neocortex ↔ default mode network

Relations (1)

related 2.32 — strongly supporting 4 facts

The default mode network and the neocortex are related as the former is a functional system embedded within the latter, with the default mode network's evolution and activity hypothesized to be a primary driver of neocortex development [1], [2]. Furthermore, they are structurally linked as mammals share both systems [3], and the default mode network functions as a relay between the neocortex and the hippocampal memory system [4].

perspectiveThe author hypothesizes that innovation is the survival benefit that promoted the evolution of the neocortex, specifically the default mode network and its chaotic activity.

perspectiveThe noisy activity of the default mode network is hypothesized to be a 'feature' (the primary reason for neocortex evolution) rather than a 'bug' (an excess or side effect), given its role in creative problem-solving.

claimMany mammals possess similar innovation systems with similar interfaces because they share neural structures such as the neocortex, the claustrum (excluding monotremes), and the default mode network.

claimThe posterior regions of the default mode network (DMN) act as relays between the neocortex and the hippocampal memory system.
