The neural mechanisms underlying susceptibility to eating more in response large portions (i.e., the portion size effect) remain unclear. Thus, present study examined how responses relate changes weight and energy consumed as increase. Associations were across brain regions traditionally implicated appetite control an appetitive network) well cerebellum, which has recently been appetite-related processes. Children without obesity BMI-for-age-and-sex percentile < 90; N = 63; 55% female)...
<h3>Background:</h3> The central nucleus of the amygdala and bed stria terminalis are involved primarily in phasic sustained aversive states. Although both structures have been implicated pathological anxiety, few studies with a clinical population specifically focused on them, partly because their small size. Previous work our group used high-resolution imaging to map resting-state functional connectivity healthy subjects at 7 T, confirming extending structural findings humans animals,...
Introduction Loss of control (LOC) eating is the perceived inability to how much eaten, regardless actual amount consumed. Childhood LOC-eating a risk factor for development binge-eating disorder (BED), but its neurobiological basis poorly understood. Studies in children with BED have shown both increased gray matter volume regions related top-down cognitive (e.g., dorsolateral prefrontal cortex) and reward-related decision making orbital frontal relative healthy controls. However, no...
Abstract Longer exclusive breastfeeding duration has been associated with differences in neural development, better satiety responsiveness, and decreased risk for childhood obesity. Given hippocampus sensitivity to diet potential role the integration of signals, may play a these relationships. We conducted secondary analysis 149, 7–11‐year‐olds (73 males) who participated one five studies that assessed responses food cues. Hippocampal grey matter volume was extracted from structural scans...
Previous research demonstrates that aversive stimuli can interrupt appetitive processing and brain regions involved with the of potential rewards, such as ventral striatum (VS), also respond to threatening information. Potential losses likewise activate VS and, thus, full extent which threat impact neural responses during incentive remains unclear. Here, unpredictable shock was used induce anxiety while participants performed monetary delay (MID) task functional magnetic resonance imaging...
The prevalence of obesity and eating disorders varies by sex, but the extent to which sex influences behaviors, especially in childhood, has received less attention. purpose this paper is review literature on differences behavior children present new findings supporting role child appetitive traits neural responses food cues. In children, shows basic taste response, acceptance, self-regulation, traits. New analyses demonstrate that interacts with weight status differentially influence...
Abstract While a large body of literature documents the impairing effect anxiety on cognition, performing demanding task was shown to be effective in reducing anxiety. Here we explored mechanisms this anxiolytic by examining how pharmacological challenge designed improve attentional processes influences interplay between neural networks engaged during and cognition. Using double-blind between-subject design, pharmacologically manipulated working memory (WM) using single oral dose 20 mg...
Decision-making contributes to what and how much we consume, deficits in decision-making have been associated with increased weight status children. Nevertheless, the relationships between cognitive affective processes underlying (i.e., processes) laboratory food intake are unclear. We used data from a four-session, within-subjects study investigate processes, intake, 70 children 7-to-11-years-old. was assessed Hungry Donkey Task (HDT), child-friendly task where make selections unknown...
The prefrontal cortex (PFC) is a key brain area in considering adaptive regulatory behaviors. This includes projections to regions of the limbic system such as amygdala, where nature functional connections may confer lower risk for anxiety disorders. PFC also associated with behaviors like executive functioning. Inhibitory control behavior encompassed by functioning, and generally viewed favorably socioemotional development. Yet, some research suggests that high levels inhibitory actually be...
