Document Summary
Most direct way is to measure brain is electrical activity; electrical activity when neurons are firing action potentials (different concentrations of ions are changing) Haemodynamic don"t measure electrical activity directly, measures changes in blood flow and oxygenation of blood flow. Eye movement monitoring: can measure cognitive processes as they occur. When familiar with the face you look more at the eyes. Young people who have intact memories become more efficient in viewing faces. Example: study visiospatial memories; look at cognitive processes when learning memories, and matching. Healthy people will make eye movements back to the location of object 1 when they see object 2, older adults don"t do that trying to teach older adults this method to see if it can improve memory. Lecturer"s study correlation; people who looked back at locations that were studied did better and were more likely to get the trial correct. Ct provides info of grey matter but it"s low resolution, cheaper.
