Non-invasive brain stimulation techniques in the study of intuition

the growing use of brain stimulation in basic research and in clinical appli- cations reflects its capabilities to modulate cerebral function in ways not feasible with other techniques (Peterchev et al., 2012). brain-stimulation equipment allows investigators to test causal connections, not only cor- relations (as is the case with the usual electrophysiological and brain imagery methods), between given neural structures and the corresponding mental functions. although a direct correspondence between intuition processes and specific cortical areas has not been established yet, indirect evidence can be drawn by observing the effects of the decrease/increase of neural excitability in neural structures that are connected with the mental processes of deliberation and analysis (krawczyk, 2002), which, according to dualistic models, can be considered as the antagonists of intuition. In this chapter we aim to describe the various available techniques and their suitability to study intuition
