    • Effects of Electrical Stimulation of Olivocochlear Fibers in Cochlear Potentials in the Chinchilla 
      Elgueda, Diego; Délano, Paul H.; Robles Wobbe, Luis (SPRINGER, 2011-06)
      The mammalian cochlea has two types of sensory cells; inner hair cells, which receive auditory-nerve afferent innervation, and outer hair cells, innervated by efferent axons of the medial olivocochlear (MOC) system. The ...
    • Función vestibular cortical y de tronco encefálico en niños con trastorno de déficit atencional con ... 
      Isaac García, María Valeria (Universidad de Chile, 2017)
      Estudios recientes muestran que niños con trastorno de déficit atencional con hiperactividad (TDAH) presentan más dificultades en tareas de equilibrio estático y dinámico que niños de desarrollo normal. En la mayoría de ...
    • Hipoacusia como factor de riesgo para demencia 
      Wimmer del Solar, Jonathan; Delgado Derio, Carolina; Torrente Avendaño, Mariela; Délano, Paul H. (Sociedad Médica de Santiago, 2020)
      In the last decades, there has been an increase in life expectancy in the world, with the consequent modification in the proportion of adults over 60 years. This is accompanied by an increase in pathologies for which aging ...
    • Individual and sex distinctiveness in bark calls of domestic chinchillas elicited in a distress context 
      Moreno Gómez, Felipe; León, Alex; Velásquez, Nelson A.; Penna Varela, Mario; Délano, Paul H. (Acoustical Soc. Amer., 2015)
      Animals obtain information about their social environment by means of communication signals, which provide relevant subtle cues for individual recognition. An important requisite for this process is the existence of ...
    • A neutral cue facilitates detection of a visual target by modulating attention 
      Hamamé, Carlos M.; Délano, Paul H.; Robles Wobbe, Luis (SOC BIOLGIA CHILE, 2008)
      Twelve rats were trained to perform a two-choice visual detection task in which a right or left light was presented and the animals were required to press the lever located under the illuminated light for a food reward. ...
    • Relevance of a neutral cue in a two-choice detection task in the rat 
      Hamamé, Carlos M.; Délano, Paul H.; Robles Wobbe, Luis (2006)
      Relevance of a neutral cue for performance in a two-choice visuospatial detection task was examined. Nine rats were trained, 5 with short intertrial interval (ITI) and 4 with long ITI, to detect a target (lateral ...
    • Selective Attention to Visual Stimuli Reduces Cochlear Sensitivity in Chinchillas 
      Délano, Paul H.; Elgueda, Diego; Hamamé, Carlos M.; Robles Wobbe, Luis (SOC NEUROSCIENCE, 2007-04)
      It is generally accepted that during periods of attention to specific stimuli there are changes in the neural activity of central auditory structures; however, it is controversial whether attention can modulate auditory ...
    • Stimulus-dependent oscillations and evoked potentials in chinchilla auditory cortex 
      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. ...
    • Tamizaje universal de hipoacusia en el recién nacido 
      Alvo Vergara, Andrés; Der Mussa, Carolina; Délano, Paul H. (Hospital Clínico Universidad de Chile, 2010)
      Neonatal hearing loss affects 1-3 from every 1000 live newborns. For optimal language and social development, proper diagnosis and treatment must be established before the first 6 months of age. In Chile, screening for ...
