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. The students considered important the use of this type of methodology, which uses different online tools to help understand the Human Physiology contents. The students highlighted the use of the Lt platform, Zoom, Mentimeter, and YouTube as the preferred online tools to use in physiology learning.

A pandemia da COVID-19 se disseminou amplamente de forma substancial e impôs à sociedade uma nova forma de realizar suas atividades cotidianas, incluindo as atividades de ensino, pesquisa e extensão universitária. Dessa forma, professores e cientistas de todo o mundo, na tentativa de dar continuidade as suas atividades e adaptar-se ao distanciamento social, estão utilizando plataformas de redes sociais, que representam uma das ferramentas de comunicação mais eficazes e populares hoje em dia. Neste sentido, aqui nós relatamos nossas experiências para a manutenção do programa de extensão POPNEURO durante o período de distanciamento social. Nós intensificamos nossas atividades de divulgação da neurociência pelas redes sociais, utilizando a rede social Instagram como veículo de comunicação. Nossos resultados indicam que esta plataforma pode ser utilizada para a divulgação de conteúdos de neurociência, podendo ser uma forma eficaz para a disseminação de conhecimento e aproximação da universidade-comunidade em tempos de pandemia.

Strategies for improving memory are increasingly studied, and exposure to a novel experience can be an efficient neuromodulator. Novelty effects on memory depend on D1‐family dopamine receptors (D1Rs) activation. Here, we evaluated the novelty effect on memory persistence of Wistar rats and investigated the contribution of D1Rs and their signalling pathways by protein kinase A (PKA) and C (PKC). Animals with infusion cannulae inserted into the CA1 hippocampus area were trained on the novel object recognition (NOR) task, which involved exploring two different objects. After training, some rats received intrahippocampal infusions of vehicle or D1Rs agonist; others explored a novel environment for 5 min and were infused with a variety of drugs targeting D1Rs and their signalling pathways. We demonstrated that pharmacological stimulation of D1Rs or novelty exposure promoted NOR memory persistence for 14 days and that the novelty effect depended on D1Rs activation. To determine if the D1 and D5 receptor subtypes were necessary for the impact of novelty exposure on memory, we blocked or stimulated PKA or PKC—protein kinases activated mainly by D1 and D5, respectively. Only PKA inhibition impaired the effect of novelty on memory persistence. After novelty and D1Rs blocking, PKA but not PKC stimulation maintained the memory persistence effect. Thus, we concluded that novelty promoted memory persistence by a mechanism‐dependent on activating hippocampal D1Rs and PKA pathway.
