Alpha oscillations in brain functioning: an integrative theoryE Basar
Institute of Physiology, Medical University Lubeck, Germany
Int J Psychophysiol 26:5-29. 1997..6) The major physiological meaning of 10-Hz oscillations may be comparable to the putative universal role of gamma responses in brain signaling...
The selectively distributed theta system: functionsE Basar
Institute of Physiology, Medical University Lubeck, Ratzeburger Allee 160, D 23538, Lubeck, Germany
Int J Psychophysiol 39:197-212. 2001....
Spontaneous EEG theta activity controls frontal visual evoked potential amplitudesE Basar
Institute of Physiology, Medical University Lubeck, Germany
Electroencephalogr Clin Neurophysiol 108:101-9. 1998..A sophisticated analysis of frontal EPs, mainly in the framework of cognitive studies, should consider the theta activity prior to stimulation...
Are cognitive processes manifested in event-related gamma, alpha, theta and delta oscillations in the EEG?E Basar
Institute of Physiology, Medical University Lubeck, Germany
Neurosci Lett 259:165-8. 1999..It is argued that selectively distributed delta, theta, alpha and gamma oscillatory systems act as resonant communication networks through large populations of neurons, with functional relations to memory and integrative functions...
Oscillatory brain dynamics, wavelet analysis, and cognitionE Basar
Institute of Physiology, Medical University Lubeck, Lubeck, Germany
Brain Lang 66:146-83. 1999..The results of frequency analysis as performed earlier were thus confirmed by wavelet analysis. This supports the view that ERP frequency components correspond to evoked rhythms with a distinct biological significance...
Brain oscillations in perception and memoryE Basar
Institute of Physiology, Medical University Lubeck, 23538, Lubeck, Germany
Int J Psychophysiol 35:95-124. 2000..Thus, oscillatory processes might play a major role in relation with memory and integrative functions. A new 'neurons-brain' doctrine is also proposed to extend the neuron doctrine of Sherrington...
Gamma, alpha, delta, and theta oscillations govern cognitive processesE Basar
Institute of Physiology, Medical University Lubeck, 23538, Lubeck, Germany
Int J Psychophysiol 39:241-8. 2001..Thus, oscillatory processes might play a major role in functional communication in the brain in relation to memory and integrative functions...
Selectively distributed gamma band system of the brainE Basar
Institute of Physiology, Medical University Lubeck, 23538, Lubeck, Germany
Int J Psychophysiol 39:129-35. 2001..These results support the hypothesis of a selectively distributed gamma system of the brain...
Event-related oscillations are 'real brain responses'--wavelet analysis and new strategiesE Basar
Institute of Physiology, Medical University Lubeck, Ratzeburger Allee 160, 23538, Lubeck, Germany
Int J Psychophysiol 39:91-127. 2001..The frequency components of the event-related potential vary independently of each other with respect to: (a) their relation to the event; (b) their topographic distribution; and (c) with the mode of the physiological measurements...
Is the alpha rhythm a control parameter for brain responses?E Basar
Institute of Physiology, Medical University of Lubeck, Germany
Biol Cybern 76:471-80. 1997..The results are discussed in the context of the diffuse and distributed alpha system of the brain. Age-dependent changes in frontal alpha activity are suggested to be related to frontal brain functioning during aging...
Alpha oscillations as an indicator of dynamic memory operations - anticipation of omitted stimuliI Maltseva
Institute of Physiology, Medical University of Lubeck, Ratzeburger Allee, 160, 23562, Luebeck, Germany
Int J Psychophysiol 36:185-97. 2000..A lack of topographical correspondence with results from a passive 'missing stimulus' paradigm underlines the specific intentional origin of the observed phase ordering. Theoretical implications of the results are discussed...
Alpha oscillations shed new light on relation between EEG and single neuronsM Schurmann
Institute of Physiology, Medical University Lubeck, Germany
Neurosci Res 33:79-80. 1999..Taking into account the role of such comparisons across levels for the interpretation of gamma oscillations, these data lend further support to the concept of functionally relevant alpha oscillations...
EEG responses to combined somatosensory and transcranial magnetic stimulationM Schurmann
Institute of Physiology, Medical University Lubeck, D 23538, Lubeck, Germany
Clin Neurophysiol 112:19-24. 2001..To investigate a possible interaction between sensory processing and transcranial magnetic stimulation (TMS), an experimental set-up permitting multichannel EEG measurements was used...
Bisensory stimulation increases gamma-responses over multiple cortical regionsO W Sakowitz
Institute of Physiology, Medical University Lubeck, 23538, Lubeck, Germany
Brain Res Cogn Brain Res 11:267-79. 2001..e. one of the steps between sensory transmission and perception. Our data may be interpreted as a further example of function-related gamma responses in the EEG...
Odor input generates approximately 1.5 Hz and approximately 3 Hz spectral peaks in the helix pedal ganglionA Schutt
Institute of Physiology, Medical University of Lubeck, Ratzeburger Allee 160, 23538, Lubeck, Germany
Brain Res 879:73-87. 2000....
