Auditory Information Accelerates the Visuomotor Reaction Speed of Elite Badminton Players in Multisensory Environments

Frontiers in Human Neuroscience, 2021
Although vision is the dominating sensory system in sports, many situations require multisensory integration. Faster processing of auditory information in the brain may facilitate time-critical abilities such as reaction speed however previous research ...

The influence of the scene on linguistic expectations: Evidence from cross-model priming in visual worlds [PDF]

, 2007
- Numerous studies of utterance mediated gaze in visual scenes have demonstrated that sentence processing is not only incremental but also eager: During processing, listeners form expectations about upcoming arguments and make anticipatory eye movements ...

Ready ... Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time [PDF]

, 2009
What happens when the brain awaits a signal of uncertain arrival time, as when a sprinter waits for the starting pistol? And what happens just after the starting pistol fires? Using functional magnetic resonance imaging (fMRI), we have discovered a novel

Light‐Actuated Fiber‐Climbing Inchworm Robot Toward Endoluminal Navigation

Advanced Functional Materials, EarlyView.
A kirigami‐inspired soft inchworm robot harnesses optical energy from a customized side‐emitting optical fiber, guaranteeing its propulsion along the fiber body. The wavelength‐selective responsiveness of dye‐functionalized liquid crystal elastomers and the application of temporal illumination patterns enable sequential control of robot components. The

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

, 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.

GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

Advanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

A study on measurement of auditory reaction time.

Nippon Jibiinkoka Gakkai Kaiho, 1990
In order to determine auditory reaction time, different test methods for central conducting modes (simple reaction, choice reaction, simultaneous reaction and time lag reaction) were carried out on normal subjects. As test sounds, pure tone, white noise and Japanese vowels were employed. The following results were obtained.

Fibronectin1‐Expressing Subicular Circuits Selectively Govern the Retrieval of Novel Object Recognition

Advanced Science, EarlyView.
Fibronectin 1 (FN1)‐expressing subicular subpopulations encode novel object preference and selectively govern retrieval of novel object recognition (NOR) via affecting excitability of entorhinal‐projecting circuit through large conductance Ca2+‐activated potassium (BK) channel. ABSTRACT Novel object recognition (NOR), referring to the cognitive ability
