Por primera vez, científicos de Harvard detallaron cómo es un milímetro cúbico de cerebro

Researchers from Harvard and Google have reconstructed an unprecedented 3D map of a small portion of the human brain, using high-resolution electron microscopy combined with machine learning algorithms. This monumental effort, which took nearly a decade, allowed them to visualize with nanoscale detail the complex neural connections, support cells, and vascular network within a tiny volume of tissue. The research revealed structures and connectivity patterns not previously documented in textbooks, such as unusual symmetries in dendrites and exceptionally strong axonal connections that could explain the automation of learned behaviors. These findings highlight the vast gap between current knowledge and the biological reality of the brain, suggesting that its functionality is more closely tied to sensory experience and practice than previously believed. This study is pivotal for the open data movement in science, as the team decided to make part of the map freely available online to ensure that the substantial public and private investment benefited the entire scientific community. By sharing these terabytes of information, they set a critical precedent for the reuse and collaborative analysis of complex data, accelerating research in connectomics and paving the way for more comprehensive brain maps in the future.
