Unprecedented Detail in Mapping Neural Circuitry of Human Brain Tissue

Scientists find 57,000 cells and 150m neural connections in tiny sample of human brain 🔗

Harvard researchers teamed up with Google to analyse the makeup of the brain, much of which is not yet understood

Scientists have achieved an unprecedented level of detail in mapping the neural circuitry and connections in a small piece of human brain tissue, revealing new complexities and quirks. The study identified 57,000 cells, 150 million neural connections, and 23cm of blood vessels in a mere cubic millimeter of tissue. The findings, published in the journal Science, include unusual features such as symmetrical pyramidal neurons and strong connections between cells. The team's next project involves collaborating with Google to reconstruct the wiring of an entire mouse brain, aiming to gain insights into sensory experiences and free will.
