Neuronal mechanisms of learning in teleost fish
Two predominant approaches for studying the neurobiology of learning in fish are reviewed: brain lesions and chemical stimulation and neurobehavioral functions of medium Pallium areas seem to be similar to the functions of the amygdala in mammals.
Neuropsychology of learning and memory in teleost fish.
The data reviewed here show a remarkable parallelism between mammals and teleost fish concerning the role of different brain centers in learning and memory and cognitive processes, and suggest that these separate memory systems could have appeared early during the evolution of vertebrates, having been conserved through phylogenesis.
Selective involvement of the goldfish lateral pallium in spatial memory
Regional synapse gain and loss accompany memory formation in larval zebrafish
The results suggest that memory formation due to classical conditioning is associated with reciprocal changes in synapse numbers in the pallium, and this change could account for the robust nature of memory formation from classical conditioning.
Cognitive and emotional functions of the teleost fish cerebellum


Avoidance Response in Goldfish: Emotional and Temporal Involvement of Medial and Lateral Telencephalic Pallium
These data support the presence of two different systems of memory in fish, based on discrete telencephalic areas: the MP, involved in an emotional memory system; and the LP,involved in a spatial, relational, or temporal memory system.
Conservation of Spatial Memory Function in the Pallial Forebrain of Reptiles and Ray-Finned Fishes
The results indicate that lesions to the MC of turtles and to the LP of goldfish, like hippocampal lesions in mammals and birds, selectively impair map-like memory representations of the environmental space and suggest that the presence of a hippocampus-dependent spatial memory system is a primitive feature of the vertebrate forebrain that has been conserved through evolution.

Analysis of the role of the cerebellum in basic delay conditioning (stimuli overlap) indicates that the memories are formed and stored in the Cerebellar long-term depression is considered as a putative mechanism of memory storage.
Differential Effects of Cerebellar, Amygdalar, and Hippocampal Lesions on Classical Eyeblink Conditioning in Rats
The results suggest that, even during a simple delay eyeblink conditioning, animals learn about different aspects associated with the behavioral task that are subserved by multiple brain-memory systems that interact to produce the overall behavior.

Spatial learning and memory deficits after telencephalic ablation in goldfish trained in place and turn maze procedures.
The results suggest that the fish telencephalon plays a crucial role in complex place learning, and that ablation exclusively impaired performance in animals using place strategies.
Evolution of Forebrain and Spatial Cognition in Vertebrates: Conservation across Diversity
Recent functional and behavioral comparative evidence is added to the developmental and neuroanatomical data suggesting that the evolution of cognitive capabilities and their neural basis in vertebrates could have been more conservative than previously realized.
