“…Although the majority of experiments reviewed above, in which tract section alone was performed, showed no difference between these and unoperated animals, the study of Frank et al (1972) did detect a difference. Further, Cain (1974) examined the results of damage to the mammalian olfactory bulb and concluded that the effects are far more extensive than a mere loss of smell.…”

“…In accordance with the existence of trade-offs between cognitive abilities, as proposed by Tellos-Ramos and colleagues (2019) , the ecology of the guppy might favour spatial memory rather than the advanced learning abilities investigated here. Second, cognitive processes involved in the ability to adopt an efficient learning strategy are controlled by a specific region in the telencephalon ( Frank et al, 1972 ; Izquierdo et al, 2016 ; López et al, 2000 ; Watanabe, 2012 ). Primates have among the largest relative telencephalon sizes in the animal kingdom ( Finlay and Darlington, 1995 ), and telencephalon neuron number and density in parrots and many songbirds are equivalent to those of primates ( Olkowitcz et al, 2016 ).…”

“…In this case A+ B− becomes A− B+. The switch in reward contingency is thought to be more cognitively demanding and involves different cognitive processes and brain regions from those for the initial discrimination task ( Frank et al, 1972 ; Izquierdo et al, 2016 ; López et al, 2000 ; Watanabe, 2012 ; Buechel et al, 2018 ). The initial discrimination tests for associative learning ability, while the ability to reverse and learn the new reward contingency tests behavioural flexibility ( Bitterman, 1965 ; Bond et al, 2007 ; Izquierdo et al, 2016 ; Shettleworth, 2010 ).…”

Reversal learning assays are commonly used across a wide range of taxa to investigate associative learning and behavioural flexibility. In serial reversal learning, the reward contingency in a binary discrimination is reversed multiple times. Performance during serial reversal learning varies greatly at the interspecific level, as some animals adopt a rule-based strategy that enables them to switch quickly between reward contingencies. A larger relative brain size, generating enhanced learning ability and increased behavioural flexibility, has been proposed to be an important factor underlying this variation. Here, we experimentally tested this hypothesis at the intraspecific level. We used guppies (Poecilia reticulata) artificially selected for small and large relative brain size, with matching differences in neuron number, in a serial reversal learning assay. We tested 96 individuals over 10 serial reversals and found that learning performance and memory were predicted by brain size, whereas differences in efficient learning strategies were not. We conclude that variation in brain size and neuron number is important for variation in learning performance and memory, but these differences are not great enough to cause the larger differences in efficient learning strategies observed at higher taxonomic levels.

“…Following Overmier and Hollis' (1990) review of Frank, Flood, and Overmier (1972) and Warren's (1961) experiments, the general conclusion is that telencephalic ablated fish performed poorly in a spatial, successive reversal task compared to both normal fish or subjects with their olfactory bulbs removed. 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.…”

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.
