Background: Behavioral economic theory suggests that the value of alcohol depends upon elements of the choice context, such that increasing constraints on alternatives (e.g., price) or increasing the benefits of alcohol (e.g., social context) may result in greater likelihood of heavy drinking. The P3 event-related potential elicited by alcohol-related cues, a proposed marker of incentive salience, may be an electrophysiological parallel for behavioral economic alcohol demand. However, these indices have not been connected in prior research, and studies typically do not disaggregate social influences in the context of alcohol cue reactivity.
Method: The current study recruited heavy drinking young adults (N = 81) who completed measures of alcohol use and alcohol demand, in addition to a 2 (social/nonsocial) × 2 (alcohol/nonalcohol) visual oddball task to elicit the P3.
Results: In multilevel models controlling for demographic characteristics, P3 reactivity was greater to alcohol (p < 0.001) and social (p < 0.001) cues than to nonalcohol and nonsocial cues, but without a significant interaction. Higher alcohol consumption (p = 0.02) and lower elasticity of demand (p = 0.01) were associated with greater P3 response to alcohol than nonalcohol cues.
Conclusions: The results highlight a brain-behavior connection that may be an important marker for alcohol reward across units of analysis and may be sensitive to changes in the economic choice contexts that influence the likelihood of alcohol use.

Historically, electrophysiological correlates of scene processing have been studied with experiments using static stimuli presented for discrete timescales where participants maintain a fixed eye position. Gaps remain in generalizing these findings to real-world conditions where eye movements are made to select new visual information and where the environment remains stable but changes with our position and orientation in space, driving dynamic visual stimulation. Co-recording of eye movements and electroencephalography (EEG) is an approach to leverage fixations as time-locking events in the EEG recording under free-viewing conditions to create fixation-related potentials (FRPs), providing a neural snapshot in which to study visual processing under naturalistic conditions.

We present the case of a toddler displaying neuroregression post-acute gastroenteritis, initially suggesting neurodegenerative disorders. Further investigations showed atypical results-neuroimaging was inconsistent with suspected disorders, while fundus evaluation, evoked potentials and nerve conduction velocity were normal. Specialised tests using gas chromatography mass spectrometry and tandem mass spectrometry identified methylmalonic acidaemia (MMA), implicating abnormal neurometabolism.

Audiovisual associative memory and audiovisual integration involve common behavioral processing components and significantly overlap in their neural mechanisms. This suggests that training on audiovisual associative memory may have the potential to improve audiovisual integration. The current study tested this hypothesis by applying a 2 (group: audiovisual training group, unimodal control group) * 2 (time: pretest, posttest) design.

Objective: The study aimed to explore the vestibular function in children with neurodevelopmental disorders (NDDs).
Methods: Twenty-eight participants with a NDD (6 girls, 22 boys; 6-13 years; 9;3 ± 2;4 years) were enrolled in this pilot study. Sixteen participants had a single NDD (Autism Spectrum Disorder: n = 7, Developmental Coordination Disorder: n = 3; Attention Deficit/Hyperactivity Disorder: n = 6), the remaining 12 had comorbid NDDs.

Fear avoidance (FA) describes beliefs and behaviors related to avoiding movements or activities after a painful event. FA is a prevalent issue that limits the recovery outcomes and social reintegration of burn survivors. However, as current literature focuses on chronic conditions, understanding the impact and treatment of FA within sudden onset musculoskeletal (MSK) conditions, specifically in the burn survivor population, is lacking.
