Neuronal correlates of the visually elicited escape response of the crab Chasmagnathus upon seasonal variations, stimuli changes and perceptual alterations
When confronted with predators, animals are forced to take crucial decisions such as the timing and manner of escape. In the case of the crab Chasmagnathus, cumulative evidence suggests that the escape response to a visual danger stimulus (VDS) can be accounted for by the response of a group of lobu...
