Human memory's remarkable capabilities find roots in the intricate brain anatomy.
Brain functions are localized in specific regions, yet the connections between these and the memory system remain unexplored.
Researchers used advanced imaging to uncover hidden cortical networks and shed light on memory's anatomical framework.
The study, published in Neuron, focuses on the medial temporal lobe (MTL) housing the memory system.
Precision neuroimaging allowed the team to scrutinize MTL anatomy with unprecedented detail, overcoming prior challenges.
They identified cortical networks linked to the human medial temporal lobe, revealing previously unknown aspects.
Daniel Reznik, the study's first author, highlighted the potential unveiling of new cortical pathways unique to humans.
The study enhances our understanding of human memory within anatomical constraints, informing evolution studies.
The findings hint at a recently evolved network linked to the human entorhinal cortex, influencing social processing.
This evolutionarily young network could have emerged after the cortex's expansion in humans.
