“…3B). Interestingly, the involvement of the lateral pallium of goldfish in spatial cognition seems to be selective to place learning, as damage to this area does not impair cue learning or other egocentric strategies [Salas et al, 1996a, b;Ló pez et al, 2000a;Rodríguez et al, 2002b]. In summary, these results demonstrate a striking functional similarity between the hippocampal pallium of amniotes and the lateral pallium of the telencephalon of the teleost fish.…”

“…3C-D). In fact, the place memory deficit observed after lateral pallium lesions in goldfish is as severe as that produced by the complete ablation of both telencephalic hemispheres [Salas et al, 1996a, b;Ló pez et al, 2000a;Rodríguez et al, 2002a, b]. In contrast, medial or dorsal pallium lesions do not produce any observable impairment in place learning [Rodrí-guez et al, 2002b] (fig.…”

Evolution of Forebrain and Spatial Cognition in Vertebrates: Conservation across Diversity

Historically the dominant trend in comparative brain and behavior research has emphasized the differences in cognition and its neural basis among species. In fact, the vertebrate forebrain shows a remarkable range of diversity and specialized adaptations. Probably the major morphological variation is that observed in the telencephalon of the actinopterygian fish, which undergoes a process of eversion during embryonic development, relative to the telencephalon of non-actinopterygians (for instance, amniotes), which develops by a process of evagination. These different developmental processes produce notable variation, mainly two solid telencephalic hemispheres separated by a unique ventricle in the actinopterygian radiation that contrasts with the hemispheres with internal ventricles in other groups. However, an increasing amount of evidence reveals that the forebrain of vertebrates, whether everted or evaginated, presents a common pattern of basic organization that supports highly conserved cognitive functions. We analyze here recent data indicating a close functional similarity between spatial cognition mechanisms in different groups of vertebrates, mammals, birds, reptiles, and teleost fish, and we show in addition that they rely on homologous neural mechanisms. Thus, 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.

“…Studies by Van Staaden et al [1995] and Huber et al [1997] also found larger telencephalons in cichlid species living in more spatially complex habitats created by shallow rock and vegetation compared to those species living in mid-water. A number of studies have provided evidence for the telencephalon's involvement in various complicated behaviours such as spatial learning [Salas et al, 1996a, b;López et al, 2000], avoidance responses [Portavella et al, 2003[Portavella et al, , 2004, territoriality, shoaling [Shinozuka and Watanabe, 2004;Martín et al, 2011] and reproductive behaviours such as mating strategy, courtship, nest building and parental care [Overmeir and Gross, 1974;Koyama et al, 1984;Pollen et al, 2007;Broglio et al, 2011].…”

Microhabitat Use Affects Brain Size and Structure in Intertidal Gobies

The ecological cognition hypothesis poses that the brains and behaviours of individuals are largely shaped by the environments in which they live and the associated challenges they must overcome during their lives. Here we examine the effect of environmental complexity on relative brain size in 4 species of intertidal gobies from differing habitats. Two species were rock pool specialists that lived on spatially complex rocky shores, while the remainder lived on dynamic, but structurally simple, sandy shores. We found that rock pool-dwelling species had relatively larger brains and telencephalons in particular, while sand-dwelling species had a larger optic tectum and hypothalamus. In general, it appears that various fish species trade off neural investment in specific brain lobes depending on the environment in which they live. Our previous research suggests that rock pool species have greater spatial learning abilities, enabling them to navigate their spatially complex environment, which may account for their enlarged telencephalon, while sand-dwelling species likely have a reduced need for spatial learning, due to their spatially simple habitat, and a greater need for visual acuity. The dorsal medulla and cerebellum size was unaffected by the habitat in which the fish lived, but there were differences between species indicative of species-specific trade-offs in neural investment.

“…These early findings confirm the role of the telencephalon in spatial behavior of fish, but they also relate to the general debate about the existence of successive reversal learning in fish. Overmier and Hollis (1990) reported that fish without brain lesions "[did not] improve when they were repeatedly required to reverse successfully the previous trained response" (p. 217), and the telencephalon ablated fish were different only in the fact that, compared to the "normal" fish which did not reduce errors across reversals, they actually showed lower performance across successive reversals, Interestingly, the subsequent findings of López, Bingman, Rodríguez, Gómez, and Salas (2000) seem to contradict the conclusions of Overmier and Hollis (1990). Lopez et al found that goldfish with bilateral telencephalic ablation, sham operated or intact, were successfully trained in a spatial constancy task or in a directly cued task.…”

a b s t r a C tTwo predominant approaches for studying the neurobiology of learning in fish are reviewed: brain lesions and chemical stimulation. Habituation, sensitization, Pavlovian Conditioning, spatial behavior, and emotional learning are the specific processes analyzed. Regarding the effect of brain lesions, telencephalic ablations produced impairment of habituation learning; conversely, cerebellum lesions caused deficiencies in classical conditioning of eye-retraction and spatial learning (similar effects observed in mammals suggest that the functions of the cerebellum may have evolved early in vertebrate history). Medium Pallium (MP) areas have been identified as critical for emotional learning in fish. Furthermore, neurobehavioral functions of MP seem to be similar to the functions of the amygdala in mammals. Relating to neurochemical processes, NMDA receptor antagonists affected the acquisition of avoidance and fear conditioning in a dose-dependent manner. Alternatively, Nitric Oxide (NO) and cyclic Guanosine Monophosphate (cGMP) seem to be involved in the consolidation process of emotional learning. Keywords authorNeurobehavioral functions, neurochemical functioning, teleost fish, learning processes, spatial learning, Medium Lateral Pallium. Keywords plusTeleost Fish, Neurochemistry, Cerebrum, Injuries. r e s u m e n Se revisaron dos aproximaciones al estudio de la neurobiología del aprendizaje en peces teleósteos: lesiones cerebrales y estimulación química. Respecto al efecto de lesiones cerebrales, la literatura reporta que las ablaciones del telencéfalo producen deficiencias en habituación, mientras que las lesiones en el cerebelo afectan el condicionamiento clásico de retracción ocular y aprendizaje espacial (efectos similares observados en mamíferos sugieren que las funciones del cerebelo pudieron haber evolucionado tempranamente en la historia de los vertebrados). Áreas del Medium Pallium (MP) parecen ser vitales en el aprendizaje emocional de los peces; más aún, las funciones del MP aparentan ser similares a las de la amígdala en mamíferos. Con respecto a procesos neuroquímicos, los antagonistas de los receptores NMDA, mostraron afectar la adquisición de condicionamiento de evitación y miedo. Por último, el óxido nítrico y el guanosín monofosfato cíclico han sido relacionados con los procesos de consolidación del aprendizaje emocional.
