Acute physical exercise prevents memory amnesia caused by protein synthesis inhibition in rats' hippocampus.

The benefits of physical exercise (PE) on memory consolidation have been well-documented in both healthy and memory-impaired animals. However, the underlying mechanisms through which PE exerts these effects are still unclear. In this study, we aimed to investigate the role of hippocampal protein synthesis in memory modulation by acute PE in rats.

The Sobering Sting: Oleoyl Serotonin Is a Novel Snail Venom-Derived Antagonist of Cannabinoid Receptors That Counteracts Learning and Memory Deficits.

Cannabinoid receptors (CB1 and CB2) are promising targets for a better understanding of neurological diseases. Nevertheless, only a few ligands of CB have reached clinical application so far. Venoms are considered as interesting sources of novel biologically active compounds.

Egg White Hydrolysate Mitigates Cadmium-induced Neurological Disorders and Oxidative Damage.

We aimed to investigate whether the consumption of Egg White Hydrolysate (EWH) acts on nervous system disorders induced by exposure to Cadmium (Cd) in rats. Male Wistar rats were divided into (a) Control (Ct): HO by gavage for 28 days + HO (i.p.

Long-term impact of neuroscience outreach interventions on elementary students' knowledge.

Neuroeducation is characterized as a subarea of neuroscience that involves comprehending the teaching and learning processes and relating them to neuroanatomy, neurophysiology, and neuropsychology. The inclusion of some aspects of the neuroscience of learning in teachers' and students' formation, applying them in teaching-learning environments, contributes to the quality of education and impacts students' quality of life and health. Thus, the POPNEURO outreach program performs interventions with students and teachers of low-income schools to disseminate neuroscience concepts, relating them to the students' daily lives.

Acute physical exercise enhances memory persistence in female rats.

Memory is a complex cognitive process with distinct stages, such as acquisition, consolidation, and retrieval. The hippocampus plays a crucial role in memory consolidation and retrieval. Physical exercise (PE) has been shown to enhance memory and cognitive functions, but the available research is mainly developed with males.

Acute physical exercise improves recognition memory via locus coeruleus activation but not via ventral tegmental area activation.

Both animals and humans have been studied to explore the impact of acute physical exercise (PE) on memory. In rats, a single session of PE enhances the persistence of novel object recognition (NOR) memory, which depends on dopamine and noradrenaline activity in the hippocampus. However, limited research has examined the involvement of other brain regions in this phenomenon.

Starting maternal exercise, unlike reducing the intensity of exercise during pregnancy, prevents memory deficits in female offspring subject to maternal deprivation.

Maternal deprivation (MD) leads to long-lasting memory deficits. Conversely, maternal exercise could potently modify the offspring's cellular machinery. Here, we tested whether starting to run or reducing the intensity of running during pregnancy can protect prepubertal female offspring against MD-induced memory deficits.

Student assessment of online tools to foster engagement during the COVID-19 quarantine.

As a result of the installation of the COVID-19 (coronavirus disease 19) pandemic, online education has become an important teaching alternative, and new challenges about how to teach were found. Here we report our experience in offering an online course to review Human Physiology. We proposed synchronous and asynchronous activities using different online tools to address topics considered key to understanding the different systems of human physiology.

One-single physical exercise session after object recognition learning promotes memory persistence through hippocampal noradrenergic mechanisms.

Previously we showed the involvement of the hippocampal noradrenergic system in the consolidation and persistence of object recognition (OR) memory. Here we show that one-single physical exercise session performed immediately after learning promotes OR memory persistence and increases norepinephrine levels in the hippocampus. Additionally, effects of exercise on memory are avoided by an intra-hippocampal beta-adrenergic antagonist infusion.
