Cortical Brain Functions ­ The Brodmann Legacy in the 21st Century

In 1909, Korbinian Brodmann described 52 functional brain areas, 43 of them found in the human brain. More than a century later, his devoted functional map was incremented by Glasser et al in 2016, using functional nuclear magnetic resonance imaging techniques to propose the existence of 180 functional areas in each hemisphere, based on their cortical thickness, degree of myelination (cortical myelin content), neuronal interconnection, topographic organization, multitask answers, and assessment in their resting state. This opens a huge possibility, through functional neuroanatomy, to understand a little more about normal brain function and its functional impairment in the presence of a disease.

Aspectos neurofuncionais do cerebelo: o fim de um dogma / Neurofunctional Aspects of Cerebellum: The End of a Dogma

Há séculos o cerebelo é considerado uma estrutura do sistema nervoso central responsável exclusivamente pela coordenação do movimento, fazendo diversas conexões com as áreas motoras e associativas do córtex cerebral. No entanto, nos últimos anos, avanços em neuroimagem funcional têm atribuído ao cerebelo funções cognitivo- afetivas, identificando-as anatômica e funcionalmente. Nesta revisão, os autores trazem as mais recentes informações sobre as funções cerebelares, considerando a síndrome cognitivo-afetiva correlacionada ao cerebelo e pondo fim a mais um dogma das neurociências.

For centuries the cerebellum is considered a structure of the central nervous system solely responsible for coordination of the movement, making several connections with themotor areas and associations areas of the cerebral cortex. However, in recent years, advances in functional neuroimaging has assigned the cerebellum cognitive-affective functions, identifying the anatomy and functionally pathways. In this review, the authors come with the latest information about the cerebellar functions, whereas the syndrome cerebellar cognitive-affective, it correlated, putting an end to more a dogma in neuroscience.
