Invertebrate Vision: Peripheral Adaptation to Repeated Object Motion
Visual systems adapt rapidly to objects moving repeatedly within the visual field, because such objects are likely irrelevant. In the crab, the neural switch for such adaptation has been found to take place at a surprisingly early stage of the visual processing pathway.
متن کاملInvertebrate Perception: Measuring Depth Intervals through Path Integration and Vision
A foraging fiddler crab can estimate how close a potential intruder is from its burrow entrance, even when the entrance in the sand is invisible to the crab. Recent work shows that, to assess this depth interval, crabs combine information from vision and path integration in an unusual manner.
متن کاملPoint process analysis of noise in early invertebrate vision
Noise is a prevalent and sometimes even dominant aspect of many biological processes. While many natural systems have adapted to attenuate or even usefully integrate noise, the variability it introduces often still delimits the achievable precision across biological functions. This is particularly so for visual phototransduction, the process responsible for converting photons of light into usab...
متن کاملCurrent advances in invertebrate vision: insights from patch-clamp studies of photoreceptors in apposition eyes.
Traditional electrophysiological research on invertebrate photoreceptors has been conducted in vivo, using intracellular recordings from intact compound eyes. The only exception used to be Drosophila melanogaster, which was exhaustively studied by both intracellular recording and patch-clamp methods. Recently, several patch-clamp studies have provided new information on the biophysical properti...
