Spatial cognition and its neural basis in teleost fishes
TLDR
Results that suggest a striking similarity in some cognitive processes and their neural basis between fish and land vertebrates are consistent with the possibility that these vertebrate groups share a common basic pattern of brain and behaviour organisation inherited from a common ancestor and conserved through a long history of separate evolution.
Evolution of the hippocampus in reptiles and birds

    The Journal of comparative neurology
  • 2016
TLDR
It seems likely that some similarities in the function of the hippocampus between birds and mammals, notably its role in the ability to remember many different locations without extensive training, likewise evolved convergently, and the hypothesis itself suggests some promising new research directions.
Evolution of Forebrain and Spatial Cognition in Vertebrates: Conservation across Diversity
TLDR
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.
Neuropsychology of learning and memory in teleost fish.
TLDR
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.
Olfaction, navigation, and the origin of isocortex
TLDR
This article proposes that the origin of the isocortex was driven by behavioral adaptations involving olfactory driven goal-directed and navigating behaviors, linked with increasing sensory development, which provided selective pressure for the expansion of the dorsal pallium.
Avian brains and a new understanding of vertebrate brain evolution
TLDR
The traditional view of telencephalic evolution is summarized before reviewing more recent findings and insights, and the new nomenclature that has been developed by the Avian Brain Nomenclatures Forum is presented, and its implications for the understanding of vertebrate brain evolution and its associated homologies are discussed.
Contribution of Genoarchitecture to Understanding Hippocampal Evolution and Development
The hippocampal formation is a highly conserved structure of the medial pallium that works in association with the entorhinal cortex, playing a key role in memory formation and spatial navigation.…
Hallmarks of a common forebrain vertebrate plan: Specialized pallial areas for spatial, temporal and emotional memory in actinopterygian fish
Teleostean and mammalian forebrains contrasted: Evidence from genes to behavior
TLDR
The major focus of this Review is to discuss related data in teleosts, mostly by explicitly comparing mouse and zebrafish forebrains.
The evolutionary origin of the mammalian isocortex: Towards an integrated developmental and functional approach
TLDR
The isocortex may have originated partly as a consequence of an overall “dorsalizing” effect during pallial development, which was driven by selective pressures favoring the development of associative networks between the dorsal cortex, the olfactory cortex, and the hippocampus, which participated in spatial or episodic memory in the early mammals.

The importance of comparative studies and ecological validity for understanding hippocampal structure and cognitive function
TLDR
It is argued that traditional laboratory studies likely do not reveal the richness and complexity of hippocampal function, and suggested that, from an evolutionary perspective, the primary function of the hippocampal formation is a role in some aspect of spatial cognition.

TLDR
Caveats are raised concerning the above interpretations of DM and DL, which may have evolved independently of the telencephalic zones in tetrapods and may thus represent examples of homoplasy.

The forebrain of gnathostomes: in search of a morphotype.
TLDR
A morphotype of the forebrain of gnathostomes was generated by using out-group analysis to identify the shared primitive characters present in the forebrains of extant gnathOSTomes, and hypotheses of phylogenetic relationships profoundly affect the resulting morphotype.

Evolution of the telencephalon in nonmammals.
TLDR
The relatively sophisticated armamentarium of neurobiological tech­ niques available today allows us to establish more accurately the anatomy of the telencephalon; these data, data from the fossil record, and a more sophisticated view of vertebrate phylogeny allow us to propose and test new hypotheses regarding the evolution of the vertebrate telencesphalon.
Evolution of the Vertebrate Central Nervous System: Patterns and Processes
TLDR
Analysis of a number of CNS characters that are usually assumed to be homologous reveals that homoplasous characters appear among them, and definitions of homology and homoplasy are reviewed, as are the concepts that bear on their application.
Dissociation of place and cue learning by telencephalic ablation in goldfish.
TLDR
The results offer additional evidence that place and cue learning in fish are subserved by different neural substrates and that the telencephalon of the teleost fish, or some unspecified structure within it, is important for spatial learning and memory in a manner similar to the hippocampus of mammals and birds.
Impaired place learning and unimpaired cue learning in hippocampal-lesioned pigeons.
TLDR
The results support the notion that avian and mammalian hippocampal functions are quite similar, in terms of the tasks for which their processing is crucial and the roles for which it is not.
