Slow brain potentials in a visual-spatial memory task: topographic distribution and inter-laboratory consistency.
Slow brain electrical potentials (SPs) were investigated in a visual-spatialmemory task. Two issues were addressed: (1) the nature and topographic distribution of the potentials obtained under such conditions; and (2) the consistency of the SPs when recorded in six identically configured laboratories. Fifteen young male subjects were studied at each laboratory (total n = 90). The paradigm entai...
متن کاملMemory performance and area-specific self-regulation of slow cortical potentials: dual-task interference.
We examined the effect of area-specific feedback for slow potentials on sensorimotor and memory performance under single and dual-task conditions. Subjects observed a memory set for 400 ms and then determined 5 s later whether a target letter had been contained in the original presentation (Sternberg task). After one session of Sternberg-only training, feedback training was added for production...
متن کاملBrain activity preceding a 2D manual catching task
We investigated the event-related desynchronization (ERD) and synchronization (ERS) properties of cortical EEG rhythms in regions of interest (ROI) during the preparation of a 2D task for manual catching of a moving object. EEG signals were recorded through a 32-channel system in eleven healthy subjects during the interception task consisting of 2D catching with the right hand of a handle movin...
متن کاملFrequency and phase characteristics of slow cortical potentials preceding bimanual coordination.
The aim of the present study was to derive quantities which relate behavioral and neurophysiological levels of observation during a bimanual coordination task. We recorded the scalp electroencephalographic (EEG) signal preceding a sequence of 4 bimanual finger flexions of varying response rates in 12 subjects. A slow negative-going Bereitschaftspotential (BP) displayed larger mean amplitudes an...
متن کاملVery Slow Brain Potentials Relating to Expectancy: the CNV
S INCE THE publication by W. 6. Walter and his colleagues (1964), in which the contingent negative variation (ICNV) was initially reported, there has been a steady growth of interest in this phenomenon. Grey Walter's findings were confirmed and extended in several laboratories. The clinical applications of such techniques are now being explored. Dr. Walter's group reported that the effect consi...
