Document Summary

Techniques for visualizing the structural and functional characteristics of the human nervous system (in vitro, in vivo). Neuropsychology relies on expertise from physics, electronics, computer science, anatomy and physiology, medicine to achieve this . Structural neuroimaging permits visualization of neural structures. Functional neuroimaging maps physiologic states onto ns structures (and links them via behaviour ) Invasive vs. non-invasive neuroimaging (aka brain mapping ) Invasive neuroimaging: techniques that change the characteristics of the nervous tissue under study. E. g. , histologic techniques requiring tissue fixation, slicing and staining, functional neuroimaging using long-life radioisotopes ( c14deoxyglucose brain mapping, etc. ) Non-invasive neuroimaging: techniques that do not cause changes to the characteristics of the nervous tissue under study. E. g. , mri, fmri, pet, spect, eeg, meg, optical (nir) A transformation of a numerical scale (nominal, ordinal, interval, ratio) to a colour scale . 4-dimensional data visualization (3d + time ) with a pseudo-colour mapping function . Functional neuroimaging: imaging the activity of the nervous system.
