Contingent 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 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...
متن کاملCNV (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 کاملA study of contingent negative variation and post-imperative negative variation: search for state and trait electrophysiological markers in schizophrenia.
OBJECTIVE To compare event-related potential measures, contingent negative variation and post-imperative negative variation in drug-naïve or drug-free schizophrenic patients and normal healthy controls, and to study the effect of antipsychotic medication on the above measures. METHODS A hospital-based prospective study was conducted at Central Institute of Psychiatry, Ranchi, India. The sampl...
