The peduncle lobe of Octopus, a centre concerned with regulating motor behaviour primarily on the basis of visual cues, though it also receives a “labyrinthine” or statocyst input, has been examined for the first time in the electron microsope. In the lower part of the lobe, the basal zone, there are large “motor” cells up to 20 μm across with a rounded, pale nucleus and a large perikaryon; there are also smaller cells, 4‐10 μm in diameter with a dark irregularly‐shaped nucleus. The latter… Expand
The central afferent and efferent organization of the gravity receptor system of the statocyst of Octopus vulgaris
TLDR
The results imply that processing of static information occurs in many areas of the Octopus CNS, and is much more complex than previously thought. Expand
Distribution of immunoreactive somatostatin (ISRIF) in the nervous system of the squid, Loligo pealei

TLDR
Examination of the distribution of immunoreactive‐like SRIF‐containing elements in the nervous system of the cephalopod mollusk Loligo pealei or the Woods Hole squid found ISRIF was localized by light immunocytochemistry in sections of the squid—optic lobe, circumesophageal ganglia—and in stellate ganglion. Expand
Galanin-immunoreactive neuronal system and colocalization with serotonin in the optic lobe and peduncle complex of the octopus (Octopus vulgaris)
TLDR
The association of galanin-like substance and 5-HT with the visual system of octopus is suggested and that the main form of the octopus Gal-IR might have a different molecular weight from vertebrate galanins. Expand
Evidence for visual mapping in the peduncle lobe of octopus

The first use of horseradish peroxidase in the central nervous system of a cephalopod revealed apparent topographic connections between optic and peduncle lobes in octopus. Optic lobe efferent fibersExpand
Quantitative differences among the brains of cephalopods
TLDR
The relative sizes of 30 lobes of the brains of 63 species of cephalopods have been compared and it is found that the optic lobes are larger in decapods than in octopods from comparable depths and are especially large in deep-sea decapods. Expand
NADPH-diaphorase containing cells and fibers in the central nervous system of squid, Loligo bleekeri keferstein.
TLDR
There may be at least two distinct neural systems, the motor control system and the visual information processing system, which use nitric oxide as a transmitter or modulator in the squid central nervous system. Expand
The statocyst-oculomotor system of octopus vulgaris: extraocular eye muscles, eye muscle nerves, statocyst nerves and the oculomotor centre in the central nervous system
TLDR
The statocyst-oculomotor system of Octopus includes two pathways from the statocySt equilibrium receptor organs to the motoneurons of the eyes: one direct pathway, and another indirect path via higher integrative centres where visual information about movement is combined with that coming from thestatocysts. Expand
The Cerebellum
The cerebellum (Latin for “little brain”) is a region of the brain that plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language,Expand
The anterior basal lobe and control of prey-capture in the cuttlefish (Sepia officinalis)
TLDR
Lesions to the anterior basal lobe were made by an electrolytic method and the animals were allowed to attack their prey in an unrestricted way so that motor defects, functional recovery and the emergence of new adaptative behavioural strategies could be studied. Expand
The Octopus: A Model for a Comparative Analysis of the Evolution of Learning and Memory Mechanisms
TLDR
The emerging results suggest that a convergent evolutionary process has led to the selection of vertebrate-like neural organization and activity-dependent long-term synaptic plasticity in octopuses and vertebrates, and suggests the importance of the shared properties for the mediation of learning and memory.

TLDR
Anatomical, physiological and behavioural evidence suggest that the nervous part of the peduncle complex, probably the ped uncle lobe alone, is part of a motor-control system that regulates motor activity on the basis of visual information derived from the optic lobe. Expand

TLDR
Electron microscopy supports Young's suggestion that the superior frontal and interconnected vertical lobe systems constitute a loop which could sustain a positive feed-back mechanism while the 'pain' (nocifensor) input could exert a suppressor (inhibitory) effect on the loop by its action on the large cells.

TLDR
It is suggested that the variety of shapes of the dendritic trees within the optic lobes provides the elements of the coding system by which visual input is classified. Expand

TLDR
The optic nerve fibres project on to the optic lobe in a regular manner, being precisely re-assorted after passing through a chiasma, and there is a regular mapping of the visual field throughout much of the system. Expand
The nervous system of Loligo, III. Higher motor centres: the basal supraoesophageal lobes
TLDR
The control of eye movements is thus organized in cephalopods in the same way as it is in vertebrates' there is a direct static input to the oculomotor centre, which also receives indirect static influences combined with visual ones, by way of the cerebellum in vertebrate, or basal and peduncle lobes in cEPhalopod.

Is the cerebellar cortex a biological clock in the millisecond range?
TLDR
In any particular region of the cerebellar cortex, the ratio, volume, and number of afferent and efferent fibers is approximately constant, which can be deduced from measurements of the surface of the molecular layer in a certain region and the cross section of the corresponding white core. Expand

TLDR
Evidence from all four sets of data suggest that the optic lobes are the prime instigators of motor ‘commands’ following visual stimuli and that the peduncle lobes is a subordinate system that modifies these commands, on the basis of changing visual cues. Expand

TLDR
The peduncle lobe shows a pattern of fluorescence associated with the ‘spine’ which is also exhibited by structures within the basal lobes which have recently been found to possess striking cytoarchitectural similarities to the ped uncle lobe. Expand
Electron microscopy of the glio-vascular organization of the brain of octopus
TLDR
The observation that the lobes of the octopus brain are permeated with extracellular tunnels containing smooth muscle fibres is of special importance, but it still needs to be determined whether or not the muscle cells in the tunnels of the neuropil actively contract and massage the Neuropil to facilitate metabolic and other exchanges.

TLDR
The numerical, metrical and topological parameters of the divergence from mossy fibers through granule cells and parallel fibers, as well as those of the convergence at granule cell and Purkinje cell level can be established with reasonable accuracy. Expand
