The Temporal sTrucTure of ongoing brain acTiviTy
brain and functional MRI. The latter has been informative due to its superb localizing power and its exquisite capability to record the dynamics of neuronal population activity across the entire brain and to hence capture large-scale functional connectivity patterns. Yet, for instance when addressing temporal properties as below, limitations of hemodynamic signals will lead us to also discuss e...
متن کاملIntrinsic Coupling Modes: Multiscale Interactions in Ongoing Brain Activity
Intrinsic coupling constitutes a key feature of ongoing brain activity, which exhibits rich spatiotemporal patterning and contains information that influences cognitive processing. We discuss evidence for two distinct types of intrinsic coupling modes which seem to reflect the operation of different coupling mechanisms. One type arises from phase coupling of band-limited oscillatory signals, wh...
متن کاملRhythmic Pulsing: Linking Ongoing Brain Activity with Evoked Responses
The conventional assumption in human cognitive electrophysiology using EEG and MEG is that the presentation of a particular event such as visual or auditory stimuli evokes a "turning on" of additional brain activity that adds to the ongoing background activity. Averaging multiple event-locked trials is thought to result in the cancellation of the seemingly random phased ongoing activity while l...
متن کاملSpatial-temporal characteristics of perceptual organization following acquired brain injury.
OBJECTIVE To assess characteristics of perceptual organization following brain injury. RESEARCH DESIGN A repeated measures between groups design. METHODS Perceptual thresholds were compared between 10 persons with brain injury and 10 demographically matched healthy control subjects. Ten young control subjects were also tested to evaluate effects of normal ageing on these processes. Particip...
متن کاملTemporal organization of the brain: Neurocognitive mechanisms and clinical implications.
The synchrony between the individual brain and its environment is maintained by a system of internal clocks that together reflect the temporal organization of the organism. Extending the theoretical work of Edelman and others, the temporal organization of the brain is posited as functioning through "re-entry" and "temporal tagging" and binds the wide range of possible times to a unified cogniti...
