different nervous systems in animals other than human beings. Involved with taste experiences that originate from the tongue, pharynx, epiglottis, and so forth: wernicke"s area in temporal lobe, arcuate fasciculus: fiber tract that connects wernicke"s and broca"s speech areas, agnosia: due to damage of wernicke"s area. If we had all these unused brain, that is a lot of wasted energy (taking out a huge head of the vagina) Brain to body mass tissue the bigger the body, the more neurons needed to sustain it.
