Visual information processing in dyslexic children.

OBJECTIVE Several studies presented evidence for magnocellular deficits in dyslexics both in behavioural as well as in electrophysiological data of local electrode sites. We investigated two well-known paradigms (motion-onset and random-dot-kinematogram) with regard to global electrophysiological parameters. METHODS Twenty-one-channel event-related potentials (ERPs) of 16 dyslectic and 15 con...

Reference values in concentric needle electrode studies.

A recommendation of considerable concern is that different cutoff limits be used ‘‘depending on the clinical purpose’’. The electromyographer must report the results objectively and distinguish clearly between the results of electrophysiologic testing and conclusions based on other factors. There should only be one cutoff value, but the ultimate interpretation should take into account clinical ...

Modulation of brain criticality via suppression of EEG long-range temporal correlations (LRTCs) in a closed-loop neurofeedback stimulation.

EEG-defined functional microstates as basic building blocks of mental processes.

Electroencephalographic recording during transcranial magnetic stimulation in humans and animals.

OBJECTIVE We report on the development of an EEG recording system, comprised of electrodes and amplifiers that are compatible with TMS (single and rapid-rate) in both human and animal studies. METHODS We assembled a versatile multi-channel EEG recording system consisting of: (1) two types of electrodes that are safe during TMS or rTMS. (2) Low slew-rate EEG amplifiers that recover within a fe...
