Perceived control over a gambling outcome leads individuals to accept more and larger bets, increased risk-taking. Pathological gamblers, however, do not diminish risk-taking when control is absent, suggesting an illusion of control. To evaluate neural correlates of perceived control in gamblers, this study compared magnetoencephalography responses of 36 pathological (PG) and 36 non-pathological gamblers (NPG) during the Georgia Gambling Task. PGs exhibited greater activity in bilateral primary… Expand
Pathological gamblers are more vulnerable to the illusion of control in a standard associative learning task
The results suggest that the experimental tasks used in basic associative learning research could be used to detect illusions of control in gamblers in a more indirect way, as compared to introspective and domain-specific questionnaires, and that in addition to gambling-specific problems, pathological gamblers may have a higher-than-normal illusion of Control in their daily life.

Cross-species approaches to pathological gambling: A review targeting sex differences, adolescent vulnerability and ecological validity of research tools
Three features of pathological gambling which hitherto have received relatively little attention are reviewed in humans and animals: sex differences in (the development of) pathological gambling, adolescence as a (putative) sensitive period for (developing) pathological betting and avenues for improving ecological validity of research tools.

Abnormalities of functional brain networks in pathological gambling: a graph-theoretical approach
It is made evident that PG is also associated with abnormalities in the topological network structure of the brain during rest, and these findings will be of relevance for understanding functional connectivity in other addictive disorders. Expand
Almost winning: Induced MEG theta power in insula and orbitofrontal cortex increases during gambling near-misses and is associated with BOLD signal and gambling severity
It is demonstrated that the near-miss effect in insula and OFC is associated with induced theta oscillations, and this theta-band activity was positively associated with gambling severity. Expand
Effects of Mood Induction and Bias-Inducing Contextual Cues on Decision Making in Gamblers and Healthy Individuals
Results showed that mood did not influence healthy participants; however, problem gamblers were more risk-seeking after negative mood induction, and bias-inducing contextual cues were found to be responsible for this. Expand
Features of Gambling Disorder and Internet Gaming Disorder in the spectrum of addictive disorders
It might be hard to imagine that a leisure activity could turn to suffering and mental disorder in need of treatment. Nevertheless, emergent behavioral addictions (BAs) such as gambling disorder (GD)Expand
Clinical Improvements in Comorbid Gambling/Cocaine Use Disorder (GD/CUD) Patients Undergoing Repetitive Transcranial Magnetic Stimulation (rTMS)
Income is provided into the potential role of rTMS as a therapeutic intervention for reducing both gambling and cocaine use in patients with a dual diagnosis of gambling disorder. Expand
A longitudinal study mapping changes in explicit and implicit measures of gambling behaviour
Gambling is a popular activity, both globally and in the UK, with the majority of adults engaging in some degree of gambling behaviour. Contemporary views of gambling behaviour, addiction andExpand
Non-invasive Brain Stimulation for Gambling Disorder: A Systematic Review
Most studies showed a reduction of gambling behavior, craving for gambling, and gambling-related symptoms and NIBS effects on psychiatric symptoms were less consistent. Expand
Psychosis subgroups differ in intrinsic neural activity but not task-specific processing
Differences in intrinsic neural activity may be a fundamental characteristic of psychosis and need to be evaluated separately from stimulus-specific responses, and grouping patients based on multidimensional classification using neurobiological data may have advantages for resolving heterogeneity and clarifying illness mechanisms relative to traditional psychiatric diagnoses.

Hypersensitivity to Reward in Problem Gamblers
The results suggest that high-risk-taking behavior in problem gamblers is associated with an increased reward-related neural response to infrequent successes of this behavior. Expand
Frontal lobe dysfunction in pathological gambling patients
The data seem to suggest the existence of a link between PG and other disorders all having diminished ability to evaluate future consequences, which may be explained at least in part by an abnormal functioning of the orbitofrontal cortex. Expand
Decision-making impairments in patients with pathological gambling
PG patients showed pronounced deficits in the Game of Dice Task, and the frequency of risky decisions was correlated with executive functions and feedback processing, suggesting risky decisions of PG patients might be influenced by both dorsolateral prefrontal and orbitofrontal cortex dysfunctions.

A Cognitive Neuroscience Approach to Studying the Role of Overconfidence in Problem Gambling
Confidence and overconfidence were explored using magnetoencephalography (MEG) to measure brain activity during a judgment task and matching and mismatching targets were associated with activity in the medial occipital cortex and left supramarginal gyrus, respectively. Expand
Gambling urges in pathological gambling: a functional magnetic resonance imaging study.
In men with PG, gambling cue presentation elicits gambling urges and leads to a temporally dynamic pattern of brain activity changes in frontal, paralimbic, and limbic brain structures. Expand

It is concluded that pathological and problem gamblers process information about confidence and control differently from non-problem gamblers. Expand
Prefrontal cortex activity is reduced in gambling and nongambling substance users during decision‐making
The results support a hypothesis that defects in ventral medial frontal processing lead to impaired decisions that involve risk and reductions in right prefrontal activity during decision‐making appear to be modulated by the presence of gambling problems. Expand
Diminished Frontostriatal Activity During Processing of Monetary Rewards and Losses in Pathological Gambling
Relatively decreased activity in corticostriatal neurocircuitsry during multiple phases of reward processing suggests consistent alterations in neurocircuitry underlying incentive valuation and loss prediction and may represent targets for treatment development in addictions. Expand
Cognitive Processes Associated with Gambling Behaviour
Gambling behaviours can be pathological if positive response is extreme, but very little is known about the psychological precursors of pathological gambling in Australia. This study examined theExpand
Cue-Induced Brain Activity in Pathological Gamblers
Findings in fMRI suggest a dissociation in visual processing stream may represent a component of cue-induced craving for gambling or conditioned behavior that could underlie pathological gambling. Expand
