The survey and reference assisted assembly of the Octopus vulgaris genome
The data give a first quantitative glimpse into the rate of coding and non-coding regions and support the view that hundreds of novel genes may have arisen independently despite the close phylogenetic distance.
Cephalopod Behavior: From Neural Plasticity to Consciousness
It is proposed that cephalopods - particularly the octopus - provide a unique test case among invertebrates for examining the properties and conditions that afford a basal faculty of consciousness, and identifies future research directions for the study of consciousness in these tantalizing animals.
Invertebrate models of behavioural plasticity and human disease
In invertebrate preparations have provided a means to link neural mechanisms to behavioural plasticity and thus key insight into fundamental aspects of control systems, learning, and memory is captured.
A standardized battery of tests to measure Octopus vulgaris’ behavioural performance
A series of behavioural tasks to assess inter-individual variability in behaviours exhibited by the cephalopod mollusc Octopus vulgaris is introduced to provide a reliable tool to exploit this animal species for research in different fields.
Cephalopod Biology: At the Intersection Between Genomic and Organismal Novelties.
This review addresses the recent progress and impact of genomic and other molecular resources on research in cephalopods and outlines several key directions in which significant progress is expected and its impact on the understanding of the genetic background behind cEPhalopod biology and beyond.
Oxytocin mediated behavior in invertebrates: An evolutionary perspective
Studying oxytocin in invertebrates offers precise insights into the activity of neuropeptides on well‐defined neural circuits; the principles that emerge may also be represented in the more complex vertebrate brain.
The Gastric Ganglion of Octopus vulgaris: Preliminary Characterization of Gene- and Putative Neurochemical-Complexity, and the Effect of Aggregata octopiana Digestive Tract Infection on Gene Expression
The neurochemical complexity of the gastric ganglion in Octopus vulgaris is investigated and whether the expression of a selected number of genes was influenced by the magnitude of digestive tract parasitic infection by Aggregata octopiana is tested.
The Current State of Cephalopod Science and Perspectives on the Most Critical Challenges Ahead From Three Early-Career Researchers
This review and prospectus is also intended to suggest some concrete near-term goals to cephalopod researchers and inspire those working outside the field to consider the revelatory potential of these remarkable creatures.
The Use of a Species-Specific Health and Welfare Assessment Tool for the Giant Pacific Octopus, Enteroctopus dofleini
Results showed an irreversible upward trend in scores for feeding behavior and response to stimulus beginning 4 weeks prior to death, which suggests that upward trends in these two variables predict death within 3–4 weeks.
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.


Cognition and Recognition in the Cephalopod Mollusc Octopus vulgaris: Coordinating Interaction with Environment and Conspecifics
The examination of data and observations available provide the basis for asking new stimulating questions about the cognitive abilities of octopuses and their allies and open novel scenarios for future comparative research.
Cephalopod neurobiology: an introduction for biologists working in other model systems
This paper concisely summarizes major aspects of cephalopod biology, behavior, and ecology providing a backdrop against which neurobiology of these animals can be interpreted. Reproduction,
The Octopus: A Model for a Comparative Analysis of the Evolution of Learning and Memory Mechanisms
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.
The Evolution of Flexible Behavioral Repertoires in Cephalopod Molluscs
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.
A new perspective on the organization of an invertebrate brain.
How the octopus embodiment may be considered a 'key' to the development of its neural organisation and cognitive abilities is discussed.
Synaptic plasticity in cephalopods; more than just learning and memory?
It is concluded that cephalopods utilise short-, medium-, and long-term plasticity mechanisms that are superficially similar to those so far described in vertebrate and insect synapses.
