Abstract

Magnetoencephalography: A new methodology for the study of basic
cognitive processes. Magnetoencephalography is a functional neuroimaging
technique that enables the description of the temporal and spatial
patterns of brain activity related with different basic cognitive
processes. Here we describe the main findings regarding functions such
as memory, language, perception, and executive functions, obtained by
means of the registration of the magnetic fields of the brain.
Magnetoencephalographic studies show that: (1) the effects found in
different tasks always occur in specific temporal windows; (2) the kind
of processing modulates the activation of different neural nets, and
therefore, brain activity is not completely determined by the type of
material; (3) biomagnetic and behavioural measures are complementary in
the study of human cognition. A critical point of view is offered
regarding the use of functional neuroimaging techniques. Additionally, a
three-dimensional perspective in cognitive research is suggested, in
which time, space, and frequency are the parameters used to study the
signals of cognition.
