Phase Locking of Oscillatory Responses — An Informative Approach for Studying Evoked Brain Activity procedure is based on the statement that phase-locked EEG activity reflects important information about signal processing by the brain. Therefore, our goal was to decompose single EEG sweeps into oscillatory components and to quantify the phase relationships independently from the amplitude charact

Correlation Between Unit Activity and Activity of Neural Populationseurons in the visual cortex activated by the same object in the world tend to discharge rhythmically and in unison. Such a one-noted neural harmony could in principle at least provide the neurons at higher cortical levels with stronger inputs so that they associate the activities of lower-order neur

Brain Response Susceptibilitys studied the relation of visual evoked potentials to EEG by comparing the power spectra of the spontaneous activity with the driven rhythmic activity of the brain. They have found that the occipital recording of a relaxed human subject displays a rhythmic spontaneous activity prior to photic flicke

The Evoked Potential Manifests a Superposition of Event-Related Oscillationsalgorithm based on selection of single sweeps by utilization of the enhancement factor described in Chap. 4. Basically, the present chapter contains examples describing evoked potentials with homogeneous frequency response or real oscillations similar to those in chapter 18. Accordingly, the present
