Comparative analysis of brain function in invertebrates with sophisticated behaviors, such as the octopus, may advance our understanding of the evolution of the neural processes that mediate complex behaviors. Until the last few years, this approach was infeasible due to the lack of neurophysiological tools for testing the neural circuits mediating learning and memory in the brains of octopus and other cephalopods. Now, for the first time, the adaptation of modern neurophysiological methods to… Expand

TLDR
Recent studies of the neurophysiological properties of the vertical lobe system in the cephalopod brain are reviewed, suggesting that a convergent evolutionary process has resulted in similar neural organization and activity-dependent long-term synaptic plasticity in all these learning and memory systems, even though the invertebrate systems conserve their typical anatomical and electrophysiological features. Expand
The vertical lobe of cephalopods: an attractive brain structure for understanding the evolution of advanced learning and memory systems
TLDR
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.

The Neurophysiological Basis of Learning and Memory in Advanced Invertebrates: The Octopus and the Cuttlefish
TLDR
This chapter summarizes recent neurophysiological research in the octopus and cuttlefish vertical lobe system that, for the first time, allows a functional and computational approach to the evolution of learning and memory systems. Expand
The Octopus Vertical Lobe Modulates Short-Term Learning Rate and Uses LTP to Acquire Long-Term Memory
TLDR
The results suggest that the learning and memory system in the octopus, as in mammals, is separated into short- and long-term memory sites, and the VL, which mediates long- term memory acquisition through LTP, also modulates the circuitry controlling behavior and short-term learning. Expand
A role for nautilus in studies of the evolution of brain and behavior
TLDR
Research on the behavior and sensory biology of Nautilus pompilius gives the first indications of learning and memory in this ancient genus and suggests that even with a far simpler brain containing no clearly defined ‘memory’ center, nautilus performs simple cognitive tasks comparably to its more derived relatives. Expand
A Brain Atlas of the Long Arm Octopus, Octopus minor
TLDR
This is the first brain atlas, not only for an Octopodiformes species but also among adult cephalopods, and it is anticipated that this atlas will provide a valuable resource for comparative neuroscience research. Expand
The autonomous arms of the octopus
TLDR
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. Expand
Behavioral Analysis of Learning and Memory in Cephalopods
Many aspects of cephalopods' learning and memory capabilities are still puzzling, despite the large number of studies carried out on the subject over the past century. For example, what doExpand
The cephalopod specialties: complex nervous system, learning, and cognition1
TLDR
Free of the molluscan shell and with evolutionary pressure from the bony fishes, coleoids have evolved a specialty in cognition and they may have a simple form of consciousness. Expand
Observational and Other Types of Learning in Octopus
TLDR
This chapter provides an update on the experimental evidence for observational learning in the octopus and discusses the constraints and peculiarities of social learning and the potential evolutionary meanings of this capability in this cephalopod mollusk. Expand

TLDR
Three relatively well studied cases are reviewed here: electric communication among gymnotiform and mormyriform fishes, prey capture among frogs, and sound localization among owls, which demonstrate that evolutionary convergence in brain anatomy and function is widespread. Expand
A learning and memory area in the octopus brain manifests a vertebrate-like long-term potentiation.

Special emphasis will be given to those features of the cephalopod nervous system that are unusual or even unique, often rivaling the equivalent parts of the vertebrate nervous system in sophistication; some of these features may characterize higher brain and nervous system function. Expand

Comparison of ongoing compound field potentials in the brains of invertebrates and vertebrates
TLDR
Compound field potential fluctuations of higher brain centers (the micro-EEG of some authors) are considered as a biological phenomenon, a sign of the activity in the organized assemblage of cells, and amplitude does not change greatly with small shifts in electrode position, as it does in invertebrates and lower vertebrates.

TLDR
A comparative analysis of gene expression in octopus and human camera eyes suggests that a larger number of conserved genes and their similar gene expression may be responsible for the convergent evolution of the camera eye. Expand
