Sistema límbico, Emoção, NeuroanatomiaResumo
Os sentimentos relacionados às emoções impulsionam a viver e geram reações diversas na relação do homem consigo e com o meio. O conhecimento das bases neurais dos processos emotivos teve grande avanço no final do século XX, a partir da neuroimagem e da neurofisiologia, quando foram descobertas novas conexões do Sistema Límbico (SL), como órgão subcortical, com áreas corticais cerebrais, que, em conjunto, atuam sobre o hipotálamo e o tronco encefálico. Objetivo. Revisar e discutir os aspectos atuais da neuroanatomia, pontuando, ainda, a importante relação entre os processos cognitivos, emocionais, os componentes autonômicos e somatomotores. Método. Revisão da literatura com aspectos históricos do SL. Resultados. Exposição das principais vias e circuitos neurais envolvidos com as emoções, seguindo-se uma discussão sobre as principais emoções. Conclusão. Conhecer as conexões neurais, no que se refere às emoções, é muito importante para o ensino e a pesquisa que poderão motivar novas descobertas na neuroanatomia.
