Co-operation in the Brain in Higher Cognitive Functioning
We have analyzed the interdependencies between different regions of human brain during processing of different kinds of music by using multivariate EEG signals. In this study, a recent index, called similarity in...

EEG studies in the perception of simple and complex rhythms
The concept of a beat, a musical pulse underlying any melody, is fundamental to any kind of music; in the most primitive civilizations, it is even the predominant musical quality. The eminent role of rhythm in...

The Information Content of the Human EEG
The field potentials recorded by the EEG emerge from cooperative processes and are commonly explained by “synchronization”, a still poorley understood inherent feature of the nervous system. Several properties of...

Probability Map** of EEG Changes due to the Perception of Music
When our studies on the EEG during cognition were begun a few years ago, the main question was whether the spontaneous EEG contains any information about cognitive processes or, rather, would turn out as a sor...

Approaching the Generators of the Eeg: Intracortical Recordings of Field Potentials
Clinical electroencephalographic (EEG) records from the surface of the scalp represent only a small part of the electrical activities which are generated in the cortex. This is due to attenuations and distorti...

Paroxysmal neuronal depolarizations in the rat motor cortex in vivo: intracellular injection of the calcium agonist BAY K 8644
Epileptic activity was elicited in the rat's motor cortex by local application of penicillin. At the neuronal level it consisted of typical paroxysmal depolarization shifts. The calcium agonist BAY K 8644 was ...
