The influence of sleep deprivation on the contingent negative variation.
The physiological functions (contingent negative variation (CNV), critical nicker fusion frcyueney (CFF), oral temperature. blood pressure and heart rate) of five subjects were measured every three hours in 36-hour sleep deprivation and twice after the recovery night. The subjects 'Nere given tasks (UchidaKraepelin test. etc.) and were made to fill out a self-rating yuestionnaire of suhjective ...
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 کاملMotor and non-motor components of the Contingent Negative Variation.
To study the contribution of the Stimulus-Preceding Negativity (SPN) to the late wave of the Contingent Negative Variation (CNV), negativity was recorded preceding an instruction stimulus (S1), an instruction stimulus to which a motor response was required (S2) and a stimulus that transmitted Knowledge of Results (KR). All recorded negativities showed a centro-parietal maximum. The pre-instruct...
متن کاملThe magnetic counterpart of the contingent negative variation.
The magnetic counterpart of the CNV, the contingent magnetic variation (CMV), was investigated in an Go/No Go design: subjects moved their index finger to the offset of a 4 sec tone of a certain frequency in the Go condition and were asked not to move during presentation of a 4 sec tone of different frequency in the No Go condition. During the preparatory interval, both the CMV and the electric...
