Background: White noise stimulation has demonstrated efficacy in enhancing working memory in children with ADHD. However, its impact on other executive functions commonly affected by ADHD, such as inhibitory control, remains largely unexplored. This research aims to explore the effects of two types of white noise stimulation on oculomotor inhibitory control in children with ADHD.
Method: Memory guided saccade (MGS) and prolonged fixation (PF) performance was compared between children with ADHD ( = 52) and typically developing controls (TDC, = 45), during auditory and visual white noise stimulation as well as in a no noise condition.
Results: Neither the auditory nor the visual white noise had any beneficial effects on performance for either group.
Conclusions: White noise stimulation does not appear to be beneficial for children with ADHD in tasks that target oculomotor inhibitory control. Potential explanations for this lack of noise benefit will be discussed.

Zoo animals are regularly exposed to a plethora of sensorial stimuli beyond their control, which can adversely impact their behaviour and welfare, including unfamiliar faces, excessive noise and intrusive visitor interaction. Zoos have implemented various measures, such as enrichments and regulation of visitor behaviour, to mitigate these effects. However, guided tours have not been used to simultaneously control visitor behaviour and maintain animal welfare.

Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.
Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.

The dataset presented contains the experimental structural response, in the frequency domain, of a suspended steel plate to a point force excitation. The plate is excited by a mechanical point force generated by a Brüel & kJær shaker with a white noise signal input from 3.125 Hz to 2000 Hz.

Due to PET's low spatial resolution, image noise, and spill-over of signal from adjacent white-matter into gray-matter, there are inconsistencies in ratings among trained readers. A set of 264 F-Florbetaben (amyloid) PET/MRI exams were reconstructed using conventional ordered subset expectation maximization (OSEM) method and MR-guided block sequential regularized expectation maximization (MRgBSREM) method.

The research explores the relationship between auditory cues and static postural stability in individuals with hearing impairment.
Methods: 34 young adult cochlear implant users, consisting of 15 males and 19 females aged 18-35 years, underwent various balance tests, including the modified Clinical Tests of Sensory Interaction on Balance (mCTSIB) and the Unilateral Stance Test (UST), under different auditory conditions: (1) White noise stimulus present with the sound processor activated, (2) Ambient noise present with the sound processor activated, and (3) Sound processor deactivated.
