Deichler, Alfonso; Carrasco, Denisse; López Jury, Luciana; Vega Zúñiga, Tomás; Márquez, Natalia; Mpodozis Marín, Jorge; Marín, Gonzalo J. (Nature Research, 2020)The parabigeminal nucleus (PBG) is the mammalian homologue to the isthmic complex of other vertebrates. Optogenetic stimulation of the PBG induces freezing and escape in mice, a result thought to be caused by a PBG projection ...

Marín Game, Gonzalo; Durán, Ernesto; Morales, Cristian; González-Cabrera, Cristian; Sentis, Elisa; Mpodozis Marín, Jorge; Letelier Parga, Juan (2012-01-18)When a salient object in the visual field captures attention, the neural representation of that object is enhanced at the expense of competing stimuli. How neural activity evoked by a salient stimulus evolves to take ...

Fredes, Felipe; Vega Zúñiga, Tomás; Karten, Harvey J.; Mpodozis Marín, Jorge (2012)The mammalian pulvinar complex is a collection of dorsal thalamic nuclei related to several visual and integrative processes. Previous studies have shown that the superficial layers of the superior colliculus project to ...

González Gómez, Paulina L.; Madrid López, Natalia; Salazar, Juan E.; Suárez, Rodrigo; Razeto Barry, Pablo; Mpodozis Marín, Jorge; Bozinovic, Francisco; Vásquez Salfate, Rodrigo (2014)In scatter-hoarding species, several behavioral and neuroanatomical adaptations allow them to store and retrieve thousands of food items per year. Nectarivorous animals face a similar scenario having to remember quality, ...

Vega Zúñiga, Tomás; Medina, Felipe S.; Fredes, Felipe; Zuniga, Claudio; Severín, Daniel; Palacios, Adrián G.; Karten, Harvey J.; Mpodozis Marín, Jorge (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 ...

Sobrero, Raúl; Fernández Aburto, Pedro; Ly-Prieto, Álvaro; Delgado, Scarlett E.; Mpodozis Marín, Jorge; Ebensperger, Luis A. (Karger, 2016)Navigational and social challenges due to habitat conditions and sociality are known to influence dentate gyrus (DG) morphology, yet the relative importance of these factors remains unclear. Thus, we studied three natural ...

Ramírez, Edgardo; Marín, Gonzalo; Mpodozis Marín, Jorge; Letelier, Juan Carlos (Springer Verlag, 2014)© 2014, The Author(s).There is a consensus that birds detect the earth’s magnetic field and use some of its features for orientation and homing purposes. Since the late 1960s, when the first solid behavioral evidence of ...

Mpodozis Marín, Jorge; Cox, Kevin; Shimizu, Toru; Bischof, Hans; Woodson, Walter; Karten, Harvey (1996)The avian nucleus rotundus, a nucleus that appears to be homologous to the inferior1 caudal pulvinar of mammals, is the major target of an ascending retino-tecto-thalamic pathway. Further clarification of the inputs to ...
-
Suárez, Rodrigo; Mpodozis Marín, Jorge (2009)The vomeronasal system (VNS) of rodents participates in the regulation of a variety of social and sexual behaviours related to semiochemical communication. All rodents studied so far possess two parallel pathways from the ...

Vega Zúñiga, Tomás; Mpodozis Marín, Jorge; Karten, Harvey J.; Marín, Gonzalo; Hain, Sarah; Luksch, Harald (Wiley-Liss Inc., 2014)The nucleus geniculatus lateralis pars ventralis (GLv) is a prominent retinal target in all amniotes. In birds, it is in receipt of a dense and topographically organized retinal projection. The GLv is also the target of ...

Faunes, Macarena; Botelho, João Francisco; Galleguillos, Patricio Ahumada; Mpodozis Marín, Jorge (Frontiers Research Foundation, 2015)© 2015 Faunes, Francisco Botelho, Ahumada Galleguillos and Mpodozis. Owen's pre-evolutionary definition of a homolog as "the same organ in different animals under every variety of form and function" and its redefinition ...

Suárez, Rodrigo; Santibáñez, Rodrigo; Parra, Daniela; Coppi, Antonio A.; Abrahão, Luciana M.B.; Sasahara, Tais H.C.; Mpodozis Marín, Jorge (2011)The vomeronasal system is crucial for social and sexual communication in mammals. Two populations of vomeronasal sensory neurons, each expressing Gαi2 or Gαo proteins, send projections to glomeruli of the rostral or caudal ...

Spatial organization of the pigeon tectorotundal pathway: An interdigitating topographic arrangement Marín, Gonzalo; Letelier, Juan Carlos; Henny, Pablo; Sentis, Elisa; Farfán, Gonzalo; Fredes, Felipe; Pohl, Nélida; Karten, Harvey J.; Mpodozis Marín, Jorge (2003)The retinotectofugal system is the main visual pathway projecting upon the telencephalon in birds and many other nonmammalian vertebrates. The ascending tectal projection arises exclusively from cells located in layer 13 ...

Vargas Milne, Alexander; Botelho, Joao F.; Mpodozis Marín, Jorge (Wiley, 2020)Living beings are autopoietic systems with highly context-dependent structural dynamics and interactions, that determine whether a disturbance in the genotype or environment will lead or not to phenotypic change. The ...

Karten, Harvey J.; Cox, Kevin; Mpodozis Marín, Jorge (1997)The tectofugal pathway is a massive ascending polysynaptic pathway from the tectum to the thalamus and then to the telencephalon. In birds, the initial component of this pathway is known as the tectorotundal pathway; in ...
