Conventional techniques for the noninvasive measurement of brain activity involve critical limitations in spatial or temporal resolution. Here, we propose the method for noninvasive brain function measurement with high spatiotemporal resolution using optical signals. We verified that diffused near-infrared light penetrating through the upper jaw and into the skull, which we term as optoencephal...

Somatosensory evoked potentials (SSEPs) and motor evoked potentials (MEPs) are non-invasive neurophysiological tests that reflect the functional integrity of sensory and motor pathways. Despite their extensive use and description in human medicine, reports in veterinary medicine are scarce. SSEPs are obtained via peripheral stimulation of sensory or mixed nerves; stimulation induces spinal and ...

The retrospective study was designed to compare the diagnostic value of computed radiography, magnetic resonance imaging, computed tomography, and electrodiagnostic procedures like brainstem evoked potentials and somatosensory evoked potentials in cervical spinal cord diseases in dogs; including wobbler syndrome, intervertebral disc disease, trauma, neoplasma, and syringomelia. Thirty-one dogs ...

The central theory of headache was investigated by examining the amplitude of the somatosensory evoked potential (SSEP) in headache sufferers and headache-free controls. The P1-N1 amplitude was found to be greater, and to increase more rapidly with increasing stimulus intensity, for headache subjects than for controls. The N1-P2 amplitude was also found to be larger for headache subjects than f...

Intraoperative neurophysiological monitoring (IONM) during corrective spinal surgery is widely used. Because of the possible interference with the recording of evoked potentials by inhalational anesthetics, total intravenous anesthetic (TIVA) regimens have been advocated. TIVA regimens may be difficult to use in pediatric populations due to metabolic factors. We report on the results of multimo...

This paper presents direct numerical simulations (DNS) on unsteady turbulent flow in a vibrating low-pressure turbine blade cascade to predict the flutter instabilities and explores effects of oscillations structure separation point. The spectral/hp element method is employed for three-dimensional domain. enables capturing more details about vortex generations compared URANS methods. can aid un...

Abstract Introduction Establishing neurological prognosis after out-of-hospital cardiac arrest (OHCA) safely and early in those patients who remain a coma at 72 hours of admission. Purpose To analyze the prognostic performance neuron-specific enolase (NSE), Somatosensory evoked potentials (SSEPs) electroencephalogram (EEG) these patients. Methods Prospective observational study, including all O...
