Affect-Related Brain Activity and Adolescent Substance Use: a Systematic Review
AbstractPurpose of ReviewThis review aims to summarize the research on brain activity during affective processing (i.e., reward, negative emotional stimuli, loss) and adolescent substance use (SU).Recent FindingsMost research revealed links between altered neural activity in midcingulo-insular, frontoparietal and other network regions and adolescent SU. Increased recruitment of midcingulo-insular regions —particularly the striatum —to positive affective stimuli (e.g., monetary reward) was most often associated with initiation and low-level use of substances, whereas decreased recruitment of these regions was most often...

Interactions of Emotion and Memory in the Aging Brain: Neural and Psychological Correlates
AbstractPurpose of ReviewThis review aims to summarize current research on the psychological and neural substrates of emotion and memory in aging.Recent FindingsEmotional memory remains largely intact with age; however, there are mixed findings regarding what type of information is preserved. Shifts in functional connectivity in the medial temporal lobe (MTL) and frontal cortex may underlie emotional memory alterations in aging and are particularly vulnerable to age-related disorders. However, we may be able to harness the interaction between emotion and memory to alleviate memory dysfunction in late life.SummaryThe relati...

Immersion in Substance-Related and Behavioural Addictions: Neural Systems and Neurochemical Substrates
AbstractPurpose of ReviewProblematic engagement in slot machine gambling has been linked to a state of immersion: heightened attention on the activity (i.e., gambling) at the expense of other mental processing. This review considers the relevance of this state to substance-related addictions, and other behavioural addictions besides disordered gambling. We further evaluate current knowledge on the neural systems and neurochemical substrates implicated in immersion.Recent FindingsPrior research has primarily considered immersive experiences from a lens of either dissociation (clinical symptoms indicating detachment from rea...

A Future of Current Flow Modelling for Transcranial Electrical Stimulation?
AbstractPurpose of ReviewTranscranial electrical stimulation (tES) is used to non-invasively modulate brain activity in health and disease. Current flow modeling (CFM) provides estimates of where and how much electrical current is delivered to in the brain during tES. It therefore holds promise as a method to reduce commonplace variability in tES delivery and, in turn, the outcomes of stimulation. However, the adoption of CFM has not yet been widespread and its impact on tES outcome variability is unclear. Here, we discuss the potential barriers to effective, practical CFM-informed tES use.Recent Fi...

The Neurocognitive Effects of Cannabis Across the Lifespan
AbstractPurpose of ReviewThis review examines the neurocognitive effects of cannabis and relevant developmental factors across adolescence (age 13 –21), adulthood (21–65), and older adulthood (65 +).Recent FindingsCannabis use is robustly associated with poorer neurocognitive functioning; however, studies that carefully control for confounds have often not found any evidence for impairment. Notably, the endocannabinoid system may underly how cannabis use affects neurocognitive functions, including heightened vulnerability during adolescence. In contrast, the endocannabinoid system may underlie protective neurocogniti...

Neural and Behavioral Correlates of Impaired Insight and Self-awareness in Substance Use Disorder
AbstractPurpose of ReviewClinical insight is an emerging interest in substance use disorder research, but is difficult to study empirically. We reviewed recent research examining the behavioral and neural correlates of several psychological processes tapping into self-awareness that may in turn contribute to insight.Recent FindingsIndividuals with substance use disorder exhibit deficits in self-monitoring (especially self-report/behavior dissociations), metacognition, alexithymia, readiness for behavior change, and interoception. Behavioral impairments have been further linked to neural abnormalities in a diverse network o...

Racial Disparities in the Treatment of Schizophrenia Spectrum Disorders: How Far Have We Come?
AbstractPurpose of ReviewThis paper reviews the literature examining antipsychotic prescription disparities between white people and black people.Recent FindingsDespite literature documenting racial discrepancies in diagnosis, there have been limited studies examining disparities in antipsychotic prescription between white people and black people. Studies have demonstrated that black people are more likely to receive first generation antipsychotics, higher antipsychotic doses, and long acting injectables, but less likely to receive clozapine. Much of this work was done in the early 2000s.SummaryFuture research directions i...

COVID-19 and Psychotic Symptoms: the View from Psychiatric Immunology
AbstractPurpose of ReviewTo explore the immunological underpinnings of psychosis in the COVID-19 patients.Recent FindingsCOVID-19 pandemic led to a surge in psychiatric morbidities, including psychosis. Various putative biological and psychosocial changes have been implicated in COVID-19-related psychosis. COVID-19 is a proinflammatory state. Alterations in immunological processes both as a direct consequence of infection or secondary to the hyperimmune response heuristically explain the etiopathogenesis of psychosis in the affected individual. The uses of immunosuppressant and immunomodulatory drugs may be the other moder...

The Impact of Context on EEG Motor Imagery Neurofeedback and Related Motor Domains
AbstractNeurofeedback (NF) is a versatile non-invasive neuromodulation technique. In combination with motor imagery (MI), NF has considerable potential for enhancing motor performance or supplementing motor rehabilitation. However, not all users achieve reliable NF control. While research has focused on various brain signal properties and the optimisation of signal processing to solve this issue, the impact of context, i.e. the conditions in which NF motor tasks occur, is comparatively unknown. We review current research on the impact of context on MI NF and related motor domains. We identify long-term factors that act at ...

Neuropsychological Constructs in Gaming Disorders: a Systematic Review
DiscussionChanges in neurocognitive features in IGD are similar to substance use disorders and gambling disorder, suggesting the pathology may develop by similar mechanisms. Counterintuitively, the improved performance in non-IGD gaming populations in some studies suggests that video game experience itself, distinct from addiction towards games, may improve performance in error processing and reaction times. Future research incorporating IGD comorbidities, longitudinal designs to establish causality, and standard diagnostic cutoffs are needed. (Source: Current Behavioral Neuroscience Reports)
