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.
[13] [14] Their research led them to conclude that infrasound at or around a frequency of 19 Hz, [2] [11] [15] has a range of physiological effects, including feelings of fear and shivering. [8] Though this had been known for many years, Tandy and Lawrence were the first people to link it to ghostly sightings.
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 ...
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 ...
Artificial intelligence's recent rise to the forefront of business has left most office workers wondering how often they should use the technology and whether a computer will eventually replace them.
