maging techniques such as Nuclear Magnetic Resonance or NMR, Positron Emission Tomography or PET, Single Photon Emission Tomography or SPECT and Magnetic Resonance Spectrography or MRS have contributed to understand the mechanisms of the different forms of perception, action, thinking, feeling, as well as of affective disorders. Each technique has its specificity and enables to “see” each phenomenon from different points of view. As a whole, these techniques give us some space-temporal indications: the type of structures, cell groups and also what and when single neurons activate, in which sequence during the performing of a task, under the action of a specific stimulus or when resting. Deviations from normality registered in standard conditions help us understand the site and the quality of the neuro-functional substrata involved in some disorders of the psychic sphere. In the present article the different investigation techniques and their applicative specificity are illustrated.
