Google and Harvard researchers present the most detailed map of the human brain to date

On the other hand, today pathologies can be reproduced in cell cultures or organoids. However, there are very few models that reliably reflect diseases affecting the brain. Moreover, although animals are fairly good models for studying some diseases, their brains—and even the brains of other primates—are radically different from our own. To fill the gaps, many atlases have been created to map the connections between neurons in the human brain, but most of them have only limited resolution. This type of atlas, called a “connect,” allows us to trace the complexity of connections at the level of an individual neuron. According to the Harvard and Google team, nanoscale mapping is necessary to expand our understanding of how the brain works and the mechanisms of the diseases that affect it.
