Echolocation
in their length can quantitatively explain the dynamic range of all helical and non-helical cell geometries. The purified, detergent insoluble cytoskeleton complex from spiroplasmas contains over ten proteins, the main one being a 59 kDa product of the fib gene with no known prokaryotic or eukaryotic homologs. Infectivity in spiroplasmas is governed by an unusual lipoprotein, spiralin, which co...
متن کاملApical seal versus coronal seal
the results of the initial study. It was concluded that the apical fluids, with their primary source being blood serum, diffuse into the empty canal spaces, stagnate, undergo degradation and then act as a physicochemical irritant when they diffuse back into periapical tissues. In support of this theory of stagnation, in 1955 Dow and Ingle showed that the majority of the endodontic failures were...
متن کاملNeural correlates of motion processing through echolocation, source hearing, and vision in blind echolocation experts and sighted echolocation novices.
We have shown in previous research (Thaler L, Arnott SR, Goodale MA. PLoS One 6: e20162, 2011) that motion processing through echolocation activates temporal-occipital cortex in blind echolocation experts. Here we investigated how neural substrates of echo-motion are related to neural substrates of auditory source-motion and visual-motion. Three blind echolocation experts and twelve sighted ech...
متن کاملCognitive Abilities in Human Echolocation
The human ability to echolocate differs between individuals. Blind perform significantly better then sighted. There is very limited research on psychological factors underlying this ability. This study is based on earlier research by Schenkman and Nilsson (2010). The research questions in the present study were whether blind individuals perform better then sighted on general cognitive tasks, if...
متن کاملNeurobiology of echolocation in bats.
Echolocating bats (sub-order: Microchiroptera) form a highly successful group of animals, comprising approximately 700 species and an estimated 25% of living mammals. Many echolocating bats are nocturnal predators that have evolved a biological sonar system to orient and forage in three-dimensional space. Acoustic signal processing and vocal-motor control are tightly coupled, and successful ech...
