Neuroethology: Self-Recognition Helps Octopuses Avoid Entanglement
نویسندگان
چکیده
How an octopus performs complex movements of its eight sucker-studded arms without entanglement has been a mystery. A new study has found that self-recognition of the octopus's skin by its suckers inhibits reflexive grasping of its own arms, simplifying the mechanisms needed to generate intricate arm behavior.

Self-Recognition Mechanism between Skin and Suckers Prevents Octopus Arms from Interfering with Each Other
Controlling movements of flexible arms is a challenging task for the octopus because of the virtually infinite number of degrees of freedom (DOFs) [1, 2]. Octopuses simplify this control by using stereotypical motion patterns that reduce the DOFs, in the control space, to a workable few [2]. These movements are triggered by the brain and are generated by motor programs embedded in the periphera...
متن کاملOctopuses (Enteroctopus dofleini) recognize individual humans.
This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and respiration rates directly after each treatment. At the end of 2 weeks, a body pattern (a dark Eyebar) and 2...
متن کاملI Know My Neighbour: Individual Recognition in Octopus vulgaris
BACKGROUND Little is known about individual recognition (IR) in octopuses, although they have been abundantly studied for their sophisticated behaviour and learning capacities. Indeed, the ability of octopuses to recognise conspecifics is suggested by a number of clues emerging from both laboratory studies (where they appear to form and maintain dominance hierarchies) and field observations (oc...
متن کاملNeuroethological Approach to Understanding Intelligence
The neuroethology is an interdisciplinary study among artificial intelligence, biology and robotics to understand the animal behavior and its underlying neural mechanism. We argue that the neuroethological approach helps understand the general artificial intelli-
متن کاملSome Comments about the Object and Realization of Neutrality as Fair Treatment in Alan Patten’s Equal Recognition
In Equal Recognition, Alan Patten aims at providing a firm philosophical foundation to minority rights. The main problem with the usual multiculturalist arguments defending such rights is that they are based on controversial conceptions of culture that are at odds with liberal neutrality. To avoid such difficulty, Patten’s argument for strong cultural rights is based on a commitment to neutrali...
