NCT06888726
The goal of this clinical trial is to investigate whether Hi-tACS is effective and safe in treating negative symptoms of schizophrenia. Schizophrenic patients will receive treatment (Hi-tACS or shame stimulation) for 2 weeks. Negative symptoms, cognitive functioning, social functioning, and quality of life of intervention group and control group were assessed and compared between the two groups at baseline, 2 weeks, and 3 months post-intervention.
NCT06127056
To investigate the intervention effect of high-definition transcranial alternating current stimulation (HD-tACS) on patients with Non-suicidal Self-injury (NSSI) and its underlying neural mechanism by magnetic resonance imaging (MRI).
NCT06026826
To investigate the intervention effect of transcranial alternating current stimulation(tACS) on anxiety symptoms and somatic symptoms in patients with anxiety disorder and its underlying neural mechanism by MRI.
NCT05809076
In this study on healthy subjects, the effect of transcranial alternating current stimulation (tACS) will be investigated. In particular, the distinction between periodic and aperiodic electroencephalogram (EEG) activity will be considered, as well as the state-dependency phenomenon. Participants will take part in two experimental sessions that will include tACS stimulation (one real, one control). Before, during, and after stimulation, subjects will have their EEG recorded during rest or during tasks. The aim of this study is to investigate how the modulatory effects of gamma-tACS interact with intrinsic neural activity, measured in terms of periodic and aperiodic activity, as well as neurophysiological and behavioral modulation, taking into consideration the state-dependency phenomenon, which refers to the brain's activation state prior to stimulation.
NCT05312359
The investigators assume that tACS could improve amphetamine and alcohol dependent patients' executive-control function by adjusting the synchronization patterns and enhancing the functional connectivity of the prefrontal-ventral striatum pathway. A random controlled trial will be used to test the effect of θ-tACS treatment. Three months follow-up assessment will be conducted to test the changing of executive-control function and its mechanism.
NCT04560959
By analyzing the SEEG recordings, we explore the range of cortical functional responses to strings of 77.5Hz stimulations delivered by tACS,
