Article summary

Researchers have mapped a cubic millimeter of the human brain at nanoscale resolution, revealing new patterns of connections between brain cells and other cellular structures. The resulting cell atlas is available online and provides detailed information about the brain's neural connections. This achievement is a significant step forward in understanding the brain's complexity and may lead to new insights into brain function and behavior. The study used electron-microscope data to create a detailed rendering of the brain's neural connections.

What commenters say

  • The brain's complexity and density of neural connections may be related to its computational power and ability to process information.
  • The comparison between bird and mammalian brain architectures is not straightforward, and each has its own unique characteristics and trade-offs.
  • The speed of signal propagation in the brain is slow due to its chemical and electrical nature, which may impact its computational abilities.
  • The study of brain morphology and connectome has significant implications for our understanding of brain function and behavior.
  • The achievement of mapping a cubic millimeter of the brain is a significant step forward, but the complexity of the brain is still not fully understood.
  • The brain's ability to understand itself is still an open question, and it is unclear whether it is even logically possible.
  • The density of neurons in bird brains, such as those of crows, may be related to their intelligence and cognitive abilities.
  • The trade-offs between different brain architectures, such as those of birds and mammals, may be due to different evolutionary pressures and constraints.
