Objective Children who are less fit reportedly have lower performance on tests of cognitive control and differences in brain function. This study examined the effect an exercise intervention function during two tasks overweight children. Design Methods Participants included 43 unfit, (BMI ≥ 85th percentile) children 8‐ to 11‐years old (91% Black), were randomly divided into either aerobic ( n = 24) or attention group 19). Each was offered a separate instructor‐led after‐school program every...
Abstract In childhood, excess adiposity and low fitness are linked to poor academic performance, lower cognitive function, differences in brain structure. Identifying ways mitigate obesity‐related alterations is of current clinical importance. This study examined the effects an 8‐month exercise intervention on uncinate fasciculus, a white matter fiber tract connecting frontal temporal lobes. Participants consisted 18 unfit, overweight 8‐ 11‐year‐old children (94% Black) who were randomly...
Aerobic fitness is associated with white matter integrity (WMI) in adults as measured by diffusion tensor imaging (DTI). This study examined the effect of an 8-month exercise intervention on WMI children. Participants were 18 sedentary, overweight (BMI ≥85th percentile) 8- to 11-year-old children (94% Black), randomly assigned either aerobic (n = 10) or sedentary attention control group 8). Each was offered instructor-led after-school program every school day for approximately 8 months....
There is growing awareness that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, even in its mild or moderate forms, can include long-term neuropsychological deficits. Standardized neuropsychological, psychiatric, neurological, and olfactory tests were administered to 45 patients 236.51 ± 22.54 days after hospital discharge following severe, moderate, severity from SARS-CoV-2 infection (severe = intensive care unit hospitalization, conventional no hospitalization)....
Emotional expressions offer important social cues about the expresser’s intentions and risks or rewards in environment. The current study investigated how individual differences interpretation of ambiguous facial (valence bias) are impacted by intergroup racial biases. In an online 409 racially diverse US participants, we found that across groups, participants judged in-group faces more positively than out-group regardless expression (happy, angry, surprised). Furthermore, valence bias...
Heightened reactivity to ambiguous emotional stimuli, such as surprized faces, is a transdiagnostic psychopathology risk factor. Women show elevated amygdala activation stimuli relative men, which may underlie their significantly higher for mood disorders. Moreover, there are sex/gender differences in the effects of stress on both emotion processing and regulation, with greater impact negative emotionality females. We predicted that chronic would be associated stronger these amplified...
Abstract Until recently, brain networks underlying emotional voice prosody decoding and processing were focused on modulations in primary secondary auditory, ventral frontal prefrontal cortices, the amygdala. Growing interest for a specific role of basal ganglia cerebellum was recently brought into spotlight. In present study, we aimed at characterizing such subcortical regions vocal emotion processing, level both activation functional effective connectivity, using high resolution magnetic...
Risk factors for long-term non-motor symptoms and quality of life following subthalamic nucleus deep brain stimulation (STN DBS) have not yet been fully identified. In the present study, we investigated impact motor symptom asymmetry in Parkinson's disease. Data were extracted 52 patients with disease (half predominantly left-sided half right-sided ones) who underwent bilateral STN a matched healthy control group. Performances cognitive tests, apathy depression symptoms, as well...
During childhood, verbal learning and memory are important for academic performance. Recent functional MRI studies have reported on the correlates of proficiency, but few underlying structural correlates. The present study sought to test relationship between fronto-temporal white matter integrity proficiency in children. Diffusion weighted images were collected from 17 Black children (age 8-11 years) who also completed California Verbal Learning Test. To index integrity, fractional...
Cognitive control supports flexible behavior adapted to meet current goals and can be modeled through investigation of saccade tasks with varying cognitive demands. Basic prosaccades (rapid glances toward a newly appearing stimulus) are supported by neural circuitry, including occipital posterior parietal cortex, frontal supplementary eye fields, basal ganglia. These trials contrasted complex antisaccades (glances the mirror image location stimulus), which characterized greater functional...
The subthalamic nucleus (STN) is involved in different aspects of emotional processes and more specifically prosody recognition. Recent studies on the behavioral effects deep brain stimulation (DBS) patients with Parkinson's disease (PD) have uncovered an asymmetry vocal emotion decoding PD, left-onset PD showing deficits for processing happy voices. Whether how affects STN electrophysiological responses to prosody, however, remains unknown. In current study, local field potential activity...

Mutations affecting the PAX6 gene result in aniridia, a condition characterized by lack of an iris and other panocular defects. Among humans with structural abnormalities also have been reported within brain. The current study examined functional implications these deficits through "resting state" or task-free magnetic resonance imaging 12 individuals aniridia healthy age- gender-matched controls. Using independent components analysis dual regression, individual patterns connectivity...
