The research methods of biopsychology Methods of visualizing the living human brain Contrast X-rays – inject something that absorbs X-rays less or more than surrounding tissue X-ray computed tomography (CT): 2-D images combined to create a 3-D image Magnetic resonance imaging (MRI): Produces 2-D & 3-D images with high spatial resolution Positron emission tomography (PET) Magnetotoencephalography (MEG): Provides higher temporal resolution of brain activity changes than fMRI Brain image achives: Allows researchers to share their raw data Transcranial magnetic stimulation (TMS): Disrupts brain activity to observe effects on consciousness-allows causal interference Advantages of MRI over PET Nothing injected Better spatial resolution Can create 3-D images of activity over the entire brain Recording human psychophysiological activity Recording from the body surface Electroencephalography Muscle tension Eye movement Skin conductance Cardiovascular activity EEG – Measuring brain waves
