Use of Peripheral Sensory Information for Central Nervous Control of Arm Movement by Octopus vulgaris

What is in an octopus's mind?

The actions of octopuses can be domain general, with flexible problem-solving strategies, enabling them to survive “by their wits” in a challenging and variable environment.

How Does the Octopus Efficiently Control Its Flexible, Multi-Armed Body?

The interesting mechanisms octopi have developed to allow control over their unique bodies are revealed.

Feel the light: sight-independent negative phototactic response in octopus arms

This work shows that in response to illumination, the arm tip reacts in a reflex-like manner, folding in and moving away from the light beam, and proposes that the phototaxis is a means for protecting the arms in an instinctive manner from potential daytime predators that could identify the worm-like tips as food.

Octopus Motor Control-Oxford Research Encyclopedia of Neuroscience

Studies will be summarized to show that the amazing behavioral motor abilities of the octopus are achieved through a special embodied organization of its flexible body, unusual morpholo­ gy, and a unique central and peripheral distribution of its extremely large nervous system.

Lessons for Robotics From the Control Architecture of the Octopus

The neuroanatomical organization of the octopus peripheral nervous system is described and how this distributed neural network is specialized for effectively mediating decisions made by the central brain and the continuous actuation of limbs possessing an extremely large number of degrees of freedom is discussed.

Where Is It Like to Be an Octopus?

This manuscript explores the possibility that the octopus arm is capable of supporting an idiosyncratic field of consciousness, and investigates the likelihood that there is something it is like to be anOctopus arm.

This review highlights the key structure–function relationships of octopus arms and suckers, and how they have inspired the field of soft robotics.

New Insights on the Control and Function of Octopus Suckers

Sucker pull‐off forces are measured in Octopus bimaculoides when the arm is intact, amputated, and amputated with the suckers punctured, indicating that the primary mechanism for sucker attachment is suction, and is less dependent on adhesion.

The autonomous arms of the octopus

Inspired by the octopus, roboticists are working to incorporate decentralized control systems into soft robotic arms, demonstrating how little input from the central brain is needed.

Octopuses Use a Human-like Strategy to Control Precise Point-to-Point Arm Movements

Octopus sucker-arm coordination in grasping and manipulation*

Investigation of octopuses' use of suckers under controlled, reproducible laboratory conditions shows results consistent with the known neural organization of the octopus arm and also with complex sucker-arm coordination in the performance of manipulation tasks.

Organization of Octopus Arm Movements: A Model System for Studying the Control of Flexible Arms

It is proposed that this strategy reduces the immense redundancy of the octopus arm movements and hence simplifies motor control.

Control of Octopus Arm Extension by a Peripheral Motor Program

It is shown that arm extensions can be evoked mechanically or electrically in arms whose connection with the brain has been severed, suggesting that the basic motor program for voluntary movement is embedded within the neural circuitry of the arm itself.

A novel preparation is described that allows analysis of the peripheral nervous system of the octopus arm and its interaction with the muscular and mechanosensory elements of the arm’s intrinsic muscular system.

FUNCTIONAL MORPHOLOGY OF THE NEUROMUSCULAR SYSTEM OF THE oCtoPuS VulGariS ARM

The octopus arm's neuromuscular system is characterized using light and elec- tron microscopy to examine the organization of muscle groups and pattern of innervation, and it is shown that the muscle cells are innervated via localized synaptic junctions.
