PS101 Lecture Notes - Lecture 3: Functional Magnetic Resonance Imaging, Human Brain, Posttraumatic Stress Disorder
Document Summary
Biological psychology: an interdisciplinary field of study combing the methods and theories of psychology with those if biology, physiology biochemistry, and the neurosciences. Reciprocity of biology and experience: athletes as well as fans of a winning team tend to experience a raise in testosterone levels. Reductionism: our behaviour can be reduced to a simple process (neuron functioning) Methods in biological psychology: the recording and imaging of brain activity opened whole new areas of inquiry to biological psychologists, electroencephalography (eeg) Sensors placed on the scalp measure electrical activity in the brain, looking at amplitude and duration of brain waves. Mri (not tested on: uses magnets, scans and builds a 2-d or 3-d image, very clear image, distinguishes among different body tissues, need to avoid all mental objects, measures brain structure. Ct scan: x-ray type images may require dye to see what part of brain is activated, measures brain structures.
