No evidence that severity of stroke in internal carotid occlusion is related to collateral arteries [PDF]

, 2006
Background/AimThe neurological effects of internal carotid artery (ICA) occlusion vary between patients. The authors investigated whether the severity of symptoms in a large group of patients with ipsilateral or/and contralateral ICA occlusion at ...

A Multielectrode Array-Based Recording System for Analyzing Ultrasound-Driven Neural Responses in Brain Slices in vitro

Frontiers in Neuroscience, 2022
Ultrasound stimulation is expected to be useful for transcranial local and deep stimulation of the brain, which is difficult to achieve using conventional electromagnetic stimulation methods.

Application of transcranial brain stimulation in dementia

Tzu Chi Medical Journal, 2023
The number of patients with dementia grows rapidly as the global population ages, which posits tremendous health-care burden to the society. Only cholinesterase inhibitors and a N-methyl-D-aspartate receptor antagonist have been approved for treating ...

Vasospasm is a significant factor in cyclosporine-induced neurotoxicity: Case report

BMC Neurology, 2010
Background The aetiology of central nervous system lesions observed in cerebral cyclosporine neurotoxicity remains controversial. Case presentation We report a 48-year-old woman with a non-severe aplastic anaemia who presented with stroke-like episodes ...

Optically-generated focused ultrasound for noninvasive brain stimulation with ultrahigh precision

Light: Science & Applications, 2022
We report optically-generated focused ultrasound for non-invasive brain stimulation with ultrahigh precision of 83 µm, which is two orders of magnitude smaller than that of conventional transcranial focused ultrasound.

Increased anatomical specificity of neuromodulation via modulated focused ultrasound. [PDF]

PLoS ONE, 2014
Transcranial ultrasound can alter brain function transiently and nondestructively, offering a new tool to study brain function now and inform future therapies. Previous research on neuromodulation implemented pulsed low-frequency (250-700 kHz) ultrasound

Robot-assisted image-guided transcranial magnetic stimulation for somatotopic mapping of the motor cortex: a clinical pilot study. [PDF]

, 2009
Shape and exact location of motor cortical areas varies among individuals. The exact knowledge of these locations is crucial for planning of neurosurgical procedures.

Dual-Probe Transcranial Full-Waveform Inversion: A Brain Phantom Feasibility Study

, 2023
Objective Despite being a low-cost, portable and safe medical imaging technique, transcranial ultrasound imaging is not used widely in adults because of the severe degradation and distortion of signals caused by the skull.
