PSYC31H3 Chapter Notes - Chapter 2: Magnetic Resonance Imaging, Implicit Memory, Electrodermal Activity
Document Summary
Neurological examinations includes extensive study of brain"s chief product behaviour. Neurologist studies person"s strength, efficiency, reactivity, and appropriateness of their responses to commands, questions, discrete stimulation of particular neural subsystems, and challenges to specific muscle groups and motor patterns. Neurologist also examines body structures, looking for such evidence of brain dysfunction as welling of retina/atrophied muscles due to insufficient neural stimulation. Scanning techniques began in mid 1970s imaging has become critical for diagnosis. Can show quantified data brain mapping. Npa another way to study brain via behavioural product. Direct observation is impossible, but goals are set out for this to happen. Newer techniques rely on indirect, typically non-invasive methods also used by cognitive neuroscientists and np"ists to examine correlates of behaviour in both patient and healthy populations. Earliest instrument used to measure brain function and still used are electrophysiological. Has recognition in absence of conscious perception: er/erps demonstrate hemispheric specializations; processing speed and efficiency.
