BackgroundNon-invasive brain stimulation techniques such as transcranial magnetic and direct current hold promise for inducing plasticity. However, their limited precision may hamper certain applications. In contrast, Transcranial Ultrasound Stimulation (TUS), known its deep targeting capabilities, requires further investigation to establish efficacy in producing enduring effects treating neurological psychiatric disorders.ObjectiveTo investigate the of different pulse repetition frequencies...
Abstract Objective. Transcranial ultrasound stimulation (TUS) presents challenges in wave transmission through the skull, affecting study outcomes due to aberration and attenuation. While planning strategies incorporating 3D computed tomography (CT) scans help mitigate these issues, they expose participants radiation, which can raise ethical concerns. A solution involves generating skull masks from participants’ anatomical magnetic resonance imaging (MRI). This aims compare field predictions...
Transcranial ultrasound stimulation (TUS) is an emerging non-invasive neuromodulation technique capable of manipulating both cortical and subcortical structures with high precision. Conducting experiments involving humans necessitates careful planning acoustic thermal simulations. This essential to adjust for bone interference the beam's shape trajectory ensure TUS parameters meet safety requirements. T1- T2-weighted, along zero-time echo (ZTE) magnetic resonance imaging (MRI) scans 1 mm...

People with Parkinson's disease often exhibit improvements in motor tasks when exposed to external sensory cues. While the effects of different types cues on functions have been widely studied, underlying neural mechanism these and potential alter cortical activity patterns functional connectivity areas are still unclear. This study aims compare changes oxygenated haemoglobin, deoxygenated haemoglobin correlations among regions interest during wrist movement under stimulus conditions between...
Abstract Introduction: Transcranial focused ultrasound is an emerging non-invasive neuromodulation technique that can reach subcortical targets in the human brain. However, skull degrade focusing of FUS beam. Modeling predict effects bone and inform corrective actions. This study reports degree mistargeting observed when deep brain structures without subject-specific corrections. Methods: A front-end application called BabelBrain (based on https://github.com/ProteusMRIgHIFU/BabelViscoFDTD...
