Daher würde das Scannen des gesamten menschlichen Gehirns mit der im Artikel genannten Auflösung einen Wert zwischen zwei und mehr erfordern 1,82 Zettabyte Und 2,1 Zettabyte von Speicherdaten basierend auf dem durchschnittlich großen Gehirn.

I thought if the prospect of digitizing the human brain’s neural complexity suggests future possibilities for creating digital twins that emulate a person’s thoughts and memories. While current technology allows us to map brain data to an extensive degree—requiring storage in the zettabytes—it also poses significant ethical and philosophical questions. Advances in AI, like large language models, could facilitate the interpretation and interaction with such vast data, potentially leading to personalized digital twins. What are your thoughts?
Here’s a concise summary for Reddit:
**Title:** Groundbreaking 3D Brain Map Unveiled
**Summary:**
Scientists have achieved a monumental feat in neuroscience by reconstructing a cubic millimeter of the human brain in 3D, offering an unprecedented glimpse into its intricate structure. This nanoscale project, which consumed over 1.4 petabytes of electron microscopy data, reveals a staggering 57,000 cells, 150 million synapses, and 230 millimeters of blood vessels—all within a space no larger than a grain of sand.
The Harvard-led team’s decade-long effort has resulted in the most detailed brain model to date, down to the synaptic level. This „connectome“ could revolutionize our understanding of brain function and disorders, potentially accelerating advancements in treating conditions like dementia and mental illness.
The sample, obtained from an epilepsy patient, was meticulously imaged and reconstructed, uncovering new cellular patterns and connections. Such detailed mapping is a significant step towards the larger goal of replicating an entire mouse brain, and eventually, segments of the human brain.

To me, this looks like a dent in the “live forever via mind uploading” Argument. If 1 cubic millimeter of brain took 1.4 PETAbytes (that‘s 1.4 MILLION GIGABYTES) , then imagine how much the whole brain must take up…
