Research Methods of Biopsychology

The video explores various research methods in biopsychology, focusing on brain imaging techniques like CT, PET, MRI, and fMRI, as well as methods for recording psychophysiological data such as EEG and MEG. It also covers direct brain manipulation techniques, including stereotaxic surgery and optogenetics, and concludes with behavioral experiments that assess cognitive functions and behaviors in humans and animals.
