BACKGROUND Recent resting-state fMRI studies on major depressive disorder (MDD) have found altered temporal correlation between low-frequency oscillations (LFOs). However, changes on the amplitudes of these LFOs remain largely unknown. METHODS Twenty-two medication-naive, first-episode patients with MDD and 19 age-, sex-, education-matched healthy(More)
BACKGROUND The previous resting perfusion or task-based studies have provided evidence of functional changes in the brains of patients with late-life depression (LLD). Little is known, so far, about the changes in the spontaneous brain activity in LLD during the resting state. The aim of this study was to investigate the spontaneous neural activity in(More)
Functional neuroimaging studies have found intra-regional activity and inter-regional connectivity alterations in patients with post-traumatic stress disorder (PTSD). However, the results of these studies are based on group-level statistics and therefore it is unclear whether PTSD can be discriminated at single-subject level, for instance using the machine(More)
This study aims to investigate the neurostructural foundations of the human personality in young adults. High-resolution structural T1-weighted MR images of 71 healthy young individuals were processed using voxel-based morphometric (VBM) approach. Multiple regression analyses were performed to identify the associations between personality traits and gray(More)
Scalp electrophysiological studies have supposed that emotional intensity is processed from about 170 ms. However, this is inconsistent with the rapid emotion detection of the amygdala at around 100 ms. Besides, it is unreasonable to apply this assertion to all emotional types considering emotional-specific neural networks and fast/slow emotional routes.(More)
Recent research has shown that social anxiety disorder (SAD) is accompanied by abnormalities in brain functional connections. However, these findings are based on group comparisons, and, therefore, little is known about whether functional connections could be used in the diagnosis of an individual patient with SAD. Here, we explored the potential of the(More)
BACKGROUND Neuroimaging studies suggest that treatment-naive depression (TD) is characterized by abnormal functional connectivity between specific brain regions. However, the question surrounding the structural basis of functional aberrations in TD patients still remains. METHODS In the present study, diffusion tensor imaging tractography was employed to(More)
OBJECTIVE The network hubs, characterized by the large number of connections to other regions, play important roles in the proper and effective transfer of information. Previous functional neuroimaging studies have demonstrated that patients with social anxiety disorder (SAD) have aberrant functional connectivity. The changing pattern in functional network(More)
For dealing with the complexity in gaining inverse kinematics solution of 7-DOF manipulator, a new approach based on RBF neural network is proposed. To solve the problem of multi-solution caused by redundancy, a rule for a joint of "best compliance" based on weighted least square method is supposed at the beginning of this paper, which makes the(More)
For dealing with the complexity in gaining solution for inverse kinematics of 7-DOF manipulator, a new approach based on GA (genetic algorithm) is proposed. To solve the problem of multi-solution caused by redundancy, a rule for a joint of "best compliance" based on weighted least square method is supposed at the beginning of this paper, which makes the(More)
