Special Issue Information

Dear Colleagues,

Neurodevelopmental trajectories across adolescence contribute to a heightened risk for substance use during this critical developmental period. Of particular relevance is the relative developmental timing and ‘imbalance’ of limbic and prefrontal circuits. Specifically, limbic circuits appear to mature earlier and may, by mediating “bottom-up” affective processes, drive risky behavior. Conversely, prefrontal cortical systems contributing to executive control processes and “top-down” behavioral regulation of risky and reward-seeking behaviors show a more protracted developmental course. In addition to these neural antecedents for substance use, the adolescent brain appears to be especially vulnerable to the consequences of drug and alcohol use.  Indeed, substance use in adolescence has been associated with detrimental alterations of brain structure, function, and connectivity.  While investigations of the neural precursors and consequences of adolescent substance use have largely focused on cross-sectional and retrospective studies, recent advances have included a number of prospective longitudinal investigations and those which include a true substance use naïve baseline sample.  Such approaches may be well placed to more fully elucidate and disentangle the neurodevelopmental correlates of the risk for and experience of substance use in adolescence.  These studies also have the potential to facilitate explorations of the relevance of the timing and escalation of substance use, both of which may be important in the magnitude of the impacts of adolescent substance use on brain development and the risk for later substance abuse and dependence.

This Special Issue will address these compelling issues—i.e., the neural antecedents and consequences of adolescent substance use, the relevance of timing and escalation of use, and later risk for substance use disorders—through a selection of papers representing methodological advances in the field, novel perspectives, and reviews of the extant literature.

Manuscripts that focus on the following cutting-edge research approaches are especially encouraged:

Brain-predicted age, machine learning/neural representations, multimodal, computational modeling, ecological momentary assessment, prospective studies of brain development and substance use, functional and structural connectome, precision functional mapping, graph theory metrics, leveraging big datasets (e.g., IMAGEN, ENIGMA, ABCD), dynamic/brain state and directed functional connectivity.

We are soliciting original research papers, brief reports, reviews & meta-analyses, and perspectives.

Background. Numerous neuropsychological studies have shown that cannabis use during adolescence and young adulthood led to deficits in sustained and selective attention. However, few studies have examined functional connectivity in attentional networks among young cannabis users, nor have characterized relationships with cannabis use patterns following abstinence. Methods. Differences in resting state functional connectivity (RSFC) within the dorsal (DAN) and ventral (VAN) attention networks were examined in 36 adolescent and young adult cannabis users and 39 non-substance using controls following two weeks of monitored abstinence. Observed connectivity differences were then correlated with past-year and lifetime cannabis use, length of abstinence, age of regular use onset, and Cannabis Use Disorder symptoms (CUD). Results. After controlling for alcohol and nicotine use, cannabis users had lower RSFC within the DAN network, specifically between right inferior parietal sulcus and right anterior insula, as well as white matter, relative to controls. This region was associated with more severe cannabis use measures, including increased lifetime cannabis use, shorter length of abstinence, and more severe CUD symptoms. Conclusions. Findings demonstrate that regular cannabis use by adolescents and young adults is associated with subtle differences in resting state connectivity within the DAN, even after two weeks of monitored abstinence. Notably, more severe cannabis use markers (greater lifetime use, CUD symptoms, and shorter abstinence) were linked with this reduced connectivity. Thus, findings support public policy aimed at reducing and delaying cannabis use and treatments to assist with sustained abstinence. Future longitudinal studies are needed to investigate causation.
