Brain imaging techniques Introduction to brain imaging techniques and other methods A number of techniques are available to investigate the question of how and where in the brain particular perceptual and cognitive processes occur. Tasks or tests can be devised that place varying levels of demand on the cognitive, sensory or motor capacities of the participant being tested. Performance of these tasks is then correlated with physiological measurements, and on the basis of these results, we may go
