A novel pulse-current waveform circuit for low-energy consumption and low-noise transcranial magnetic stimulation.
Front Neurosci
January 2025
School of Electronic Information and Communications, Huazhong University of Science and Technology, Wuhan City, China.
Introduction: Transcranial magnetic stimulation (TMS) is widely used for the noninvasive activation of neurons in the human brain. It utilizes a pulsed magnetic field to induce electric pulses that act on the central nervous system, altering the membrane potential of nerve cells in the cerebral cortex to treat certain mental diseases. However, the effectiveness of TMS can be compromised by significant heat generation and the clicking noise produced by the pulse in the TMS coil.

Background: Amphetamines possess sympathomimetic properties that can affect cerebral vasculature though conflicting reports exist about their effect on vasospasm risk and clinical outcomes in aneurysmal subarachnoid hemorrhage. This study aimed to characterize the impact of recent amphetamine use on vasospasm development in aneurysmal subarachnoid hemorrhage as well as neurological outcomes.
Methods: We retrospectively screened 441 consecutive patients admitted with a diagnosis of subarachnoid hemorrhage who underwent at least one cerebral digital subtraction angiogram.
Effects of transcranial photobiomodulation on fine motor skills in boccia para-athletes.
Photochem Photobiol
January 2025
Laboratory of Lasers, Faculdade São Leopoldo Mandic, Campinas, Brazil.
This study investigated the effects of transcranial photobiomodulation (t-PBM) on para-athletes' manual dexterity and intralimbal coordination. Six para-athletes from a Boccia Team participated. t-PBM was administered using a LED helmet with 204 LEDs (660 and 850 nm) emitting 10 mW each, delivering 9 J/cm per LED during 15-min sessions three times a week.

School of Health and Human Sciences, Indiana University Indianapolis Indianapolis IN USA.
Most activities of daily life involve some degree of coordinated, bimanual activity from the upper limbs. However, compared to single-handed movements, bimanual movements are processed, learned, and controlled from both hemispheres of the brain. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that enhances motor learning by modulating the activity of movement-associated brain regions.

Electronic address:
Background: Reliable language mappings require sufficient language skills. This study evaluated whether linguistic task properties impact feasibility and reliability of navigated transcranial magnetic stimulation (nTMS)-based language mappings in aphasic glioma patients.
Methods: The effect of linguistic complexity on naming accuracy during baseline testing without stimulation and on the number of errors during nTMS was evaluated for 16 moderately and 4 severely expressive aphasic patients.
