Document Summary
Structural neuroimaging: provides highly detailed images of anatomical features of the brain. Functional neuroimaging: provides an indication of brain activity. In general, fmri is the most commonly used. Compares healthy older adults with those with pathological disorders of the brain. Links measures of cognitive performance to measures of brain structure or functioning. Links functional brain activity with cognitive behavioral data. Neurons consist of dendrites, axon, neuro-fibers and terminal branches. Neuroanatomy: the study of the brain, including the: These changes occur in greater numbers in diseases such as. Dopamine is associated with higher-level cognitive functioning, so declines are related to poorer: Tasks that require higher-level cognitive functioning like inhibiting thoughts, attention and planning. Abnormal processing of serotonin has been shown to be related to cognitive decline. Damage to structures that use acetylcholine is associated with memory declines. Especially in prefrontal cortex, hippocampus, and cerebellum. Provides index of density or structural health of the white matter.
