Transcranial Alternating Current Stimulation with Sawtooth Waves: Simultaneous Stimulation and EEG Recording [PDF]

Frontiers in Human Neuroscience, 2016
Transcranial alternating current stimulation (tACS) has until now mostly been administered as an alternating sinusoidal wave. Despite modern tACS stimulators being able to deliver alternating current with any arbitrary shape there has been no systematic exploration into the relative benefits of different waveforms. As tACS is a relatively new technique

Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, EarlyView.
ABSTRACT The blood‐brain barrier (BBB) renders the delivery of nanomedicine in the brain ineffective and the detection of circulating disease‐related DNA from the brain unreliable. Here, we demonstrate that microbubble‐enhanced focused ultrasound (MB‐FUS) mediated BBB opening, supported by large‐data models predict sonication regimens for safe and ...

Wearable Metamaterials with Embodied Intelligence for Programmable Control of Human Limbs Tremor

Advanced Intelligent Systems, EarlyView.
Resulting from alternating muscle contractions, tremors can severely limit human ability to perform everyday tasks like walking or talking, due to their disruptive nature. Medication and surgery may not always effectively address tremor control. A wearable device embodying programmable smart metamaterials with adaptable intelligence to meet the demand ...

Slow-Frequency Pulsed Transcranial Electrical Stimulation for Modulation of Cortical Plasticity based on Reciprocity Targeting with Precision Electrical Head Modeling

Frontiers in Human Neuroscience, 2016
In pain management as well as other clinical applications of neuromodulation, it is important to consider the timing parameters influencing activity-dependent plasticity, including pulsed versus sustained currents, as well as the spatial action of ...

Closed-loop transcranial alternating current stimulation of slow oscillations

Current Directions in Biomedical Engineering, 2015
Transcranial alternating current stimulation (tACS) is an emerging non-invasive tool for modulating brain oscillations. There is evidence that weak oscillatory electrical stimulation during sleep can entrain cortical slow oscillations to improve the ...

Managing Dystonia in Partington Syndrome

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Bilateral focal hand dystonia is an almost pathognomonic sign of Partington syndrome, frequently accompanied by intellectual disability and oromotor dyspraxia. However, a few studies have focused on the treatment of this focal dystonia, making patient management uncertain.
