Exploring Background Noise With a Large‐N Infrasound Array: Waterfalls, Thunderstorms, and Earthquakes [PDF]

Geophysical Research Letters, 2023
Ambient infrasound noise contains an abundance of information that is typically overlooked due to limitations of typical infrasound arrays. To evaluate the ability of large‐N infrasound arrays to identify weak signals hidden in background noise, we ...

Inhibition of astroglial hemichannels ameliorates infrasonic noise induced short-term learning and memory impairment [PDF]

Behavioral and Brain Functions, 2023
As a kind of environmental noise, infrasonic noise has negative effects on various human organs. To date, research has shown that infrasound impairs cognitive function, especially the ability for learning and memory.

Zebrafish aversion to infrasound in an open field test [PDF]

Frontiers in Behavioral Neuroscience, 2023
Aquatic species are capable of detecting infrasound (sub-20 Hz frequencies) which may be a source of anthropogenic pollution and have a detrimental impact on the environmental fitness of fish. Infrasound is generated by infrastructure, producing acoustic

Infrasound detection of approaching lahars. [PDF]

Sci Rep, 2023
AbstractInfrasound may be used to detect the approach of hazardous volcanic mudflows, known as lahars, tens of minutes before their flow fronts arrive. We have analyzed signals from more than 20 secondary lahars caused by precipitation events at Fuego Volcano during Guatemala’s rainy season in May through October of 2022.

Can Environmental Enrichment Mitigate Cell Apoptosis in the Central Nervous System Under Adverse Health Conditions? A Systematic Review. [PDF]

Clin Transl Sci
ABSTRACT To summarize the available evidence in the literature regarding the effects of exposure to an enriched environment (EE) on the modulation of apoptotic markers in central tissue of rodents under unfavorable conditions. Searches were conducted in three databases: PubMed/Medline (70 articles), Scopus (65 articles), and EMBASE (128 articles), all ...
