(2010)Prenatal undernutrition induces hypertension later in life, possibly by disturbing the hypothalamo-pituitary-adrenal axis through programming decreased expression of hypothalamic glucocorticoid receptors. We examined the ...

Soto Moyano, Rubén; Hernández, Alejandro; Ruiz, Samuel; Pérez, Hernán; Paeile, Carlos (1978)The influence of pentazocine on primary cortical evoked potentials was studied in guinea pig under pentobarbital anesthesia. Pentazocine (10 mg/kg, i.v.) increased the latency time of evoked responses to posterior limb ...
-
Pérez, Hernán; Ruíz, Samuel; Hernández, Alejandro; Soto Moyano, Rubén (1983)Cortical reactivity of parietal association area was studied in normal and undernourished rats. (i) The normal group was from mothers which were fed a 21.5% protein diet during lactation. (ii) The undernourished group was ...

Laurido, Claudio; Pelissier Serrano, Teresa; Pérez, Hernán; Flores, Francisco; Hernández, Alejandro (Lippincott Williams and Wilkins, 2001)The effects of systemically and intrathecally administered ketamine on spinal wind-up of normal and monoarthritic rats were studied by using C-fiber reflex responses evoked by repetitive (0.6Hz) electric stimulation. Both ...

Hernández, Alejandro; Burgos, Héctor; Mondaca, Mauricio; Barra, Rafael; Núñez, Héctor; Pérez, Hernán; Soto Moyano, Rubén; Sierralta, Walter; Fernández, Victor; Olivares, Ricardo; López Valladares, Luis (Hindawi Publishing Corporation, 2008)Reduction of the protein content from 25 to 8% casein in the diet of pregnant rats results in impaired neocortical long-term potentiation (LTP) of the offspring together with lower visuospatial memory performance. The ...

Flores, Osvaldo; Pérez, Hernán; López Valladares, Luis; Morgan, Carlos; Gatica, Arnaldo; Burgos, Héctor; Olivares, Ricardo; Hernández, Alejandro (2011)Moderate reduction in the protein content of the mother's diet (hidden malnutrition) does not alter body and brain weights of rat pups at birth, but leads to dysfunction of neocortical noradrenaline systems together with ...
-
Pérez, Hernán; Hernández, Alejandro; Almli, C. Robert (1987)Field-evoked potentials from the main olfactory bulb in response to stimulation of the olfactory nerve and lateral olfactory tract were measured without and with conditioning stimulation of the locus coeruleus noradrenergic ...
-
Pérez, Hernán; Ruiz, Samuel; Hernández, Alejandro; Soto Moyano, Rubén (1985)Susceptibility to strychnine of somatosensory responses evoked in the prefrontal cortex was studied in normal and protein-malnourished rats in three groups. (a) The normal group was from mothers fed a 21% casein diet. (b) ...
-
Pérez, Hernán; Ruiz, Samuel (1995)The effect of electrical and L-glutamate stimulation of the nucleus locus coeruleus (LC) and nucleus raphe magnus (NRM) on multiunit activity evoked in the nucleus tractus solitarius (NTS) by activation of arterial ...
-
Ruiz, Samuel; Pérez, Hernán; Hernández, Alejandro; Ramirez, Maritza; Fernandez, Monica; Soto Moyano, Rubén (Informa Healthcare, 1986)The effect of early postnatal malnutrition on the responsiveness of the rat prefrontal cortex was studied by determining excitability thresholds and fatigability to direct cortical stimulation. Malnutrition imposed during ...

Soto Moyano, Rubén; Alarcon, Sergio; Hernández, Alejandro; Pérez, Hernán; Ruiz, Samuel; Carreño, Paz; Kusch, Claudia; Belmar, Jorge (1998)Prenatal malnutrition results in increased concentration and release of central noradrenaline, a neurotransmitter that is an important regulator of normal regressive events such as axonal pruning and synaptic elimination. ...
-
Pérez, Hernán; Ruiz, Samuel; Soto Moyano, Rubén (2002)Prenatal malnutrition-induced fetal growth retardation in the rat results in elevated arterial blood pressure at adulthood. To test the contribution of cardiovascular sensory C fibers in the hypertensive state, arterial ...

Navarrete, Mario; Núñez, Héctor; Ruiz, Samuel; Soto Moyano, Rubén; López Valladares, Luis; White Ortiz, Allan; Pérez, Hernán (2007)Prenatal undernutrition is known to disturb the hypothalamo-pituitary-adrenal (HPA) axis, possibly through the programming of decreased expression of hypothalamic and pituitary glucocorticoid receptors. To test this ...
