Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [ 13 ] [ 14 ] though it does not appear that they assess prey animals based on their body temperature. [ 15 ]
Many empirical studies have found evidence for the theory. Primates, including humans, are able to quickly detect snakes. [6] [7] Some studies have found that humans can detect snake images before subjective visual perception. [8] However, the pre-conscious detection of snake stimuli is still under debate by the scientific community. [9]
Lynne A. Isbell (born 1955) is an American ethologist and primatologist, professor of anthropology at the University of California, Davis.. Isbell has served as president of the American Society of Primatologists and is the originator of the snake detection theory, which suggests that snakes have contributed to the evolution of the visual system of primates.
The higher the altitude, the less dense the atmosphere and the less infrared radiation it absorbs - especially at longer wavelengths. The effect of reduction in friction between air and aircraft does not compensate for the better transmission of infrared radiation. Therefore, infrared detection ranges are longer at high altitudes.
President-elect Donald Trump suggested that Robert F. Kennedy Jr., his pick to run Health and Human Services, will investigate supposed links between autism and childhood vaccines, a discredited ...
Activation of TRPV1-S channels in the TG may then suggest a similar mechanism (as seen in IR-sensing snakes) for how infrared sensing may work in vampire bats. Trigeminal nerves which innervate specialized temperature sensitive receptors on the nose-leaf may in turn activate TRPV1-S channels in the TG in response to infrared thermal radiation. [5]
