PSYB57H3 Lecture Notes - Lecture 2: Developmental Cognitive Neuroscience, Cognitive Neuroscience, Cultural Neuroscience
Document Summary
Significant challenges to using brain-injury studies: we don"t know exactly how well that person functioned before the injury. Ct and mri: ct scans are great butt have radioactive affects mri imaging is optimal for getting still images of the brain (you can take an image in 90s!). It"s limitation is that it can only take still images. Pet scanning: use of radioactive isotopes to measure in vivo levels of glucose, neurotransmitters, etc . Fmri: measure changes in cerebral blood flow to examine task-induced fluctuations in neural activity. Cognitive psychology and neuroscience: an important coming together. Cognitive psychologists provide us with models to characterize stages of information processing, informed by behavioural analyses, educated inferences and more. Realistic models can then be evaluated using a variety of neuroimaging techniques to examine biological plausibility. Developmental cognitive neuroscience: both early and late-life approaches, infantile amnesia: long term memory isn"t activated until around age 2 we don"t remember anything before 2 yrs old.
