“…relational mapping of the environment such that they can navigate to goal areas from different starting positions) but can learn in situations where the goal is indicated by a specific cue. Observations of increased nucleolar activity indicative of heightened protein synthesis and neuronal activity in Dl of fish involved in learning a spatial constancy but not a cue-guided task [Broglio et al, , 2011 are consistent with Dl involvement in the spatial aspects of learning.…”

“…Additional studies, using either a two-way shuttle avoidance or classical motor conditioning, demonstrate that fish with bilateral Dl ablations can learn if the UCS or shock directly follows the termination of the CS or warning signal (delay or non-trace avoidance) but not when a delay is inserted between the stimuli (trace avoidance condition) [Broglio et al, , 2011. The results indicate that Dl is involved in the temporal processing aspects of learning in goldfish.…”

“…In many of the experiments carried out by Salas and his colleagues (see Dl above), Dm lesions did not affect performance in spatial learning, reversal learning, or motor classical conditioning tasks, but the procedures did impair acquisition and retention in both delay and trace avoidance learning and the classical conditioning of heart rate slowing (bradycardia) following an electrical shock [Broglio et al, 2011]. The authors suggest that Dm mediates a 'fear-like' state related to the negative reinforcement in these forms of conditioning.…”

“…Salas and his colleagues used several experimental paradigms to study the effects of bilateral Dl lesions on learning in goldfish [Broglio et al, , 2011Durán et al, 2010]. Their results indicate that fish with bilateral Dl ablations (the figures suggest that Dlv was damaged more extensively than Dld) are unable to perform tasks requiring spatial constancy (i.e.…”

“…The pallium, rather than other brain areas, is emphasized in this review for several reasons: (1) there is convincing evidence that the dorsolateral (Dl) and dorsomedial (Dm) regions of the teleost pallium are homologous to the tetrapod hippocampus and pallial amygdala respectively [Braford, 1995[Braford, , 2009Northcutt, 2006Northcutt, , 2008Northcutt, , 2011Mueller and Wullimann, 2009;Maximino et al, 2013], and that the homologous areas control similar aspects of cognition and emotion in both groups [Broglio et al, 2011]; (2) the two pallial areas and a related dorsocentral (Dc) region attain their greatest relative development in fishes with the most complex behaviors (see examples of large palliums in fig. 1 d, f-h) [Schroeder, 1980;Ridet and Bauchot, 1990;Demski and Beaver, 2001;Bshary et al, 2002;Demski, 2003;Bshary, 2011], and (3) Dl and Dm vary in their development in closely related species living in different physical and/or social environments [Shumway, 2008[Shumway, , 2010Park and Bell, 2010;Costa et al, 2011].…”

Three interrelated pallial areas mediate behaviors reflective of the cognitive and emotional aspects of the teleost mind. The dorsocentral area (Dc) has specific associations with both of the other pallial areas and projects to major lower sensorimotor centers. While Dc generally functions as an output or modulatory component of the pallium, it probably also has integrative features important for certain behaviors. The dorsolateral region (Dl) has dorsal (Dld) and ventral (Dlv) divisions. In association with the dorsal part of Dc, Dld processes visual information via a ‘tectal loop' which is hypertrophied in certain coral reef species. The region also receives afferents related to other modalities. Functionally, Dld resembles the tetrapod sensory neocortex. Anatomical and behavioral data (i.e. involvement in spatial and temporal learning) strongly suggest that Dlv is homologous to the tetrapod hippocampus. The dorsal part of the dorsomedial area (Dmd) processes acoustic, lateral line, gustatory, and multimodal information. It has reciprocal connections with Dld such that the Dmd and Dld together can be considered the teleost nonolfactory ‘sensory pallium'. Behavioral studies indicate that Dmd creates the ‘fear' necessary for defense/escape and avoidance behaviors and controls several components of species-typical sexual and aggressive behavior (responsiveness, behavioral sequencing, and aspects of social cognition). While the functional results generally support the anatomical evidence that Dmd is homologous to the tetrapod amygdala, a case can also be made that Dmd has ‘sensory neocortex-like' features. Understanding the interrelationships of Dl, Dmd, and Dc seems a necessary ‘next step' in the identification of the neural processes responsible for mental experiences such as those of a unified sensory experience (Umwelt) or of feelings of discomfort versus well- being.

The gross morphology of the brain of Rineloricaria heteroptera and its relation to the sensory/behavioural ecology of the species is described and discussed. The sexual and ontogenetic intraspecific variation in the whole brain length and mass, as well as within/between the eight different brain subdivisions volumes, is also examined and discussed. Negative allometry for the whole brain length/mass and relative growth of the telencephalon and optic tecta was observed. Positive allometry was observed for the relative growth of the olfactory bulbs and medulla oblongata. Univariate and multivariate statistical analyses did not reveal significant differences in the brain subdivision growth rates among sexes and/or developmental stages, except for the optic tectum and some portions of the medulla oblongata, with juveniles and males showing more developed optic tecta and medullary subdivisions, respectively. The growth rates for each brain subdivision were relatively constant, and the slopes of the growth equations were almost parallel, except for those of the olfactory bulbs and medulla oblongata subdivisions, suggesting some degree of tachyauxesis of subdivisions against the entire brain. The corpus cerebelli was the more voluminous brain subdivision in most specimens (principally adults), followed by the optic tectum (the more voluminous subdivision in juveniles), hypothalamus, and telencephalon, in that order. Differences in the number of lamellae and relative size of the olfactory organ were also detected among developmental stages, which were more numerous and larger in adults. Based on these results, it is possible to infer an ontogenetic shift in the habitat/resource use and behaviour of R. heteroptera. Vision, primarily routed through the optic tectum, could be fundamental in early stages, whereas in adults, olfaction and taste, primarily routed through the olfactory bulbs and medulla oblongata, play more important roles.

Brain areas activated during visual learning in the cichlid fish Pseudotropheus zebra

The neural correlates of most cognitive functions in fish are unknown. This project aimed to identify brain regions involved in visual learning in the cichlid fish Pseudotropheus zebra. The expression of the protein pS6 was measured in 19 brain areas and compared between groups of individuals subjected to four different behavioral contexts (control, avoidance, trained, and novelty groups). Control group individuals were sacrificed with minimal interactions. Fish in the avoidance group were chased with a net for an hour, after which they were sacrificed. Individuals in the trained group received daily training sessions to associate a visual object with a food reward. They were sacrificed the day they reached learning criterion. Fish in the novelty group were habituated to one set of visual stimuli, then faced a change in stimulus type (novelty stimulus) before they were sacrificed. Fish in the three treatment groups showed the largest activation of pS6 in the inferior lobes and the tectum opticum compared to the control group. The avoidance group showed additional activation in the preoptic area, several telencephalic regions, the torus semicircularis, and the reticular formation. The trained group that received a food reward, showed additional activation of the torus lateralis, a tertiary gustatory center. The only area that showed strong activation in all three treatment groups was the nucleus diffusus situated within the inferior lobe. The inferior lobe receives prominent visual input from the tectum via the nucleus glomerulosus but so far, nothing is known about the functional details of this pathway. Our study showed for the first time that the inferior lobes play an important role in visual learning and object recognition.
