Contingent Negative Variation and Personality in Depression [PDF]

Neuropsychobiology, 2001
Contingent negative variation (CNV) has been applied in depression with controversial results. A major source for these controversial results could result from the diversity of depressed patients included in the different studies. Supporting this assumption, impulsivity, blunted affect and suicidal behavior significantly influence CNV amplitude ...

The magnetic counterpart of the contingent negative variation [PDF]

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1994
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.

Differences in Mechanical Parameters of Keyboard Switches Modulate Motor Preparation: A Wearable EEG Study

Frontiers in Neuroergonomics, 2021
The mechanical parameters of keyboard switches affect the psychological sense of pressing. The effects of different mechanical parameters on psychological sense have been quantified using questionnaires, but these subjective evaluations are unable to ...

The Electrocortical Signature of Successful and Unsuccessful Deception in a Face-to-Face Social Interaction

Frontiers in Human Neuroscience, 2020
Deceptive behavior, and the evaluation of others’ behavior as truthful or deceptive, are crucial aspects of human social interaction. We report a study investigating two participants in a social interaction, performing a deception task.

Contingent negative variation in epilepsy

Seizure, 1997
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.
