[The role of cortical oscillatory activity in information processing mechanisms].
BACKGROUND
Cortical oscillatory activity has been related recently to information processing mechanisms. Synchronization between different neuronal groups can explain how he different features of an object can be integrated into a single perception (binding), or how different muscular groups can be co-ordinated into a single movement.


METHODS
This paper reviews the knowledge up to date on the role of cortical oscillatory activity in perceptive binding and motor control. Also, the participation of alterations in cortical oscillatory activity in different neurological diseases (epilepsy, Parkinson's disease) is proposed, basing on available data.


CONCLUSIONS
The study of the changes in cortical oscillatory activity (specially in the so-called gamma band 30-60 Hz) can contribute to current knowledge on the physiology and pathophysiology of the different cortical areas involved in perceptive and motor tasks.
