On February 16, 2023, Frontiers in Neuroscience published a paper entitled Interconnected sub-networks of the macaque monkey gustatory connectome, by Senior Investigator Henry Evrard of ICPBR (Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences), in collaboration with long-time collaborators Renée Hartig (Nathan S. Kline Institute, USA) and Ali Karimi (Max Planck Institute for Brain Research, Germany). This research article reports on the organization of the macaque monkey gustatory connectome. Functional networks were identified by analyzing regional regression coefficients correlations and characterized using community detection and node centrality. These analyses revealed three interconnected sub-networks likely reflecting the general medial-lateral-subcortical organization of salience processing networks. The amplitude of response to taste and the strength of functional connectivity between sub-networks were modulated differently by sweet vs. sour and salty tastants, a modulation that could depend on the metabolic or hedonistic value of taste qualities.
