PSC 162 Chapter Notes - Chapter 8: Living Brain, Radioactive Tracer, Positron Emission Tomography
Document Summary
Psc 162: personality puzzle ch. 8- the anatomy and physiology of personality. Thalamus: regulates arousal and serves other functions. Hormones: biological chemicals that affect the entire body. Amygdala: has an important role in emotion. Cortex (cerebral cortex): wrapped around the inner organs of the brain. Neocortex: the outermost layer of the brain. Frontal cortex: crucial for uniquely human aspects of cognition (two frontal lobes) Brain damage: the oldest source of knowledge about the brain is the study of people who have suffered head injuries. Researchers will deliberately damage brains, perform surgery and lesion parts of the brains of animals such as rats, dogs and monkeys. Knowledge about animal brains is relevant to understanding human brains. Brain stimulation: stimulating parts of the brain directly using electrodes. Most of this research is done on animals. Transcranial magnetic stimulation (tms): uses rapidly changing magnetic fields to temporarily knock out areas of brain activity (virtual lesion)
