Newly published new brain maps identify five new areas within the dorsolateral prefrontal cortex (DLPFC), that plays a crucial role in executive functions, including working memory, decision-making, and attention. The new study introduces 3D maps of cytoarchitectonic regions, enhancing our understanding of the prefrontal cortex's complexity.
The study is an important step toward deciphering the structural-functional organization of the human prefrontal cortex. By analyzing series of histological sections and employing state-of-the-art statistical techniques, Bruno & Lothmann et al. identified and mapped five new areas within the DLPFC, and revealed their variations across brains. The three-dimensional maps will be part of the next release of the Julich Brain Atlas, which is freely accessible via the EBRAINS research infrastructure.
