Software tool brings together multiple brain maps in one place

0

The brain is a complex organ, and no imaging mode can capture everything that happens there. Over the years, multiple “brain maps” have emerged, each focusing on different brain processes, from metabolism to cognitive function. While these maps are important, their use in isolation limits the discoveries that researchers can make from them.

Today, a team from The Neuro has brought over forty existing brain maps together in one place. The database, called neuromaps, will help scientists find correlations between patterns in different brain regions, spatial scales, modalities and brain functions. It provides a standardized space to view each map against the other, and assesses the statistical significance of these comparisons, to help researchers distinguish a significant correlation from a random pattern. The neuromaps database also helps standardize the code on the maps, to improve the reproducibility of results.

The team published their findings in the journal Natural methods on October 6, 2022 and made their data freely available on github.

“Ultimately, we hope neuromaps will add a spark to the analysis of human brain maps and increase the accessibility of data and software tools to people with diverse research interests,” says Justine Hansen, co- first author of the article. “As the rate at which new brain maps are generated in the field continues to increase, we hope neuromaps will provide researchers with a set of standardized workflows to better understand what this data can tell us about the human brain. .”

This study was funded with the help of Fonds de Recherche du Québec — Nature et Technologies (FRQNT), Canadian Open Neuroscience Platform (CONP), Hemlholtz International BigBrain Analytics and Learning Laboratory (HIBALL), Natural Sciences and Engineering Research Council of Canada (NSERC), Canada Research Chairs (CRC), National Institutes of Health (NIH), Canadian Institutes of Health Research (CIHR), Healthy Brains for Healthy Lives (HBHL) and Brain Canada Future Leaders (BCF).
