Transcranial Direct Current Stimulation for Impulsivity and Food-related Impulsivity in Obesity

In this study the investigators aim to assess whether transcranial direct current stimulation (tDCS; a safe non-invasive method for modulating the activity of specific brain regions) when applied over the orbitofrontal cortex (OFC) is able to modulate impulsivity in obese participants.

Effects of Brain Stimulation on Cognition Oscillations and GABA Levels in Schizophrenia

The purpose of this study is to use a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS), to test a set of hypotheses about the role of the prefrontal cortex in behavioral and neural correlates of cognition in schizophrenia.

Transcranial Direct Current Stimulation for Cognitive Improvement in Parkinson's Patients (tDCS) (tDCS)

The investigators hypothesize that multi-session anodal tDCS (atDCS) of the left dorsolateral prefrontal cortex (LDLPFC) will induce long-lasting effects in improving cognitive function and reducing cognitive fatigue and fatigability in PD patients.

Effects of Transcranial Direct Current Stimulation Associated With Cognitive Training in Alzheimer's Disease

Thus, the present study aims to investigate when (before, during or after) the tDCS should be applied to potentiate the effects of TCog in people with AD by comparing four protocols of application of neurostimulation associated with TCog.

Single Session of Anodal Cerebellar vs Cerebral Transcranial Direct Current Stimulation in Stroke Patients

To compare the effect of anodal cerebellar transcranial direct current stimulation (ctDCS) vs anodal cerebral direct current stimulation on balance, mobility and cognition in stroke patients in stroke patients

Optimization of NIBS for Treatment of Addiction

The purpose of this study is to assess the effects of transcranial Direct Current Stimulation (tDCS) applied in conjunction with Transcranial Ultrasound (TUS) for the treatment of addiction in opiate use disorder with chronic pain.
