Biological naturalist Consciousness requires living metabolic hardware
Vinod Menon is the Stanford psychiatrist and neuroscientist behind the triple network model, which organizes large-scale brain dynamics around three interacting systems, the salience network, the default mode network and the frontoparietal network. His 2024 eLife study with first author Anup Das analyzed intracranial EEG from 177 participants across four episodic memory experiments and measured the direction of information flow between the networks with phase transfer entropy (DOI 10.7554/eLife.99018). Directed flow from the anterior insula, a key salience network node, to both default mode and frontoparietal nodes was consistently higher, and stronger during memory tasks than at rest.
That result gives the insula’s orchestrator role a measured direction and a task modulation, and it connects to a longer program on the salience network’s role in switching between internally directed and externally directed processing. The behavioral side has its own lesion evidence, the 2007 Science study by Naqvi and colleagues showing that insula damage disrupts smoking addiction, which the popular coverage of consciousness science often cites. For this site’s question, Menon’s work supplies the large-scale coordination layer that the oscillation literature operates within, and the site’s fact check of the ripples and vortices video keeps the measured claims and the stretched ones apart.
Known for. The triple network model of salience, default mode and frontoparietal networks, and the 2024 eLife iEEG study showing directed information flow from the anterior insula to the other two networks
