Association between auditory mismatch negativity and visual working memory in school-age children with attention deficit/hyperactivity disorder.

Background: Attention-deficit/hyperactivity disorder (ADHD) patients exhibit characteristics of impaired working memory (WM) and diminished sensory processing function. This study aimed to identify the neurophysiologic basis underlying the association between visual WM and auditory processing function in children with ADHD.

Methods: The participants included 86 children with ADHD (aged 6-15 years, mean age 9.

Study of the mechanism by which Bacillus subtilis improves the soil bacterial community environment in severely saline-alkali cotton fields.

Soil salinization severely damages the soil bacterial community environment. Bacillus subtilis can improve bacterial communities and enhance crop nutrient absorption. However, the mechanism by which B.

Sound localization and auditory selective attention in school-aged children with ADHD.

This study aimed to identify the neurophysiologic bases of auditory attention deficits in children with attention-deficit/hyperactivity disorder (ADHD), focusing on the electroencephalography component of auditory spatial selective attention [the N2 anterior contralateral component (N2ac)]. EEG data were collected from 7- to 11-year-old children with ADHD ( = 54) and age-, sex-, and IQ-matched typically developing (TD) children ( = 61), while they performed an auditory spatial selective task. For behavior, the children with ADHD showed a shorter reaction time (RT) but a higher RT coefficient of variability (RT) than TD children.

Lack of neural load modulation explains attention and working memory deficits in first-episode schizophrenia.

Objective: Although working memory (WM) deficits are well-recognized core features of schizophrenia, the underlying pathophysiological substrates of impairment in early psychosis before medication remain unclear. One possibility is that deficits in selective attention contribute to WM impairment.

Methods: EEG was acquired from 25 first-episode drug-naive schizophrenia patients and 26 matched controls while they performed a WM task.
