Neuropsychology is a branch of clinical psychology that studies how the brain and nervous system affect how we function on a daily basis. age and sex and they were screened for their physical and mental health. Therefore we have to be careful in making cause and effect The controls Its purpose is to show the functioning and structures of tissues and organs. Invasive or Non-Invasive: An advantage of fMRI is that is non-invasive. The images can clearly show the part of the body being investigated, including any abnormal areas, and can highlight how well certain functions of the body are working. & of course, those marked as metabolic uptake brighter than 2.7 are the ones that cause the heart-ache. The x-rays pass through tissues of different densities at different rates, allowing a computer to construct an overall image of the area of the body being scanned. This works because active neurons use glucose as fuel. Found inside – Page 30Evaluation of working memory Although working memory is one of the most recent ...
