Summary: A new AI-Powered atlas called Nextebrain allows researchers to visualize the human brain in unprecedented detail, down to hundreds of tiny fields previously unseen in MRI Scans. Built from 10,000 microscopic slices of post-mortem brain and aligned with AI, the Atlas directly maps 333 brains in 3D.
When tested on thousands of MRI Scans, it identifies complex expressions of the brain quickly and consistently, previous tools. Open Atlases will accelerate global research into aging, neurodegenerative diseases, and brain development, developing early diagnosis and new treatments.

A new AI-assisted atlas that can help see the human brain in unprecedented detail has been developed by UCC researchers, at the forefront of neuroscience and neuroscience.
The human brain includes hundreds of interconnected regions that drive our thoughts, feelings, and behaviors. Existing brain atlases can identify large structures in MRI Scans – such as the Hippocampus, which supports memory and learning – but their best regions remain elusive.
These differences are due to lower regions of areas such as the hippocampus, for example, being affected differently during the progression of Alzheimer's disease.
Examining the brain at the cellular level is accessible using microscopy (histology), but it cannot be done in living people, limiting its ability to understand how the human brain changes during development, aging and disease.
Published internally Kind ofNew research presents Nextebrain, an Atlas of the entire adult population that can be used to analyze MRI Scans of living patients in a matter of minutes and at a level of detail not possible until now.
The creators of the Atlas, which is freely available, hope that it will help accelerate the discovery of brain science and its translation into better calculations and treatment of conditions such as Alzheimer's.
Atlas Atlas Attas Ayize Ai
The atlases took a research team six years to build through a painstaking process to complete a jigsaw puzzle – one made using post-human tissue.
Each Bot Brow was disrupted and divided into 10,000 pieces, focused to help identify brain structures, photographed under a microscope, and assembled into a 3D digital model. Before they started this process, the team did MRI Scans of the Brains to know how to put them back together, not unlike the picture on the front of the jigsaw box.
AI was used to help synchronize the microscope images and MRI Scans, calculate the differences between the two processes and ensure that the pieces did not overlap or have gaps between them.
A total of 333 brain regions were then mapped onto digital 3D models of each of the five brains, a process greatly accelerated by AI. Made by hand, researchers say it would have taken decades.
Dr. Juan Eugenio Iglesias, senior author of the study from UCL medicine and biomedical engineering and Massachusetts General Hospital / Harvard Medical Hospital / Harvard Medical, “NextBrain is the end of years of effort with MRI.
By combining advanced tissue data with advanced tissue AI, we have created a tool that allows researchers to analyze brain scans at a level of detail previously available. This opens up new opportunities for studying neurodegenerative diseases and aging. “
The resulting atlases, i.e. 'averages' of five brain models, are common to all adults – meaning that information from MRI Scans of living or deceased can be used automatically.
The accuracy of Brain Atlas has been tested on thousands of scans
NextBrain has been successfully tested on thousands of MRI datasets, demonstrating the ability to reliably display brain regions in various mental states and situations.
In one experiment, the team used Atlas to automatically bring brain regions into a publicly available ultra-high resolution scan, which closely matches handwritten regions, even in small areas with the hippocampus.
In one experiment, researchers used NextBrain to scan up to 3,000 iSkena Scans of living people to investigate age-related changes in brain volume. The atlases enabled a more detailed analysis of aging patterns than could be obtained using existing tools.
Dr. Zane Jaunmuktane, author of the study from the UCL Queen Square Institute of Neurology and the Queen Square Brain Bank for Neuromical Disturbance of Biological Information immediately, and the level of anatomical information in the adteral. And its public availability means that Investigators all over the world can benefit from it immediately.
“NextBrain provides an unparalleled map of the clartal structure of the brain. The foundation built on the Atlas now makes the first signs of neurology, and before finding the signs of understanding, monitoring and ultimately preventing these devastating diseases.”
All the basic information, tools, and annotations used in NextBrain have been released publicly through the Freesurfer neuroimigh planet, as well as visualization tools and educational resources.
Funding: This study is supported by the European Research Council, the Alzheimer's Society, the Lundbeck Foundation, and the National Institutes of Health (US).

A historical probonabIlistic atlas of the human brain for MRI segmentation
In human interaction, brain atlases are important for distinguishing regions of interest (ROIS) and comparing subjects in a common coordinate frame.
State-of-the-art histology-based atlases provide high-resolution cytoarchitective maps but cross probiker labels
Here we present NextBrain, a probabilistic historical atlas of the entire human brain.
We have developed artificial methods that have enabled the synchronization of approximately 10,000 sections of history from the complete generals of the hemispheres into three-dimensional volumes and produced the deletion of 333 roles in these sections. We also developed a near-automated Bayesian tool for these ROS in Magnetic Resonance imaging (MRI) Scans.
We demonstrate two uses of Atlas: Ultra-High-Resolution Ex Vivo MRI classification and volumetric analysis of Alzheimer's disease using eVivo MRI. We publicly release raw and aligned data, an online viewing tool, atlases, a logging tool, and a veritable fact to establish the Ex-hemisphere top used with verifiability.
By enabling researchers around the world to automatically analyze MRI brains at a higher level of granularity, Nextebrain holds the promise of increasing the specificity of health and disease findings.
