Gambling disorder is the first behavioral addiction recognized in the DSM-5. This marks the growing realization that both behavioral and substance-related addictions are manifestations of an 'addicted brain', displaying similar altered neurophysiological mechanisms. A decreased electrophysiological visual P300 is considered a hallmark effect of substance-related addictions, but has not yet been shown in behavioral addictions.

Visual evoked potentials (VEPs) can be measured in the EEG as response to a visual stimulus. Commonly, VEPs are displayed by averaging multiple responses to a certain stimulus or a classifier is train...
Visual information processing contains two opposite needs. There is both a need to comprehend the richness of the visual world and a need to extract only pertinent visual information to guide thoughts...
There is much evidence that neural activity in the human brain is modulated by task difficulty, particularly in visual, frontal, and parietal cortices. However, some basic psychophysical tasks in visu...
Recent theoretical frameworks have hypothesized that autism spectrum disorder (ASD) may be marked by an altered balance between sensory inputs and prior knowledge-the so-called hypoprior hypothesis. Y...
The ability to constantly anticipate events in the world is critical to human survival. It has been suggested that predictive processing originates from the motor system and that incoming sensory inpu...
This study examines the effect of regular naltrexone dosing on disordered gamblers. Gamblers will also be scanned pre- and post-treatment where we will investigate the functional changes t...
Pathological gambling is serious problem, with significant psychological, financial, and public health consequences. Nevertheless, controlled trials examining the efficacy of therapeutic i...
Many problem gamblers are also problem drinkers,with lifetime prevalence in nationally representative samples ranging from 45% to 73%. Heavy drinking often occurs while problem gamblers ar...
The purpose of the study is to examine whether problem gamblers who receive therapy calls in addition to a self-help manual will be more likely to quit or cut back on their gambling when c...
The objective of this application is to examine whether, given its mechanism of action, the dietary supplement, N-acetyl cysteine (NAC) will reduce both tobacco use and pathological gamble...
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
The electric response evoked in the cerebral cortex by visual stimulation or stimulation of the visual pathways.
Differential response to different stimuli.
Adjustment of BRAIN WAVES from two or more neuronal groups within or across a brain structure (e.g., cortical and limbic brain structures) to become uniform in EEG oscillation patterns in response to a stimulus. It is interpreted as a brain integration sign during many processes such as learning, memory, and perception and involves reciprocal neural connections.
A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry.
Psychiatry is the study of mental disorders and their diagnosis, management and prevention. Conditions include schizophrenia, severe depression and panic disorders among others. There are pharmaceutical treatments as well as other therapies to help...
