...Brooke J. Vetter; Jonathan T. Perelmuter; Nicholas R. Lozier; Joseph A. Sisneros; Paul M. Forlano Introduction: The plainfin midshipman fish (Porichthys notatus) relies on the production and reception of social acoustic signals for reproductive success. During spawning, male midshipman fish produce...

.... In particular, the idea that fish cannot experience psychological stress is still prevalent, partly due to the lack of a homologous brain area to the neocortex. However, emerging evidence suggests that teleosts can undergo psychological stress, defined as a subjective and perceptual experience of the stressor...

...Ke Jiang; Ke Wei; Shi Xi Chen; Jing Huang Mudskippers are intertidal burrowing fish with unique living habits. So far, studies on the cytoarchitecture of the brain in fish with such behaviors remain limited. Therefore, documenting the neuroanatomy of this animal is of interest because of its unique...

... various other errors made frequently when comparing brain morphology between animals. Finally, the VRT is applied to investigate sex differences in the swordtail fish (Xiphophorus hellerii) , which show profound differences in the size of the valvula cerebelli. [email protected] 13 08 2019...

.... Specifically, compared to control fish, fish exposed to a simulated predator environment tended to be less aggressive, more exploratory, and more neophobic; and fish raised in both complex and variable social environments tended to be less neophobic. Exposure to a simulated predator environment tended to lower...

...Robert A. Mohr; Yiran Chang; Ashwin A. Bhandiwad; Paul M. Forlano; Joseph A. Sisneros While the peripheral auditory system of fish has been well studied, less is known about how the fish’s brain and central auditory system process complex social acoustic signals. The plainfin midshipman fish...

.... The intrinsic physiological polarization of sensory hair cells on the otolith organs confers sensitivity to the direction of stimulation, including the direction of particle motion at auditory frequencies. In extant fishes, afferents from otolithic end organs encode the axis of particle motion, which...

...Kent D. Dunlap Fish have unusually high rates of brain cell proliferation and neurogenesis during adulthood, and the rates of these processes are greatly influenced by the environment. This high level of cell proliferation and its responsiveness to environmental change indicate that such plasticity...

...Nicholas B. Edmunds; Kevin S. McCann; Frédéric Laberge Previous work showed that teleost fish brain size correlates with the flexible exploitation of habitats and predation abilities in an aquatic food web. Since it is unclear how regional brain changes contribute to these relationships, we...

... families, the development of the epithalamus was examined in the medaka fish (Oryzias latipes). For this purpose, a green fluorescent protein-transgenic medaka line, in which the pineal complex (pineal and parapineal) is visible fluorescently, was used. We found that a distinct parapineal was present...

... 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...

... of a unified sensory experience (Umwelt) or of feelings of discomfort versus well- being. The goal of this paper is to identify pallial substrates of mental activity and their behavioral correlates in the advanced bony fishes or teleosts (ca. 30,000 species) [Nelson, 2006]. To this end, neurobehavioral...

...John C. Wathey Although much is known about the optics and mechanism of ocular accommodation in teleost fishes, there is to date no description of the neurons innervating the muscle of accommodation, the lens retractor. I have identified accommodation motor neurons in the kelp bass, Paralabrax...

... was found in motoneurons and in ventrolaterally located cells only in Neoceratodus . Fiber labeling showed a predominance of CR-containing axons in the lateral and ventral funiculi of presumed supraspinal origin. These results show that lung-fishes and tetrapods have many features in common, suggesting...

...Craig W. Hawryshyn Teleost fishes are capable of detecting and behaviorally responding to linearly polarized light. Fish exhibit free-swimming spatial orientation to imposed and natural polarized light fields, and the fidelity of this spatial orientation depends heavily on UV and short wavelength...
