Early life stress is a potential precursor of eventual neuropsychiatric diseases and may result in altered neurodevelopment and function of the hippocampus, which thus provides a site at which potential interventions to modify the effects of early life stress may act. In this study, Sprague-Dawley rat pups comprising male and female animals underwent(More)
PURPOSE To investigate cerebral and cerebellar gray matter abnormalities in patients with first-episode major depressive disorder (MDD). MATERIALS AND METHODS We examined the structural difference in regional gray matter density (GMD) between 22 first-episode MDD patients and 30 age-, gender- and education-matched healthy controls by optimized voxel-based(More)
BACKGROUND The aim of this study was to investigate resting-state functional connectivity alteration of the right dorsolateral prefrontal cortex (DLPFC) in patients with first-episode major depressive disorder (MDD). METHODS Twenty-two first-episode MDD patients and thirty age-, gender- and education-matched healthy control subjects were enrolled. Rest(More)
BACKGROUND Obsessive-compulsive disorder (OCD) is a mental illness characterized by the loss of control. Because the cingulate cortex is believed to be important in executive functions, such as inhibition, we used functional magnetic resonance imaging (fMRI) techniques to examine whether and how activity and functional connectivity (FC) of the cingulate(More)
It is generally accepted that cognitive processes, such as learning and memory, are affected in depression. The present study used a rat model of depression, chronic unpredictable mild stress (CUMS), to determine whether hippocampal volume and neurochemical changes were involved in learning and memory alterations. A further aim was to determine whether(More)
We aim to clarify the mechanisms of acupuncture in treating mild cognitive impairment (MCI) and Alzheimer disease (AD) by using functional magnetic resonance imaging (fMRI). Thirty-six right-handed subjects (8 MCI patients, 14 AD patients, and 14 healthy elders) participated in this study. Clinical and neuropsychological examinations were performed on all(More)
This study constructs a rat brain T2 -weighted magnetic resonance imaging template including olfactory bulb and a compatible digital atlas. The atlas contains 624 carefully delineated brain structures based on the newest (2005) edition of rat brain atlas by Paxinos and Watson. An automated procedure, as an SPM toolbox, was introduced for spatially(More)
BACKGROUND In acupuncture brain imaging trials, there are many non-acupuncture factors confounding the neuronal mapping. The modality of the placebo, subjects' psychological attitude to acupuncture and their physical state are the three most confounding factors. OBJECTIVE To obtain more precise and accurate cerebral fMRI mapping of acupuncture. DESIGN(More)
UNLABELLED Attentional impairments are seen in many clinical syndromes, including attention deficit hyperactivity disorder, schizophrenia, and Alzheimer disease. Understanding the mechanism of attention can be helpful for the diagnosis and treatment of these diseases. The aim of this study was to assess brain glucose metabolic changes in a rat model of(More)
PURPOSE To automatically extract regions of interest (ROIs) and simultaneously preserve the anatomical characteristics of each individual, we developed a new atlas-based method utilizing a pair of coregistered brain template and digital atlas. MATERIALS AND METHODS Unlike the previous atlas-based method, this method treats each individual as the target(More)
