Espinoza, Sergio; Pinto Hamuy, Teresa; Passig, Claudia; Carreño, Fernando; Marchant, Fernando; Urzúa Salinas, Cristhian (Elsevier, 1999)The Morris water-maze task was used to evaluate the role of the anteromedial extrastriate visual cortex in the processing of visuospatial information in rats. Six gray male rats received bilateral ibotenic acid injections ...

Cogan-Schilkrut, Rebeca; Pinto Hamuy, Teresa; Saavedra, Maria A. (1970)The learning, retention and relearning of an instrumental visual avoidance response was studied in 98 rats, including normal rats and those with frontal, somatic, visual and auditory ablations. Significant differences were ...

Pinto Hamuy, Teresa; Montero, Vicente M.; Torrealba, Fernando (2004)The primary visual cortex of rats is surrounded laterally (in Oc2L) and medially (in Oc2M) by several peristriate visual areas. Previous studies from our laboratory demonstrated that bilateral lesions in Oc2L result in ...

Espina Marchant, Pablo; Pinto Hamuy, Teresa; Bustamante, Diego; Morales, Paola; Herrera-Marschitz Muller, Mario (2009)Rats use place (allocentric) or stimulus-response (egocentric) learning strategies for foraging under ethological and/or experimental conditions, proposed to be conveyed by hippocampus or neostriatum, respectively. We ...

Pinto Hamuy, Teresa; Olavarria, Jaime; Guic-Robles, Eliana; Morgues, Monica; Nassal, Omar; Petit, Daniel (1987)The involvement of rat anteromedial extrastriate cortex (area AM, in the anterior portion of area 18b) in the integration of visual and somatic cues was assessed behaviorally. Following restricted bilateral lesions of ...
-
Moneta, María Eugenia; Lolas Stepke, Fernando; Pinto Hamuy, Teresa (1974)The influence of response-dependent variables on Slow Cortical Potential (SCP) morphology was studied, in order to corroborate motor cortex contribution to SCP genesis. Electrical responses were recorded using non-polarizable ...

Pinto Hamuy, Teresa; Bracchitta, Humberto; Lagarrigue, Isabel (1969)The evolution of DC cortical shifts during learning, as well as its association with behavioral responses, were studied in thirteen rabbits using unpolarizable electrodes chronically implanted. The animals were trained to ...

Bracchitta, Humberto; Lolas Stepke, Fernando; Pinto Hamuy, Teresa (1973)Data concerning the evolution of SCP in the rabbit cortex during learning are presented. Unpolarizable electrodes were implanted in nine Ss at different sites of motor and somato-sensory cortex. These animals were trained ...

Espina Marchant, Pablo; Pinto Hamuy, Teresa; Bustamante, Diego; Morales, Paola; Robles, Luis; Herrera-Marschitz Muller, Mario (Society of Biology of Chile, 2006)Place memory is relevant for exploration and forage behaviour. When food supply is dispersed, a win-shift has advantage over a win-stay strategy. In the Olton Octagonal Maze, the rat follows a win-shift strategy using ...

Lolas Stepke, Fernando; Araya Araya, Fernando; De Andraca,; Pinto Hamuy, Teresa (1976)Vertex slow potentials during the foreperiod of a classical reaction time task are shown to be influenced by modality of warning stimulus (auditory vs visual) and Ss variables. A directional anticipatory specificity-defined ...
