Transcranial Ultrasound Stimulation of Internal Globus Pallidus Region and Motor Cortex in Parkinson's Disease Open
Background Many patients with Parkinson's disease (PD) have motor impairments despite dopaminergic therapy. Low‐intensity transcranial ultrasound stimulation (TUS) is a non‐invasive neuromodulation method with high spatial precision. The e…

Cortical modulations before lower limb motor blocks are associated with freezing of gait in Parkinson’s disease: an EEG source localization study Open
Right inferior parietofrontal structures are implicated in PD-FOG. The predominant changes were in the alpha rhythm, which increased before LLMB and with LLMB severity. Similar connectivity was observed for LLMB and stops between the right…

Inferring cognitive state underlying conflict choices in verbal Stroop task using heterogeneous input discriminative-generative decoder model Open
Objective . The subthalamic nucleus (STN) of the basal ganglia interacts with the medial prefrontal cortex (mPFC) and shapes a control loop, specifically when the brain receives contradictory information from either different sensory syste…

Robust Removal of Slow Artifactual Dynamics Induced by Deep Brain Stimulation in Local Field Potential Recordings using SVD-based Adaptive Filtering Open
Deep brain stimulation (DBS) is widely used as a treatment option for patients with movement disorders. In addition to its clinical impact, DBS has been utilized in the field of cognitive neuroscience wherein the answers to several fundame…

Multi-modal investigation of transcranial ultrasound-induced neuroplasticity of the human motor cortex Open
The findings from this study provide novel insights into the neurophysiologic basis of TUS-mediated neuroplasticity and point to the involvement of regions within the motor network in mediating this sustained response. Future studies may f…

Fronto-subthalamic phase synchronization and cross-frequency coupling during conflict processing Open
Growing evidence suggests that both the medial prefrontal cortex (mPFC) and the subthalamic nucleus (STN) play crucial roles in conflict processing, but how these two structures coordinate their activities remains poorly understood. We sim…

Acute low frequency dorsal subthalamic nucleus stimulation improves verbal fluency in Parkinson's disease Open
Here, we provide evidence that dorsal STN theta stimulation may improve verbal fluency, suggesting a potential possibility of integrating theta stimulation into current DBS paradigms to improve cognitive outcomes.

Plastic changes in the brain after human hand allotransplantation Open
Vascularized composite allotransplantation of the hand is technically feasible and is the only option to recover a lost hand after amputation. However, universal acceptance of this surgical reconstruction as a medical standard of care has …
