Modulation of somatosensory evoked fields from SI and SII by acute GABAA-agonism and paired-pulse stimulation
The purpose of the present study was to shed light on the physiology underlying somatosensory evoked magnetic fields (SEFs) by means of pharmacological manipulation with the GABA A agonist lorazepamExpand

MRI-constrained spectral imaging of benzodiazepine modulation of spontaneous neuromagnetic activity in human cortex
Spontaneous electromagnetic brain rhythms have been widely used in human neuropharmacology, but their applicability is complicated by the difficulties to localize their origins in the human cortex.Expand

Cognitive function during early abstinence from opioid dependence: a comparison to age, gender, and verbal intelligence matched controls
BackgroundIndividuals with opioid dependence have cognitive deficits during abuse period in attention, working memory, episodic memory, and executive function. After protracted abstinence consistentExpand

The interplay of lorazepam-induced brain oscillations: microstructural electromagnetic study
OBJECTIVE The effects on cortical rhythms of a single-dose (30 microg/kg) administration of the GABAA agonist lorazepam were examined in a randomized, double-blind, cross-over, placebo-controlledExpand

Opioid withdrawal results in an increased local and remote functional connectivity at EEG alpha and beta frequency bands
Withdrawal may be a natural model to study craving and compulsive drug seeking, since craving can be viewed as a conditioned dysphoric state. It has been suggested that functional connectivityExpand

Reorganization of the composition of brain oscillations and their temporal characteristics in opioid dependent patients
In the present study, we examined the composition of electroencephalographic (EEG) brain oscillations in broad frequency band (0.5-30 Hz) in 22 opioid-dependent patients and 14 healthy subjectsExpand

Impaired pre-attentive auditory processing in opioid dependence with and without benzodiazepine co-dependence revealed by combined magnetoencephalography and electroencephalography
Cognitive dysfunctions may be a significant factor in drug-seeking behavior, reducing the efficiency of rehabilitation in opioid dependence. Neurophysiological basis of these dysfunctions is poorlyExpand

Local and remote functional connectivity of neocortex under the inhibition influence
The current paper focuses on a relatively new and promising area of the study of EEG transformations during brain information processing based on the reduction of the signal to the discreteExpand

Enhancement of GABA‐related signalling is associated with increase of functional connectivity in human cortex
Structural or operational synchrony analysis with EEG was conducted in order to detect functional interaction between cortical areas during an enhanced inhibition induced by the GABAergic agonistExpand

Increased local and decreased remote functional connectivity at EEG alpha and beta frequency bands in opioid-dependent patients
RationaleAlthough researchers now have a working knowledge of key brain structures involved in realization of actions of substance abuse and addiction, deeper understanding will require examinationExpand
