The effect of non-invasive transcranial focused ultrasound for depression on the default mode network: an open-label pilot trial [PDF]

Frontiers in Psychiatry
BackgroundMajor depressive disorder (MDD) affects one in five individuals, often recurs, and up to 50% of cases are deemed treatment resistant. Aberrant brain connectivity is associated with both depression symptoms and a thought pattern characteristic ...

Deep cerebellar tFUS engages cortical circuits via convergent local and sensory-driven mechanisms

bioRxiv
Abstract Transcranial focused ultrasound (tFUS) enables non-invasive access to deep brain structures with high spatial precision, but its mechanisms of action remain elusive and under active investigation. The leading hypothesis posits that tFUS exerts its neuromodulatory effects through direct activation of neurons, while others ...
