Document Summary
Apa citation: clelland et al. (2009) or (clelland et al. , 2009) Rather than proved, use found evidence/correlations for/against, . Report result for each manipulation and task, be specific. Human neuro methods for measuring the brain (somatic intervention) are measured based on criteria of spatial, temporal, invasiveness. Function/metabolic activity, bold signal w/ oxygen atoms. Oxygenated blood has a different magnetic signature than deoxygenated blood, fmri is sensitive to this difference, allowing researchers to track the relative amount of oxygenated blood over time w/i a small brain region. Changes ratio of de/oxygenated blood, examine molecular spin. Indirect measure of brain activity - correlate of blood flow, which is a correlate of neurodynamics, good first step, looking at inputs to brain area (ipsp/epsp) rather than actual brain activity. Neurons require a constant supply of fresh oxygen to keep processes going. +: noninvasive/safe, repeatable, allows data to be collected across the entire brain simultaneously, good spatial resolution.
