SUMMARY Cephalopods are an exceptional taxon for examining the competing influences of ecology and evolutionary history on brain and behaviour. Coleoid cephalopods (octopuses, cuttlefishes and squids) have evolved specialised brains containing dedicated learning and memory centres, and rely on plastic behaviours to hunt prey effectively and communicate intricate visual displays. Their closest living relative, the primitive nautilus, is the sole remnant of an ancient lineage that has persisted… 
A SYNTHETIC APPROACH TO THE STUDY OF LEARNING AND MEMORY IN CHAMBERED nautiluS L . ( CEPHALOPODA , NAUTILOIDEA )
– We apply the synthetic approach to the study of learning in the ancient cephalopod nautilus pompilius, l. as a way of understanding how the complex brain and behaviors may have evolved in its more
Flexible Spatial Orientation and Navigational Strategies in Chambered Nautilus
TLDR
Testing whether Nautilus pompilius could learn to navigate towards a goal location using either visual cues or motor responses indicates that animals relied both on proximate and distant visual cues to orient but did not use egocentric cues, a somewhat surprising finding given that nautilus spends most of its time in near darkness.
Foraging and scavenging in nautilus (Nautilus sp.) L. (Cl. Cephalopoda)
TLDR
It is shown that nautiluses display a stereotyped set of search postures in the wild, suggesting it is a natural and functional reflex in nautilus, and can be replicated under controlled conditions.
Ontogenetic and Experience-Dependent Changes in Defensive Behavior in Captive-Bred Hawaiian Bobtail Squid, Euprymna scolopes
TLDR
This study shows that captive bred juvenile and adult E. scolopes produce robust, repeatable defensive behaviors when placed in an exposed environment and presented with a visual threat, and suggests that the lack of long-term memory in adult squid may be related to their less escalated initial response to the mimic, and thus indicates less motivation to retain memory and not necessary inability to form memory.
Lost in phototransduction: a few facts and hypotheses on cephalopod photoresponse.
TLDR
A 92 kDa protein, which is homologous to the Drosophila transient receptor potential (TRP) gene, is the most likely mediator of light-induced currents in cephalopods and a number of models which explain the mechanism whereby cEPhalopod TRP channel is gated by light will be discussed.
Evidence of learning and memory in the juvenile dwarf cuttlefish Sepia bandensis.
TLDR
DanioVision can be used to assess multiple components of dynamic responses that are not measurable by direct observation alone and provide new evidence that strike inhibition is the product of learning, and not motor fatigue.

TLDR
This special issue arose from a conference entitled ‘Molluscan Neuroscience: Recent Advances and New Vistas’, which was held February 12th–15th, 2009, in Old San Juan, Puerto Rico and attracted about 100 participants and presents extremely interesting, provocative, and controversial views about how mollus can neuroscience fits into a general view of neuroscience.
The Evolution of Flexible Behavioral Repertoires in Cephalopod Molluscs
TLDR
Evidence is outlined that although competition with vertebrates has left a deep impression on the brains and behavior of cephalopods, the original reorganization of their complex brains from their molluscan ancestors might have been forged in ancient seas millions of years before the advent of bony fishes.
In Vivo Recording of Neural and Behavioral Correlates of Anesthesia Induction, Reversal, and Euthanasia in Cephalopod Molluscs
TLDR
It is demonstrated for the first time that two of the most commonly used agents in cephalopod general anesthesia, magnesium chloride and ethanol, are capable of producing strong and reversible blockade of afferent and efferent neural signal; thus they are genuine anesthetics, rather than simply sedating agents that render animals immobile but not insensible.

TLDR
It is shown that it is possible to demonstrate that a single neuron is a site of memory formation and storage for a form of associative learning in this lowly snail.
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
The evidence suggests that learning in cephalopods is not localized to certain layers or "grandmother cells" but is distributed with high redundance in serial networks, with recurrent circuits.
Evolution of the cephalopod head complex by assembly of multiple molluscan body parts: Evidence from Nautilus embryonic development
TLDR
The results demonstrate that the embryonic organs exhibit body plans that are primarily bilateral and antero‐posteriorly elongated at stereotyped positions, and suggest that extensions of the collar‐funnel compartment and free epidermal folds derived from multiple topological foot regions may play an important role in forming the head complex, which is thought to be an important feature during the body plan transition.
Three-dimensional odor tracking by Nautilus pompilius.
TLDR
Flume testing under dark conditions revealed that Nautilus could consistently detect and follow turbulent odor plumes to the source over distances up to 10 m, exhibiting two types of orientation behavior while sampling in three dimensions.

Short Communications: The Spectral Sensitivity of Nautilus Pompilius
TLDR
Spectral sensitivity of Nautilus was determined by means of their positive phototactic behaviour using the Y-maze, and the absolute sensitivity was estimated to be around 2 log units worse than for a typical deep-sea fish.
