Resting State Functional ConnectivityPrimary· 24 minutes
The main outcomes of this study are brain imaging related. Using a neuroimaging technique called resting state functional connectivity, which is a statistical dependence between time series of electro-physiological activity and (de)oxygenated blood levels in distinct regions of the brain. Modularity is measured on a -1 to 1 scale, with higher scores indicating stronger community structure, or a stronger tendency of clusters of brain regions to separate into distinct, highly interconnected networks with sparse connections across networks. The optimal modularity value depends on the context. For

Sponsor's own description
Aim: Evaluate whether sonicating the Nucleus Accumbens (NAc) with transcranial focused ultrasound modifies functional connectivity between the NAc and the prefrontal cortex (PFC).
In this single visit, open-label pilot trial, we plan to evaluate whether transcranial focused ultrasound (tFUS), delivered to the nucleus accumbens (NAc) within the magnetic resonance imaging (MRI) scanner will impact resting state functional connectivity between the NAc and functionally connected brain regions like the prefrontal cortex (PFC) and the anterior cingulate cortex (ACC) in up to 10 healthy individuals.
HYPOTHESIS : tFUS will reduce prefrontal cortex (PFC)-NAc functional connectivity, in healthy individuals. We will investigate this hypothesis by administering tFUS within to MRI scanner to healthy individuals and conduct resting state functional neuroimaging before- and after the tFUS stimulation.
