We hypothesized that compared to healthy controls, long-term abstinent substance dependent individuals (SDI) will differ in their effective connectivity between large-scale brain networks and demonstrate increased directional information from executi

Introduction The P50, a positive auditory-evoked potential occurring 50 msec after an auditory click, has been characterized extensively with electroencephalography (EEG) to detect aberrant auditory electrophysiology in disorders like schizophrenia (

Compared with healthy individuals, patients with schizophrenia had greater resting state hippocampal activity that was inversely related to schizophrenia symptoms and cognitive deficits, indicating a possible brain biomarker for developing cognitive

Objective: To study the phase stability of the 40 Hz auditory steady-state response (ASSR) in Sz, and in addition, to investigate inter-hemispheric phase synchronization using ipsilateral and contralateral hemisphere gamma band ASSRs. Methods: Whole

Reductions in gamma band phase synchrony and evoked power have been reported in schizophrenic subjects in response to auditory stimuli. These results have been observed in the EEG at one or two electrode sites. We wished to extend these results using

Gamma band activity has been implicated in cortical information processing. Separate studies have found deficits in MEG/EEG gamma power from various sensory modalities in various mental disorders, most notably in psychoses such as schizophrenia. In t

A novel magnetoencephalography (MEG) system was designed at Los Alamos National Laboratory (LANL) that incorporates a helmet-shaped superconductor in order to increase the signal to noise ratio. The magnetic field perturbations caused by the supercon

To better understand the cortical circuitry underlying connectivity between large-scale neural networks, we develop a novel, data-driven approach to identify potential integration subregions. Between-network connectivity (BNC) associated with any ana
