Embodied Organization of Octopus vulgaris Morphology, Vision, and Locomotion
- BiologyFront. Physiol.
The evolved control algorithms of the arms in goal directed movement and locomotion highlights control strategies that seem to overcome the need for central representation of the body parts in the central brain.
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.
Octopus vulgaris: An Alternative in Evolution.
- BiologyResults and problems in cell differentiation
An overview of some of the winning evolutionary inventions that octopus puts in place such as the capacity to see color, smell by touch, edit own genes, and rejuvenate own brain are provided.
How Nervous Systems Evolve in Relation to Their Embodiment: What We Can Learn from Octopuses and Other Molluscs
It is proposed that the embodied organization approach, developed by roboticists to design efficient autonomous robots, is useful for understanding the evolution and development of the efficient adaptive interaction of animals with their environment, using the octopus as the leading example.

What is in an octopus's mind?
- BiologyAnimal Sentience
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.
Where Is It Like to Be an Octopus?
- BiologyFrontiers in Systems Neuroscience
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.
Characterization of the Brain of the Red Mayan Octopus (Octopus maya Voss and Solis, 1966)
- BiologyJournal of Evolutionary Biochemistry and Physiology
This study characterized the morphology of 30 lobes in the brain of O. maya from young and adult specimens and the cells that constitute the connectivity pathways between these regions and observed that some lobes related to somatosensory memory have low cell density and a simpler morphology than that of adult specimens.
The vertical lobe of cephalopods: an attractive brain structure for understanding the evolution of advanced learning and memory systems
- BiologyJournal of Comparative Physiology A
It is shown that the cephalopod vertical lobe (VL) provides a good system for assessing the level of evolutionary convergence of the function and organization of neuronal circuitry for mediating learning and memory in animals with complex behavior and the properties of the neurons, neurotransmitters, neuromodulators and mechanisms of long-term potentiation induction and maintenance are highly variable among different species.

How do octopuses use their arms?
- BiologyJournal of comparative psychology
A taxonomy of the movement patterns of the 8 flexible arms of octopuses is constructed, which appears to be based on radial symmetry, relative equipotentiality of all arms, relative independence of each arm, and separability of components within the arm.
Organization of Octopus Arm Movements: A Model System for Studying the Control of Flexible Arms
- BiologyThe Journal of Neuroscience
It is proposed that this strategy reduces the immense redundancy of the octopus arm movements and hence simplifies motor control.
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.
Dynamic mimicry in an Indo–Malayan octopus
- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences
It is revealed that the ‘mimic octopus’ emerges during daylight hours to forage on sand substrates in full view of pelagic fish predators, allowing it to enhance further the benefits of mimicking toxic models by employing mimicry according to the nature of perceived threats.

Neuromuscular system of the flexible arm of the octopus: physiological characterization.
- BiologyJournal of neurophysiology
The lack of significant electrical coupling between muscle fibers and the indications for the small size of the motor units suggest that the neuromuscular system of the octopus arm has evolved to ensure a high level of precise localization in the neural control of arm function.
Neurobiology: Motor control of flexible octopus arms
It is shown that when the octopus uses one of its long and highly flexible arms to transfer an object from one place to another, it employs a vertebrate-like strategy, temporarily reconfiguring its arm into a stiffened, articulated, quasi-jointed structure, indicating that an articulated limb may provide an optimal solution for achieving precise, point-to-point movements.
