Significance Hippocampal hyperactivity predicts psychosis and may disrupt aspects of cognition in schizophrenia. Here, we use interneuron precursor transplants mice lacking cyclin D2 ( Ccnd2 ) to test links between hippocampal GABAergic interneurons psychosis-relevant phenotypes. -null show parvalbumin deficits increased vivo excitatory neuron spiking metabolic activity. This disinhibition is associated with cognitive excess dopamine Transplanting progenitors derived from the embryonic...

Decades of research document an association between neurocognitive dysfunction and externalizing behaviors, including rule-breaking, aggression, impulsivity. However, there has been very little work that examines how multiple functions co-occur within individuals which combinations are most relevant for behaviors. Moreover, Latent Profile Analysis (LPA), a widely used method grouping in person-centered analysis, often struggles to balance the tradeoff good model fit (splitting participants...

Exposure therapy — exposure to a feared stimulus without harmful consequences can reduce fear responses in many mental disorders. However, such relief is often partial and temporary: return after the has ended. Conditioning research identified three mechanisms for of fear, viz. change physical context (renewal), passage time (spontaneous recovery), an encounter with fear-producing unconditioned (reinstatement). To understand why returns thereby develop more effective therapies, we...

Abstract Objective Environmental factors have long been shown to influence brain structure and adolescent psychopathology. However, almost no research has included environmental spanning micro-to-macro-systems, structure, psychopathology in an integrated framework. Here, we assessed the ways degree which multi-system during late childhood predict subcortical volume early adolescence. Method We used baseline 2-year follow-up data from Adolescent Brain Cognitive Development SM Study ( N =...
