Frequently studied ERP components include P1, N1, P2, N2, P3 (P300), N4 (N400), mismatch negativity (MMN), contingent negative variation (CNV), and bereitschaftspotential (BP) or readiness potential.
Using a mock-crime design, the current study (n = 20) investigated the effects of deception on the Contingent Negative Variation (CNV), the Lateralized Readiness Potential (LRP), the Correct Response Negativity (CRN), and the stimulus-locked N200 and P300 components.
Patterns of EEG coherence, power, and contingent negative variation characterize the integration of transcendental and waking states.
The contingent negative variation (CNV) is a slow negative shift in the electroencephalogram (EEG), observed during response preparation.
Walter, W. G., Cooper, R., Aldridge, V. J., McCallum, W. C. & Winter, A. L. Contingent negative variation: an electric sign of sensori-motor association and expectancy in the human brain.
In EEG research, the contingent negative variation (CNV) is considered to be strongly related to interval timing (e.g., Macar & Vidal, 2004; Macar, Vidal, & Casini, 1999).
Even the very simple stereotypic movements used to study the 'contingent negative variation' and the 'readiness potential' begin with EEG indicative of widely distributed brain activity.
The contingent negative variation (CNV), onset time of electromyographic activity in leading limb muscles and center of pressure (COP) trajectory in the anticipatory phase of GI were measured.
We analyzed evoked EEG single-trial variability, contingent negative variation (CNV), and pre-stimulus alpha power with respect to the expert vs. novice groups.
The contingent negative variation of the EEG differentiated between CS+ and CS− in the healthy controls but not the chronic pain patients.
He immediately was able to demonstrate that this phenomenon of "negative variation" also occurs in striated muscle and is the primary cause of muscular contraction.
