Objectives To date, most studies on autism spectrum disorder (ASD) have focused sample sets that were primarily or entirely composed of males; brain spontaneous activity changes in females remain unclear. The purpose this study was to explore the neural with ASD. Methods In study, resting-state functional magnetic resonance images (rs-fMRI) 41 ASD and typically developing (TD) controls obtained...

Abstract Background The visual system and its inherent functions undergo experience-dependent changes through the lifespan, enabling acquisition of new skills. Previous fMRI studies using tasks reported increased specialization in a number cortical regions subserving expertise. Although ample focused on representation long-term expertise brain, i.e. terms year, monthly-based early-stage remains...

Abstract Background Juvenile myoclonic epilepsy (JME) is the most common syndrome of idiopathic generalized epilepsy. Although resting-state functional magnetic resonance imaging (rs-fMRI) studies have found thalamocortical circuit dysfunction in patients with JME, pathophysiological mechanism JME remains unclear. In this study, we used three complementary parameters rs-fMRI to investigate aber...

BACKGROUND Using functional magnetic resonance imaging (fMRI), we determined brain regions that were activated/deactivated more by acupuncture at Taixi (KI3) than by non-acupoint or sham acupuncture. METHODS A total of 30 healthy volunteers were randomly divided into a KI3 group (15 subjects) and non-acupoint group (15 subjects). Subjects in KI3 group received a sham acupuncture and then a re...

It has been suggested by the first voxel-based morphometry investigation that betel quid dependence (BQD) individuals are presented with brain structural changes in previous reports, and there may be a neurobiological basis for BQD individuals related to an increased risk of executive dysfunction and disinhibition, subjected to the reward system, cognitive system, and emotion system. However, t...

background: the ventral tegmental area (vta) is well known for its role in cardiovascular control. it is demonstrated that about 20-30% of the vta neurons are gabaergic though their role in cardiovascular control is not yet understood. this study is carried out to find the effects of gaba a and gaba b receptors on cardiovascular response of the vta. methods: experiments were performed on uretha...

Conventional functional magnetic resonance imaging (fMRI) studies on motor feedback employ periodical blocked paradigm which does not allow frequency analysis of brain activity. Here, we carried out an fMRI study by using a continuous paradigm, that is, continuous (8 min) feedback of finger force. Borrowing an analytic method widely used in resting-state fMRI studies, that is, regional homogene...

BACKGROUND The dopamine transporter gene (DAT1) and visual memory deficits have been consistently reported to be associated with attention-deficit/hyperactivity disorder (ADHD). This study aimed to examine whether a DAT1 haplotype affected functional and structural brain alterations in children with ADHD and whether those alterations were associated with visual memory. METHOD We recruited a t...

Neuroplasticity is a common phenomenon in the human brain following nerve injury. It is defined as the brain's ability to reorganize by creating new neural pathways in order to adapt to change. Here, we use task-related and resting-state fMRI to investigate neuroplasticity in the primary sensory (S1) and motor cortex (M1) in patients with acute Bell's palsy (BP). We found that the period direct...
