The brain is arguably the most complex object in the known universe, and neuroscience—the discipline charged with understanding it—has grown to match that complexity. Today, the field spans everything from the molecular choreography of a single synapse to the large-scale network dynamics that give rise to conscious experience. It is simultaneously one of the most exciting and most disorienting fields to work in. The conceptual map that connects our different subfields hasn’t been written yet.
What emerges is a portrait of a discipline that is, in many ways, healthier than it might appear from the inside.

But a new study published in Aperture Neuro in February takes a remarkable step toward drawing that map. Led by Mario Senden, a computational neuroscientist at Maastricht University, the work applies state-of-the-art text embedding and community detection algorithms to nearly half a million neuroscience abstracts published between 1999 and 2023. It carves the literature into 175 distinct research clusters, characterizing each one along dimensions ranging from spatial scale to theoretical orientation.
What emerges is a portrait of a discipline that is, in many ways, healthier than it might appear from the inside. Despite its staggering diversity—clusters range from AMPA receptor trafficking to the neural underpinnings of consciousness—the field is remarkably well integrated; the vast majority of research communities actively draw on and feed into one another. The cluster of resting-state functional MRI dynamics and the molecular mechanisms of hippocampal plasticity emerge as some of the field’s great intellectual hubs, providing conceptual and methodological scaffolding for dozens of downstream communities.
