Attention Reduction and Suppressed Direct-Current Potentials in the Human Brain
TLDR
Contingent negative variation and reaction time appear to reflect a common process, attention, which suppresses direct-current potentials recorded from the human scalp.
Brain wave components of the contingent negative variation in humans.
In a contingent negative variation paradigm with two stimuli paired at an interstimulus interval of 4 seconds, two distinct waveforms having functional and topographic differences are observed. An
Ready…Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time
A neuroimaging study reveals novel insights into how the brain responds to an anticipated event, such as a starting gun or responding to a green light.
The Effect of Motor‐Response‐Deprivation on Contingent Negative Variation (CNV) III: Relation with Maudsley Personality Inventory (MPI)
The contingent negative variation (CNV) was correlated with Maudsley Personality Inventory (MPI) in 43 healthy adults as follows:
Contingent negative variation: a biomarker of abnormal attention in functional movement disorders
TLDR
The aim was to ascertain whether the clinical improvement of functional movement disorders after physiotherapy would be associated with faster reaction times and modulation of contingent negative variation.
Brain-computer interfaces for communication and control
TLDR
The brain's electrical signals enable people without muscle control to physically interact with the world through the use of their brains' electrical signals.
Synthesis of the contingent negative variation brain potential from noncontingent stimulus and motor elements.
TLDR
Slow shifts in brain potential obtained during a warned reaction-time task were compared with waveforms synthesized by the addition of separately obtained potentials associated with individual (nonpaired) sensory stimuli and self-initiated motor movements, suggesting that the contingent negative variation is constituted largely of separate, noncontingent elements related to sensory and motor processes.
Beyond Reaction Time and Error Rate: Monitoring Mental Processes by Means of Slow Event-Related Brain Potentials
Slow event-related brain potentials, i.e. amplitude shifts which prevail for at least 200 msec in the EEG, seem to be of particular interest for cognitive psychology. Support for this claim comes
Electrophysiological Correlates of Meaning
TLDR
This approach revealed that late components of frontal, but not occipital, evoked potentials reflect the change of meaning of a symbolic stimulus when it appears in different temporal contexts.
Methylphenidate promotes the interaction between motor cortex facilitation and attention in healthy adults: A combined study using event‐related potentials and transcranial magnetic stimulation
This study investigated simultaneously the impact of methylphenidate (MPH) on the interaction of inhibitory and facilitative pathways in regions processing motor and cognitive functions.

Glomerular filtration after obstruction of the ureter
TLDR
This work has attempted to estimate, by a modification of the original stopflow procedure, how long and at what rate glomerular filtration will continue in the dog's kidney if its ureteric outflow is suddenly obstructed during intense osmotic diuresis.
