Gamma frequency-range abnormalities to auditory stimulation in schizophrenia.
BACKGROUND Basic science studies at the neuronal systems level have indicated that gamma-range (30-50 Hz) neural synchronization may be a key mechanism of information processing in neural networks,Expand

Clinical and empirical applications of the Rey–Osterrieth Complex Figure Test
The Rey–Osterrieth Complex Figure Test (ROCF), which was developed by Rey in 1941 and standardized by Osterrieth in 1944, is a widely used neuropsychological test for the evaluation of visuospatialExpand

Subgenual cingulate cortex volume in first-episode psychosis.
OBJECTIVE Gray matter volume and glucose utilization have been reported to be reduced in the left subgenual cingulate of subjects with familial bipolar or unipolar depression. It is unclear whetherExpand

The effect of meditation on brain structure: cortical thickness mapping and diffusion tensor imaging.
A convergent line of neuroscientific evidence suggests that meditation alters the functional and structural plasticity of distributed neural processes underlying attention and emotion. The purpose ofExpand

Increased default mode network connectivity associated with meditation
Areas associated with the default mode network (DMN) are substantially similar to those associated with meditation practice. However, no studies on DMN connectivity during resting states have beenExpand

Fractal dimension in human cortical surface: Multiple regression analysis with cortical thickness, sulcal depth, and folding area
Fractal dimension (FD) has been widely used to provide a quantitative description of structural complexity in the cerebral cortex. FD is an extremely compact measure of shape complexity, condensingExpand
