Driven and synchronized brain activities in the alpha band: A neuromagnetic test for frequency responsiveness

Journal/Book: Int J Psychophysiol. 1997; 26: PO Box 211, 1000 AE Amsterdam, Netherlands. Elsevier Science BV. 137-148.

Abstract: A new procedure to study cortical rhythmical activity, which includes stimulation paradigm, data analysis, and data presentation, is proposed. It enhances several features of the rhythmical responses while allowing for very short measurement sessions. This procedure permits us to classify activities within the frequency window studied on the basis of their responsiveness to scanned rhythmical stimulation. It can be used to recognize functional and pathological indicators linked to such activities. When used in conjunction with the identification of functional correlates of the same activities, it may bring useful information for their modelling.
