There was no evidence of any detrimental effect other than middle ear discomfort. Tests of high-intensity infrasound on animals resulted in measurable changes, such as cell changes and ruptured blood vessel walls. Infrasound is one hypothesized cause of death for the nine Soviet hikers who were found dead at Dyatlov Pass in 1959. [55]
Infrasound sensitive fibers are found to be simple bipolar cells in the auditory ganglion with a diameter of 1.6-2.2 μm at the axon and 0.9-1.2 μm at the dendrites. [19] They originate in the apical end of the cochlea and they are located near fibers that transmit low frequency sounds in the acoustic range.
Vladimir Gavreau, born Vladimir Gavronsky (1904 – 1967), [1] was a French scientist making experiments on the biological effects of infrasound. Gavreau was born in Moscow . His interest in infrasonic waves first came about in his lab during the 1960s, when he and his lab assistants experienced pain in the ear drums and shaking lab equipment ...

Lindsay's Wheel of Acoustics, which shows fields within acoustics. Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.
And it really does change their developmental trajectory longer term.” That’s exactly what’s been worrying Desiree Wines, whose 3-year-old son Jibreel has autism, communication issues and ...
In fear conditioning, the main circuits that are involved are the sensory areas that process the conditioned and unconditioned stimuli, certain regions of the amygdala that undergo plasticity (or long-term potentiation) during learning, and the regions that bear an effect on the expression of specific conditioned responses. These pathways ...
