These substances are capable of influencing human behavior, affecting mental health, which, despite being a much-discussed topic, is little studied in terms of the production of these receptors. Thus, the objective of the work is to explore this theme, evaluating the way in which the imbalance of these chemical substances affects the individual's behavior and emotions. For that, a bibliographic survey was carried out, followed by data collection, from the application of a virtual form, aiming to evaluate the level of knowledge that the community had about the proposed theme. This questionnaire was applied in the city of Penedo- AL, with 63 volunteer participants. It was found that only 8% of the population of penedense understood neurotransmitters, evidencing the scarcity of research and theoretical deepening of the theme addressed. In addition, 62% of respondents reported behavioral changes whe comparing the pre and post pandemic period. This shows that the imbalance of neurotransmitters resulting from social isolation and a feeling of insecurity reflects negatively on human behavior, generating disorders and mental illnesses. Therefore, it is extremely important to understand the role of these brain receptors as modulators of emotions, so that people can have a healthier and longer life.Acesso AbertoSaúde mentalPandemiaNeurotransmissoresTrabalho de Conclusão de CursoCiências da Saúde
