The 3Dmorphospace leverages data from over three decades of functional neuroimaging research, combining insights from thousands of fMRI studies contained in the Neurosynth database. This meta-analysis created a visual map that shows how different brain areas interact to carry out various cognitive tasks, from language processing to memory and attention.
Stephanie Forkel, a leading researcher in the study, explained: "We created a 3D space that uses advanced embedding techniques to simplify complex brain data, offering a clearer view of how different cognitive functions are organized."
Map of undiscovered brain functions
One of the most exciting features of the 3Dmorphospace is its ability to predict and decode unseen brain functions. By mapping known cognitive branches such as language and memory, the tool identifies "gaps"—areas of the brain where no current cognitive functions are mapped but where potential functions likely exist. This opens up new avenues for researchers to explore these underexplored aspects of brain activity.
Forkel noted that the study’s implications are vast: “The 3Dmorphospace looks like a neuron with a cell body and branches representing various cognitive functions. The space between these branches is fascinating because there are entire cognitive functions we have not yet discovered.” This discovery paves the way for future research, offering a map for young scientists to investigate the brain’s undiscovered functions.
Applications and future directions
3Dmorphospace offers a wealth of possibilities for decoding human cognition, from predicting brain functions to unlocking insights into emotions and thoughts. As researchers explore the “gaps” in the cognitive map, the framework is expected to guide discoveries in both healthy and disordered brain functions.
Forkel is already planning follow-up studies, including research on the intersection between music and language, further illustrating how the 3Dmorphospace can be applied to explore previously uncharted cognitive territory.
