A Northwestern Medicine study published in Cell Reports reveals the correlation between two critical brain networks—the parietal memory network and salience network—involved in recognition memory. Researchers used high-resolution functional MRI imaging to analyze these networks in six participants and found they are not only interconnected but may function as a unified network. This discovery challenges past assumptions that separated these networks, highlighting a previously overlooked aspect of their interdependence and shared role in cognitive function.
We observed that the two networks are really correlated with each other to the point where you can logically say they're the same network.
We asked why do these two networks look different, when all the other networks have a similar distributed architecture?
These networks are organized into sequences of parallel networks, where the same sequence of networks can be observed in multiple parts of the brain.
Historically, the parietal memory network and the salience network have strayed from the pattern seen in other brain networks.
