Europe spent 600 million euros to recreate the human brain in a computer. What was the result?

The Human Brain Project (HBP), a pioneering attempt to understand the complexities of the human brain, has come to an end after a decade of research. The project, which had the audacious goal of modeling the human brain in a computer, brought together some 500 scientists and received €600 million in funding from the European Union. Despite the fact that the HBP project did not achieve its original goal, it has made a significant contribution to the development of neuroscience and paved the way for future advances in this field. This is reported in the journal Nature

A Revolution in Neuroscience: Achievements of the Human Brain Project

Throughout the lifetime of the HBP project, significant advances have been made that have expanded our understanding of the brain. Here are some notable achievements:

1. Detailed three-dimensional maps of the brain: Scientists working within the HBP program have created detailed three-dimensional maps of more than 200 brain regions. These maps provide invaluable insight into the structure and connections of the human brain.

2. Brain Implants to Treat Blindness: The HBP has developed brain implants that may help treat blindness. By interacting with the visual cortex of the brain, these implants can restore sight to those who have lost it.

3. Supercomputers for brain modeling: Using the power of supercomputers, researchers have successfully modeled functions such as memory and consciousness. This breakthrough has opened the door to improved treatments for various brain diseases.

Challenges and criticisms: Roadblocks faced by HBP

Despite its achievements, HBP has faced criticism and obstacles along the way. Here are some of the challenges faced by this ambitious project:

1. Unrealistic goal of modeling the entire human brain: The goal of the HBP project was to model the entire human brain, and many scientists considered this goal far-fetched from the beginning. As a result, the project changed direction repeatedly, resulting in fragmented and mosaic scientific results.

2 Lack of comprehensive understanding: Yves Frégnac, a cognitive scientist and HBP member, expresses frustration that the project has failed to provide a comprehensive or original understanding of the brain. Instead of seeing the brain as a whole, he sees only fragments of it.

EBRAINS: the future of brain research

Despite its shortcomings, the HBP project has laid the groundwork for future advances in neuroscience. One such achievement is the creation of the EBRAINS virtual platform, which provides scientists around the world with tools and visualization data for simulations and digital experiments. With EBRAINS, scientists hope to get closer to creating a real digital twin of the human brain.

An Uncertain Future: Funding Challenges and the Fight Against Time

Despite the great potential of EBRAINS, its funding remains uncertain. While other countries are embarking on their own ambitious brain research projects, scientists in Europe are frustrated by the winding down of the HBP project. Jorge Mejias, a computational neuroscientist at the University of Amsterdam, laments the lack of time to relax as everyone rushes to make groundbreaking discoveries.

Looking to the Future: The Legacy of the Human Brain Project

The Human Brain Project may not have achieved its lofty goal of modeling the entire human brain, but it has made significant contributions to neuroscience. Its advances in brain mapping, implant technology, and supercomputers have paved the way for future discoveries. As science continues to unravel the mysteries of the human brain, HBP’s legacy will undoubtedly shape the future of neuroscience.
