CNV (Contingent Negative Variation) in Neurosurgical Patients
Since the first description of CNV (contingent negative variation) by Walter in 1964, many reports on this phenomenon have appeared, mainly in the psychiatric field. In this report, CNV was recorded in neurosurgical patients under three experimental conditions which differed as to the level of difficulty in concentrating on the conditioned tasks. Under the 1st condition, CNV was recorded withou...
متن کاملContingent negative variation (CNV) associated with sensorimotor timing error correction
INTRODUCTION Detection and subsequent correction of sensorimotor timing errors are fundamental to adaptive behavior. Using scalp-recorded event-related potentials (ERPs), we sought to find ERP components that are predictive of error correction performance during rhythmic movements. METHOD Healthy right-handed participants were asked to synchronize their finger taps to a regular tone sequence ...
متن کاملThe contingent negative variation (CNV): timing isn’t everything
When participants time intervals ranging from several hundred milliseconds to several seconds a negative polarity waveform, known as the contingent negative variation (CNV), manifests in the ongoing electroencephalogram (EEG). The perceptual and cognitive functions underlying this component are subject to ongoing debate. Moreover, recent evidence suggests that the link between the CNV and behav...
متن کاملTask related changes in contingent negative variation (CNV) response of endogenous evoked potentials.
Contingent negative variation (CNV) is a slow negative cortical potential shift, which occurs during a warned foreperiod reaction time paradigm. Most studies of evoked potentials have concentrated on components occurring during the first 300 msec, although there are important and recordable aspects of signal processing occurring well beyond 300 msec e.g. late negative slow wave. CNV has proven ...
متن کاملContingent negative variation in epilepsy
The contingent negative variation (CNV) is a long-latency event-related potential elicited by paired or associated stimuli. We recorded contingent negative variation in 50 patients with complex partial and secondarily generalized seizures and in 20 neurologically and psychiatrically normal unmedicated controls. CNV was recorded from Fz, Cz, and Pz. A 2000 Hz tone was followed after 1.5 s by 100...
