Differential Go/NoGo activity in both contingent negative variation and spectral power. [PDF]

PLoS One, 2012
We investigated whether both the contingent negative variation (CNV), an event-related potential index of preparatory brain activity, and event-related oscillatory EEG activity differentiated Go and NoGo trials in a delayed response task.

Exploring the cortical habituation in migraine patients based on contingent negative variation. [PDF]

Front Neurol, 2023
IntroductionCognitive dysfunction has frequently been found in patients with migraine. The so-called contingent negative variation (CNV) and EEG power spectral densities may be the best choices to explore the underlining pathophysiology, such as cortical

Contingent negative variation as an evaluation indicator of neurocognitive disorder after traumatic brain injury. [PDF]

Front Psychiatry, 2023
IntroductionNeurocognitive disorders are commonly observed in patients suffering from traumatic brain injury (TBI). Methods to assess neurocognitive disorders have thus drawn the general attention of the public, especially electrophysiology parameter ...

Impulsivity Moderates the Effect of Neurofeedback Training on the Contingent Negative Variation in Autism Spectrum Disorder. [PDF]

Front Hum Neurosci, 2022
BackgroundThe contingent negative variation (CNV) is a well-studied indicator of attention- and expectancy-related processes in the human brain. An abnormal CNV amplitude has been found in diverse neurodevelopmental psychiatric disorders.

Abnormal Contingent Negative Variation Drifts During Facial Expression Judgment in Schizophrenia Patients. [PDF]

Front Hum Neurosci, 2020
Schizophrenia patients often show impaired facial expression recognition, which leads to difficulties in adaptation to daily life. However, it remains unclear whether the deficit is at the perceptual or higher cognitive level of facial emotion processing.

Relationship between Contingent Negative Variation and afterimage duration in migraine patients. [PDF]

Front Neurol
BackgroundAbnormalities in electrocortical parameters and persistence of afterimage after visual stimulation are known to occur in migraine patients. The results of studies on Contingent Negative Variation (CNV) and afterimage persistence in migraine ...

Unveiling the Role of Contingent Negative Variation (CNV) in Migraine: A Review of Electrophysiological Studies in Adults and Children. [PDF]

Biomedicines, 2023
Migraine has been considered a chronic neuronal-based pain disorder characterized by the presence of cortical hyperexcitability. The Contingent Negative Variation (CNV) is the most explored electrophysiological index in migraine.
