The objectives of this study were to assess observers' preference for standard screens (SSs) or medical displays (MDs) in visualizing difficult-to-diagnose radiographic dental abnormalities and their preference for dental filter tools when utilized with MD systems.

A retrospective data set of 60 in vivo radiographs consisting of intraoral (n=20), panoramic (n=20), and cone beam computed tomography (n=20) images was created. Three image display monitors, including an SS, an MD, and an MD with 3 dental filter configurations (bone-low density enhancement filter, tooth-high density enhancement filter, and a combined filter representing regular MD), were utilized to assess 4 observers' monitor preferences in detecting radiographically subtle dental abnormalities. The data were analyzed by using binomial distribution. A P value ≤.05 was considered statistically significant.

Although observers expressed preference for MD for visualizing some abnormalities when examining intraoral and panoramic radiographs, MD was not preferred for detection of any abnormalities with cone beam computed tomography. There were no significant differences in preference for SS or MD overall (P ≥ .2024). Observers expressed significant preference for the filters in visualizing all but 2 abnormalities (P ≤ .0252).

The use of MD monitors enabled with dental filter tools may be preferred for visualizing certain subtle abnormalities.

There is emerging evidence for abnormal beta oscillations in psychosis. Beta oscillations are likely to play a key role in the coordination of sensorimotor information that is crucial to healthy mental function. Growing evidence suggests that beta oscillations typically manifest as transient beta bursts that increase in probability following a motor response, observable as post-movement beta rebound. Evidence indicates that post-movement beta rebound is attenuated in psychosis, with greater attenuation associated with greater symptom severity and impairment. Delineating the functional role of beta bursts therefore may be key to understanding the mechanisms underlying persistent psychotic illness.

We used concurrent electroencephalography and functional magnetic resonance imaging to identify blood oxygen level-dependent correlates of beta bursts during the n-back working memory task and intervening rest periods in healthy participants (n= 30) and patients with psychosis (n= 48).

During both task blocks avate latently maintained sensorimotor information and are dysregulated and inefficient in psychosis. We propose that abnormalities in the mechanisms by which beta bursts coordinate reactivation of contextually appropriate content can manifest as disorganization, working memory deficits, and inaccurate forward models and may underlie a core deficit associated with persisting symptoms and impairment.
Childhood obsessive-compulsive symptoms (OCSs) are common and can be an early risk marker for obsessive-compulsive disorder. The Adolescent Brain and Cognitive Development (ABCD) Study provides a unique opportunity to characterize OCSs in a large normative sample of school-age children and to explore corticostriatal and task-control circuits implicated in pediatric obsessive-compulsive disorder.

The ABCD Study acquired data from 9- and 10-year-olds (N= 11,876). Linear mixed-effects models probed associations between OCSs (Child Behavior Checklist) and cognition (NIH Toolbox), brain structure (subcortical volume, cortical thickness), white matter (diffusion tensor imaging), and resting-state functional connectivity.

OCS scores showed good psychometric properties and high prevalence, and they were related to familial/parental factors, including family conflict. Higher OCS scores related to better cognitive performance (β= .06, t

= 6.28, p < .001, η

= .01), particularly verbal, when controlling fo connectivity, for identifying children at increased risk for obsessive-compulsive disorder.
OCSs are common and may persist throughout childhood. find more Corticostriatal connectivity and attention network connectivity are likely mechanisms in the subclinical-to-clinical spectrum of OCSs. Understanding correlates and mechanisms of OCSs may elucidate their role in childhood psychiatric risk and suggest potential utility of neuroimaging, e.g., dorsal attention-default mode connectivity, for identifying children at increased risk for obsessive-compulsive disorder.
It is well established that exposure to adversity, especially during sensitive periods of development such as childhood, has both behavioral (e.g., increasing one's risk for psychiatric illnesses) and neurobiological consequences. But could these effects of early-life exposure to adversity also be transmitted across generations? We directly address this question, investigating the associations between maternal exposure to adversity during her own childhood and neural connectivity in her neonate.

Mothers from a sample of Black mother-neonate dyads (n= 48)-a group that is disproportionately affected by early-life adversity-completed questionnaires assessing their current distress (i.e., a composite measure of anxiety, depression, and perceived stress) during the first and third trimesters of pregnancy and retrospectively reported on their own childhood experiences of abuse and neglect. At 1 month postpartum, neonatal offspring of these women underwent a resting-state functional magnetic resonance imaging scan during natural sleep.

Greater maternal exposure to emotional neglect during her own childhood correlated with stronger functional connectivity of two different frontoamygdala circuits in these neonates, as early as 1 month after birth. This effect was specific to early experiences of emotional neglect and was not explained by maternal exposure to other forms of childhood maltreatment or by maternal distress during pregnancy.

These results provide novel evidence that the absence of emotional support early in a mother's life, years before conception, are associated with neural changes-namely, in functional connectivity between the amygdala and medial prefrontal regions-in her offspring shortly after birth.
