The Nucleus of the Solitary Tract (NTS) receives gustatory and visceral information from afferent fibers in the vagus and projects to the Nucleus Paragigantocellularis (PGi), among several other brain region. PGi sends excitatory fibers, mostly glutamatergic, to the Locus Coeruleus (LC). In turn, LC sends noradrenergic projections to many areas of the(More)
THE PROCESS OF TEACHING and learning at the undergraduate level is challenged by an increasing amount of content (1). Now it’s not enough to convey knowledge; it’s also necessary to seek alternative ways to motivate and capture the interest of students both during class and outside of class. Currently, social networks are popular among students (5) and are(More)
We investigated the effects of physical exercise and green tea supplementation (associated or not) on biochemical and behavioral parameters in the time course of normal aging. Male Wistar rats aged 9 months were divided into groups: control, physical exercise (treadmill running), and supplemented with green tea while either performing physical exercise or(More)
Ischemic stroke is a major cause of morbidity and mortality all over the world. Among impairments observed in survivors there is a significant cognitive learning and memory deficit. Neuroprotective strategies are being investigated to minimize such deficits after an ischemia event. Here we investigated the neuroprotective potential of physical exercise and(More)
This work examines the effects of chronic exposure to low inorganic mercury (mercury chloride, HgCl(2)) concentration on the recognition and aversive memories. Forty male Wistar rats were divided into 4 groups treated during 30 or 60 days with saline (control) or HgCl(2) doses. After treated the animals were tested considering object recognition and(More)
Extinction is the learned inhibition of retrieval. Recently it was shown that a brief exposure to a novel environment enhances the extinction of contextual fear in rats, an effect explainable by a synaptic tagging-and-capture process. Here we examine whether this also happens with the extinction of another fear-motivated task, inhibitory avoidance (IA), and(More)
Previous research has shown that crotamine, a toxin isolated from the venom of Crotalus durissus terrificus, induces the release of acetylcholine and dopamine in the central nervous system of rats. Particularly, these neurotransmitters are important modulators of memory processes. Therefore, in this study we investigated the effects of crotamine infusion on(More)
BACKGROUND With aging, it is important to maintain cognitive and motor functions to ensure autonomy and quality of life. During the acquisition of motor skills, it is necessary for the elderly to understand the purpose of the proposed activities. Physical and mental practice, as well as demonstrations, are strategies used to learn movements. OBJECTIVES To(More)
Members of the Education Committee of the Brazilian Society of Physiology have developed multiple outreach models to improve the appreciation of science and physiology at the precollege level. The members of this committee act in concert with important Brazilian governmental strategies to promote training of undergraduate students in the teaching(More)
BEGINNING IN THE 1980S, the Brazilian government introduced strategies to promote universal access to primary education, which coincided with an increase in the number of 6-yr-old children entering the educational system and the expansion of the public high school system (10). More recently, recognition of the importance of access to education at different(More)
