Mayol Troncoso, Rocío Verónica (Universidad de Chile, 2018)El espectro Esquizofrenia es un trastorno mental severo y crónico que afecta alrededor de 0.7% de la población mundial y corresponde a una de las enfermedades mentales más invalidantes dado que se inicia en etapas precoces ...

Rivero Campos, Betel Valentina (Universidad de Chile, 2017)El aprendizaje motor por imitación diferida, ha sido poco estudiado, sobre todo en secuencias espaciales largas, que involucren movimientos corporales globales, y particularmente en adultos sanos. En la tarea propuesta, ...

Ruido vibrotáctil espacialmente coincidente mejora la detección de estímulos por debajo del umbral Arredondo Gamboa, Luis Togo (Universidad de Chile, 2022)La resonancia estocástica (SR) es un fenómeno presente en los sistemas de detección no lineal, en los que se ha demostrado que la adición de cierta cantidad de ruido óptimo mejora el rendimiento de detección de estímulos ...

Saccade-related modulations of neuronal excitability support synchrony of visually elicited spikes Ito, Junji; Maldonado Arbogast, Pedro; Singer, Wolf; Grün, Sonja (2011)During natural vision, primates perform frequent saccadic eye movements, allowing only a narrow time window for processing the visual information at each location. Individual neurons may contribute only with a few spikes ...

Délano, Paul H.; Pavez Arce, Elizabeth; Robles Wobbe, Luis; Maldonado Arbogast, Pedro (SPRINGER, 2008-08)Besides the intensity and frequency of an auditory stimulus, the length of time that precedes the stimulation is an important factor that determines the magnitude of early evoked neural responses in the auditory cortex. ...

Ossandón, José P.; Helo Herrera, Andrea; Montefusco Siegmund, Rodrigo; Maldonado Arbogast, Pedro (2010-03-31)Visual event-related potentials (ERPs) produced by a stimulus are thought to reflect either an increase of synchronized activity or a phase realignment of ongoing oscillatory activity, with both mechanisms sharing the ...

Ito, Junji; Yamane, Yukako; Suzuki, Mika; Maldonado Arbogast, Pedro; Fujita, Ichiro; Tamura, Hiroshi; Grn, Sonja (Nature Publishing Group, 2017)© 2017 The Author(s). Previous studies have reported that humans employ ambient and focal modes of visual exploration while they freely view natural scenes. These two modes have been characterized based on eye movement ...

Manzur, Hachi E.; Álvarez, Joel; Babul Ayub, María Cecilia; Maldonado Arbogast, Pedro (Oxford University Press, 2013)The temporal correlation hypothesis proposes that cortical neurons engage in synchronized activity, thus configuring a general mechanism to account for a range of cognitive processes from perceptual binding to consciousness. ...

Maldonado Arbogast, Pedro; Babul Ayub, María Cecilia; Singer, Wolf; Rodríguez Silva, Eugenio; Berger, Denise; Grün, Sonja (2008-09)When inspecting visual scenes, primates perform on average four saccadic eye movements per second, which implies that scene segmentation, feature binding, and identification of image components is accomplished in 200 ...

Morales Torres, Ricardo Ignacio (Universidad de Chile, 2019)Cuando nos enfrentamos a información visual ambigua nuestro sistema perceptual, mediante claves contextuales, busca llegar a la interpretación más adecuada. Si no existe información suficiente para que esto ocurra la ...

Berger, Denise; Pazienti, Antonio; Flores, Francisco J.; Nawrot, Martin P.; Maldonado Arbogast, Pedro; Grün, Sonja (Elsevier, 2012)Humans and other primates move their eyes several times per second to foveate at different locations of a visual scene. What features of a scene guide eye movements in natural vision? We recorded eye movements of three ...
