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.
Combined with the natural spread in thresholds within a population, its effect may be that a very low-frequency sound which is inaudible to some people may be loud to others. [citation needed] One study has suggested that infrasound may cause feelings of awe or fear in humans.
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.
There is a belief that infrasound can cause symptoms, including tinnitus, stress, fatigue, memory loss, attention deficit, vertigo, migraines and sleep deprivation. [ 4 ] A panel of experts commissioned by the Massachusetts Department of Environmental Protection concluded in 2012 that "there is not an association between noise from wind ...
Death anxiety can mean fear of death, fear of dying, fear of being alone, fear of the dying process, etc. [29] Different people experience these fears in differing ways. There continues to be confusion on whether death anxiety is a fear of death itself or a fear of the process of dying. [30]
G. Stanley Hall, the nineteenth-century founder of the American Journal of Psychology and the first president of the American Psychological Association, described fear as “the anticipation of ...
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device.
People who believe they have lived life to the "fullest" typically do not fear death. Death anxiety is multidimensional; it covers "fears related to one's own death, the death of others, fear of the unknown after death, fear of obliteration, and fear of the dying process, which includes fear of a slow death and a painful death".
