In this paper, motivated by the fading effect in wireless communications, where severe channel fading is related to information loss during the transmission, we evaluate and analyze the fading effect in time-varying functional connectivity of AD, MCI and NC subjects based on the resting-state fMRI data, and then apply that for AD, MCI, NC classification. We show that in some critical brain regions, compared with NC subjects, AD subjects suffer more severe and long lasting fading in the functional connectivity level [...]

Mechanisms leading to neuronal cell death in human pathology are far from being fully delineated. Understanding the molecules involved in neuronal death and the timing of their recruitment might help to explain the natural history of degenerative processes, including the morphological abnormalities observed in Alzheimer’s disease (AD). Moreover, it might help refine the diagnosis by defining new molecular markers as well as find effective therapies, especially for slow cognitive deficits, often associated wit [...]

Temporomandibular disorders (TMD) are a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joint (TMJ), the masticatory muscles, and branches of the trigeminal nerve. TMD is the most common chronic oral facial pain disorder. Pain associated with TMD can be clinically expressed as myogenous or arthrogenous in etiology. The myogenous variant of TMD is characterized by pain in the muscles of mastication. The arthrogenous form of TMD is caused by pain in the joint leading to synovi [...]

Alzheimer’s disease (AD) causes severe cognitive dysfunction and has long been studied for the underlining physiological and pathological mechanisms. Several biomedical imaging modalities have been applied, including MRI, PET, and high-resolution optical microscopy, for research purposes. However, there is still a strong need for imaging tools that can provide high spatiotemporal resolutions with relatively deep penetration to enhance our understanding of AD pathology and monitor treatment progress in fundamental r [...]

Anorexia nervosa is a psychiatric disorder, the etiopathogenesis of which is still not fully understood. Currently, the most accredited model is a multifactorial model, which involves interaction between predisposing factors of biological nature, partly genetically determined, and psychological/personological and environmental socio-cultural factors. The last 20 years have led to the advancement in our knowledge on the mechanisms of energy homeostasis maintenance. There has been a veritable explosion of studies aim [...]

Case studies have associated catatonia with withdrawal from benzodiazepines and clozapine, both of which have been shown to increase GABA activity. Long-term use of GABAergic medications could result in GABAA downregulation and sudden discontinuation of the GABAergic drug could lead to a GABA hypoactive state which could predispose the patient to catatonia. The anticonvulsant topiramate, is known to increase brain GABA activity. Prader-Willi syndrome (PWS) is a genetic imprinting disorder characterized by lack of e [...]

Driven exercise (i.e., the tendency to exercise in excess to influence weight/shape or regulate emotion) is difficult to manage in the context of anorexia nervosa, and is associated with poorer treatment outcomes, and psychological and medical severity. Driven exercise is observed in a considerable number of those diagnosed with anorexia nervosa; however, to date, this hallmark symptom remains poorly understood. Dopamine signaling is implicated in motivating and maintaining appetitive behavior among patients with e [...]

Self-reports and actigraphy are common methods of sleep monitoring. Portable polysomnography (p-PSG) may serve as a screening tool in natural environments. Common concerns with its use are that sleep and compliance might be affected. Further, dysfunctional beliefs of the subjects may contribute to sleep disturbances, which might manifest throughout sleep monitoring. This study examined the effect of monitoring sleep patterns and attitudes among healthy individuals. Sixty-eight physically active university students [...]

With an increasing prevalence of children with Autism Spectrum Disorder (ASD) in schools, teachers are in need of different effective ways to educate these individuals who have distinctly different needs and modalities of experience. One area that has been explored is neuroeducation, or using findings from neuroscientific research to inform classroom practice. Neuroscientific findings appear to center on two main themes of neurological differences among children with ASD: sensory processing and emotional processing [...]

We investigated whether healthy older adults who live in female-dominated old age care homes can identify the gender of male and female faces of people from different ethnicities in the same way as young adults. We hypothesized that this mainly female environment would lead by exposure to a female-gender bias. A sample of 40 participants aged 20-30 and 70-80 years identified the sex-of-face of 120 images of young and old adults, male and female faces, black and white faces, presented in a randomized sequence in a s [...]
