REVOLUTIE IN NEUROPSIHOLOGIE
ABSTRACT
The
flowering of neuropsychology research within cognitive science has been accelerated by the
development of new methods for observing the working brain. The goal ofthepresentpaper is to
show tbat localized'paterns ofactivity during cognition can now be observed in
the intact or damaged brain using methods such as: Computer Tomography, CT; Magnetic
Resonance Imaging, MRI; Cerebral Blood Flow, CRB; Positrion Emision Tomography, PET. An introduction to
technical and methodological aspects of these techniques and selected examples of
applications in Cognitive Science will be presented. Although their spatia! and temporal
resolution is limited, these methods alow researchers to observe directely some of
what must be infered in the traditional method of correlating cognitive
performance with the locations of brain lesions.
Keywords: cognitive neurosciences, brain imagery, methods - CT, MRI, CRB, PET.
