Prepontine non-giant neurons drive flexible escape behavior in zebrafish [PDF]

open access: yes, 2019
Many species execute ballistic escape reactions to avoid imminent danger. Despite fast reaction times, responses are often highly regulated, reflecting a trade-off between costly motor actions and perceived threat level.

Ultrasonic distance detection for a closed-loop spinal cord stimulation system [PDF]

open access: yes, 1997
When stimulating the spinal cord at a constant strength, the current density in the spinal cord and thus the effects on chronic, intractable pain and vascular insufficiency will change with body position, due to the varying separation of the spinal cord ...

Processing acoustic change and novelty in newborn infants [PDF]

open access: yes, 2007
Research on event-related potential (ERP) correlates of auditory deviance-detection in newborns provided inconsistent results; temporal and topographic ERP characteristics differed widely across studies and individual infants.

Suppression of Acoustic Input by Thalamic Stimulation.

open access: yesExperimental Biology and Medicine, 1958
1. Electrical responses to clicks were recorded from the ventral cochlear nucleus in curarized cats, and the effect thereon of brain stem repetitive stimulation was investigated (stereotaxic method). 2. Clear-cut inhibition of the cochlear nucleus response to click was recorded when a critically-localized region of the posterior diencephalon was ...

Effects of ultrasound on Transforming Growth Factor-beta genes in bone cells [PDF]

open access: yes, 2005
Therapeutic ultrasound (US) is a widely used form of biophysical stimulation that is increasingly applied to promote fracture healing. Transforming growth factor-beta (TGF-beta), which is encoded by three related but different genes, is known to play a ...

Acoustic enhancement of sleep slow oscillations in mild cognitive impairment

open access: yesAnnals of Clinical and Translational Neurology, 2019
Objective Slow‐wave activity (SWA) during sleep is reduced in people with amnestic mild cognitive impairment (aMCI) and is related to sleep‐dependent memory consolidation.

Mechanisms underlying the production of carapace vibrations and associated waterborne sounds in the American lobster, Homarus americanus [PDF]

open access: yes, 2005
American lobsters produce carapace vibrations, which also lead to waterborne acoustic signals, by simultaneously contracting the antagonistic remotor and promotor muscles located at the base of the second antenna.

Stimulated Brillouin scattering by surface acoustic waves in lithium niobate waveguides [PDF]

open access: yes, 2023
We numerically demonstrate that Lithium Niobate on Insulator (LNOI) waveguides may support confined short-wavelength surface acoustic waves that interact strongly with optical fields through backward stimulated Brillouin scattering in both $Z$ and $X$-cut orientation.
