Depois de ter viajado em busca de lugares belos e decadentes, eis que tenho notícia de mais uma descoberta. E esta é das boas e, ainda por cima, relacionada com a parte mais misteriosa do nosso corpo: o cérebro.

| Researchers have divided the brain into discrete areas based on structure and function |
Transcrevo:
Human brain mapped in unprecedented detail
Nearly 100 previously unidentified brain areas revealed by examination of the cerebral cortex.
Think of a spinning globe and the patchwork of countries it depicts: such maps help us to understand where we are, and that nations differ from one another. Now, neuroscientists have charted an equivalent map of the brain’s outermost layer — the cerebral cortex — subdividing each hemisphere's mountain- and valley-like folds into 180 separate parcels.
Ninety-seven of these areas have never previously been described, despite showing clear differences in structure, function and connectivity from their neighbours. The new brain map is published today in Nature. (...)
But the map is limited in some important ways. For one, it reveals little about the biochemical underpinnings of the brain — or about the activity of single neurons or small groups. “It is analogous to having a fantastic Google Earth map of your neighbourhood, down to your individual back yard,” says Jung. “Yet, you cannot really see how your neighbours are moving around, where they are going or what sort of jobs they have.”(...)
Mas vejamos o vídeo que foi divulgado esta quarta-feira. Ainda está quentinho.
The ultimate brain map
A new map of the human brain could be the most accurate yet, as it combines all sorts of different kinds of data. This might finally solve a century of disagreements over the shapes and positions of different brain areas.

E agora que já sabem muito bem onde fica o bocadinho do vosso cérebro que é responsável pelo vosso hábito de ler o Um Jeito Manso, deixem-se deslizar por aí abaixo porque, se este não vos convenceu, há mais dois posts novos e pode ser que gostem de algum.
