(1988)A data acquisition program is described for the Apple II series of microcomputers that allows for continuous, direct monitoring of electrographic elements from cortical, hippocampal and muscle leads from rats. The program ...
-
(Universidad de Chile, 2010)Autores en los 70’s y 80’s reportaron que el Enriquecimiento Ambiental (EA) aumentaba selectivamente el sueño REM. Ellos relacionaron estos resultados con los procesos de aprendizaje que serían mayores en ratas que tienen ...

(2014)Study Objectives: Given the detailed respiratory waveform signal provided by the nasal cannula in polysomnographic (PSG) studies, to quantify sleep breathing disturbances by extracting a continuous variable based on the ...
-
(1990)In the sixties and seventies, the School of Medicine of the University of Chile was the first Chilean institution to incorporate computers into academic endeavors through its own Computer Center. Later, professors were ...
-
(1990)Projects on informatics at the School of Medicine of the University of Chile are being brought about in accordance with both its institutional goals and present trends in technology. Prominent among the latter are the ...
-
(2013)El golpe de Estado de 1973 afectó a la Universidad de Chile al menos en tres modalidades de embates y conminaciones. La primera se expresa en las interacciones directas del régimen dictatorial con ella, es decir, la ...
-
(Associated Professional Sleep Societies,LLC, 1994)Distributions within a 12:12 light:dark schedule of wakefulness (W), active sleep (AS), quiet sleep (QS) and of QS rich in delta (QSD) and in spindle (QSS) activities were evaluated for 52 days from 15 rats. Angular ...
-
(Universidad de Chile, 1995)El autor revisa la situación actual de la Universidad de Chile a partir de sus postulados fundacionales, haciendo hincapié especialmente en el destino de los discursos de los '60 y aun anteriores, confrontados con lo ...

On-line analysis of biosignals for the automation of total and specific sleep deprivation in the rat (SOC BIOLGIA CHILE, 2008)A computer-based system that automates sleep studies, including sleep deprivation paradigms, is described. The system allows for total or REM-specific sleep deprivation and is based on a reliable, fast-responding, ...
-
(Frontiers Research Foundation, 2017)Operant extinction is learning to supress a previously rewarded behavior. It is known to be strongly associated with the specific context in which it was acquired, which limits the therapeutic use of operant extinction ...

(Universidad de Chile, 2007)Los estudios de privación de REM típicamente apuntan a la homeostasis de largo plazo, por lo cual se han llevado a cabo privaciones de larga duración de REM, las cuales tenían una prolongación en el tiempo de algunas horas ...
-
(American Physiological Society, 1994)1. Sixteen rats were recorded continuously for 3 days using an automated system that detected, quantified, and stored the incidence of cortical delta waves, cortical sigma spindles, hippocampal theta rhythm, and electromyographic ...
-
(2002)An intermittent rapid eye movement (REM) sleep deprivation protocol was applied to determine whether an increase in REM sleep propensity occurs throughout an interval without REM sleep comparable with the spontaneous sleep ...
-
(1991)A microcomputer-based system is described that detects, counts and stores cortical delta and sigma waves, hippocampal theta waves and electromyographic activities in the rat by building matrices with the incidence of those ...
