Does nocturnality drive binocular vision? Octodontine rodents as a case study.

Autor: Tomas Vega-Zuniga, Felipe S Medina, Felipe Fredes, Claudio Zuniga, Daniel Severín, Adrián G Palacios, Harvey J Karten, Jorge Mpodozis

Publikováno v: PLoS ONE, Vol 8, Iss 12, p e84199 (2013)

Binocular vision is a visual property that allows fine discrimination of in-depth distance (stereopsis), as well as enhanced light and contrast sensitivity. In mammals enhanced binocular vision is structurally associated with a large degree of fronta

An investigation into the cognition behind spontaneous string pulling in New Caledonian crows.

Autor: Alex H Taylor, Felipe S Medina, Jennifer C Holzhaider, Lindsay J Hearne, Gavin R Hunt, Russell D Gray

Publikováno v: PLoS ONE, Vol 5, Iss 2, p e9345 (2010)

The ability of some bird species to pull up meat hung on a string is a famous example of spontaneous animal problem solving. The "insight" hypothesis claims that this complex behaviour is based on cognitive abilities such as mental scenario building

Integrating multivariate and geostatistical analyses for assessing the socio-environmental vulnerability of children in the vicinity of a contaminated site

Autor: Felipe S. Medina, Soledad Burgos, Ana Karina Maldonado, Verónica Iglesias, Miguel A. Madrid

Publikováno v: International Journal of Environmental Health Research. 28:642-652

Vulnerability assessments are commonly based on complex indices that may be inappropriate for characterizing risks in small groups of people exposed to environmental hazards. The aim was to present a multivariate and geostatistical approach to explor

To what extent can the mammalian visual system be shaped by visual behavior? Here we analyze the shape of the visual fields, the densities and distribution of cells in the retinal ganglion-cell layer and the organization of the visual projections in

New Caledonian crows’ responses to mirrors

Autor: Russell D. Gray, Alex H. Taylor, Felipe S. Medina, Gavin R. Hunt

Publikováno v: Animal Behaviour. 82:981-993

Recent mirror studies with two corvid species have reported contrasting findings. Jungle crows, Corvus macrorhynchos, showed no self-contingent behaviour when confronted with mirrors, whereas Eurasian magpies, Pica pica, reportedly passed the ‘mark

Perineuronal satellite neuroglia in the telencephalon of New Caledonian crows and other Passeriformes: evidence of satellite glial cells in the central nervous system of healthy birds?

Autor: Gavin R. Hunt, M. Fabiana Kubke, J. Martin Wild, Russell D. Gray, Felipe S. Medina

Publikováno v: PeerJ
PeerJ, Vol 1, p e110 (2013)

Glia have been implicated in a variety of functions in the central nervous system, including the control of the neuronal extracellular space, synaptic plasticity and transmission, development and adult neurogenesis. Perineuronal glia forming groups a

Do new caledonian crows solve physical problems through causal reasoning?

Autor: Gavin R. Hunt, Felipe S. Medina, Alex H. Taylor, Russell D. Gray

Publikováno v: Proceedings. Biological sciences. 276(1655)

The extent to which animals other than humans can reason about physical problems is contentious. The benchmark test for this ability has been the trap-tube task. We presented New Caledonian crows with a series of two-trap versions of this problem. Th
