Cellular mechanisms underlying learning and memory were investigated in the octopus using a brain slice preparation of the vertical lobe, an area of the octopus brain involved in learning and memory. Field potential recordings revealed long-term potentiation (LTP) of glutamatergic synaptic field potentials similar to that in vertebrates. These findings suggest that convergent evolution has led to the selection of similar activity-dependent synaptic processes that mediate complex forms of…

Neurotransmission and neuromodulation systems in the learning and memory network of Octopus vulgaris

TLDR
A comprehensive histolabeling study to better characterize the neural elements in the vertical lobe of the octopus brain and confirms glutamatergic SFLs and cholinergic AMs and reveals more heterogeneity of the VL neurons than previously thought.

Functional and comparative assessments of the octopus learning and memory system.

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.

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 gyri of the octopus vertical lobe have distinct neurochemical identities

TLDR
The findings establish that the constituent lobes of the octopus superior frontal–vertical system have an intricate internal anatomy, one likely to reflect the presence of functional subsystems within cephalopod learning circuitry.

Multiple Forms of Long-Term Potentiation and Long-Term Depression Converge on a Single Interneuron in the Leech CNS

TLDR
LTP was observed in two types of synapses that converge on the same postsynaptic neuron in the leech CNS, and leech neurons exhibit synaptic plasticity with properties similar to LTP and LTD found in the vertebrate nervous system.

Mediation of classical conditioning in Aplysia californica by long-term potentiation of sensorimotor synapses.

TLDR
A cellular analog of classical conditioning in Aplysia was used to determine whether this form of invertebrate learning involves N-methyl-D-aspartate (NMDA)-type LTP, and NMDA receptor-antagonist dl-2-amino-5-phosphonovalerate significantly disrupted synaptic enhancement after associative training but did not disrupt synaptic Enhancement after nonassociative training.

Synaptic plasticity and memory: an evaluation of the hypothesis.

TLDR
It is concluded that a wealth of data support the notion that synaptic plasticity is necessary for learning and memory, but that little data currently supports the notion of sufficiency.

TLDR
It is demonstrated that Aplysia sensorimotor synapses are capable of hebbian LTP-similar to that exhibited by synapses in the mammalian hippocampus - and a role for this type of synaptic plasticity in classical conditioning of the defensive withdrawal reflex of AplySia is suggested.

Lesions of the vertical lobe impair visual discrimination learning by observation in Octopus vulgaris

Comparison of two forms of long-term potentiation in single hippocampal neurons.

TLDR
Although the induction of associational-commissural LTP requires in the postsynaptic cell N-methyl-D-aspartate (NMDA) receptor activation, membrane depolarization, and a rise in calcium, mossy fiber LTP does not.

Two components of long-term potentiation induced by different patterns of afferent activation

TLDR
It is reported that a component of LTP not requiring the activation of NMDA receptors can be induced in area CA1, and is suppressed by an antagonist of voltage-dependent Ca2+ channels.

Long-term potentiation--a decade of progress?

TLDR
A simple model is described that unifies much of the data that previously were viewed as contradictory about the molecular mechanisms of this long-lasting increase in synaptic strength in the hippocampus.

Novel form of long-term potentiation produced by a K+channel blocker in the hippocampus

TLDR
The results suggest that this new form of LTP is induced by a transient enhanced release of glutamate which generates a depolarization by way of the non-NMD A receptors and the consequent activation of voltage -dependent Ca2+ channels.

Changes in functional glutamate receptors on a postsynaptic neuron accompany formation and maturation of an identified synapse.

TLDR
The results indicate that changes in expression and distribution of functional receptors on L7 accompany the formation and maturation of SN synapses, consistent with the idea that the expression and sequential clustering of NMDA- and AMPA-type receptors may be essential for the formation of central synapses.
