Summary: Prenatal exposure to environmental tobacco smoke may have detrimental effects on children's brain structure and function, affecting cognitive control and attention. The study results show that children exposed to ETS had smaller thalamic and inferior frontal gyrus volumes, and exhibited increased brain activation during cognitive conflict resolution.

Summary: This study demonstrates that generalization can occur in response to stress and result from reactivation of specific context representations. Abnormal cholinergic signaling may underlie maladaptive cognitive and behavioral generalization linked to negative affective states. These findings provide insights into the mechanisms of maladaptive generalization.

Summary: In movement disorders such as Parkinson's disease, disruptions in cholinergic signaling and aberrant activity in striatal cholinergic interneurons may contribute to gait imbalance. The integration of cortical and striatal mechanisms guided by cholinergic activity plays a critical role in complex movement control in parkinsonian fallers and older individuals with gait disorders.

Summary: Mental health symptoms resulting from trauma exposure and substance use disorders often co-occur, with a potential shared etiology being an important question in translational neuroscience. Despite advancements in genetics, basic science, and neuroimaging improving understanding, the high rates of comorbidity and relapse remain a clinical challenge.

Summary: Cholinergic interneurons play crucial roles in striatal circuits and functions. The activation of acetylcholine signal via muscarinic receptors is well studied, but recent data suggest that nicotinic receptors located on GABAergic interneurons are equally important. Stimulation of cholinergic interneurons activates these receptors and leads to inhibitory effects on striatal projection neurons.

Summary: This study found that neonatal overfeeding disrupts the mesolimbic dopaminergic circuitry and causes changes in feeding behavior. Additionally, alterations observed during the neonatal period persist into adulthood and impact sensory-specific satiety.

Summary: This study investigated the role of basal forebrain (BF) inputs in modulating activity of different subtypes of periglomerular (PG) interneurons in the olfactory bulb (OB). The results showed that GABAergic BF inputs effectively inhibited PG cell firing, while cholinergic inputs excited a previously overlooked PG cell subtype. These findings highlight the importance of external inputs in synaptic inhibition in the OB.

Summary: Sexual transition in male Drosophila is controlled by hormonal changes, which inhibit the activity of courtship-motivating circuit elements rather than constructing new neural circuits. Hormonal changes gate the transition to sexuality by permitting activity in latent motivational circuit elements in otherwise asexual males, similar to mammalian adolescence.

Summary: Dopamine plays a positive role in cognitive control, affecting both cognitive control capacity and cognitive motivation. Striatal dopamine may enhance control by increasing sensitivity to the costs and benefits of cognitive effort, shaping competition between controlled and prepotent actions. Differing cost-benefit tradeoffs mediated by dopamine signaling in distinct cortico-striatal subregions may reconcile conflicting findings on the impact of dopamine on cognitive control.

Summary: Choline acetyltransferase (ChAT) plays a critical role in the pathogenicity of experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis (MS). ChAT-deficient Th17 cells in mice resist disease progression and show reduced brain-infiltrating immune cells. ChAT expression in Th17 cells is associated with TCR signaling, Bhlhe40 transcription factor, and increased mRNA levels of Il2, Il17, Il22, and Il23r.

Summary: The basal forebrain cholinergic system (BFCS) has been associated with age-related cognitive changes and Alzheimer's disease (AD). Despite limitations in cholinergic interventions, there is a renewed interest in studying the BFCS using novel frameworks. This article outlines the structure and function of the BFCS, its role in cognition and emotion, and its vulnerability to aging and AD. It also explores the BFCS in relation to the amyloid hypothesis, selective vulnerability, pathology spread, and sleep health in AD research.

Summary: Despite increased prevalence of maternal cannabis use, little is understood regarding potential long-term effects of prenatal cannabis exposure (PCE) on neurodevelopmental outcomes. This study found that PCE induces behavioral, neuronal, and molecular alterations in the mesolimbic system in male and female offspring, resembling neuropsychiatric endophenotypes. Moreover, PCE resulted in profound dysregulation of critical fatty acid pathways in the developing brain lipidome.

Summary: About one-third of college students drop out before finishing their degree, and the majority take longer than 4 years to complete their education. A study developed machine learning algorithms to predict if and when first-time college undergraduates will graduate based on their records. With an accuracy of 79%, the algorithms can identify students who may benefit from additional support, including those with high financial need but adequate degree progress.

Summary: Effective mentor training is crucial for early-career researchers, and particularly beneficial for those who are new to mentoring. Mentors with more experience with diverse mentees tend to rate their mentoring skills higher, and women tend to rate themselves higher in addressing diversity within the mentoring relationship.
