    Functional switching among dynamic neuronal hub-nodes in the brain induces maintenance/transition of cognitive states by Jasleen Gund, Yashaswee Mishra, B. N. Mallick, R. K. Brojen Singh

    Published 2025-01-01
    “…The switching behaviour in the ratio of hub/non-hub nodes between frontal and occipital regions during NREMS-Wake and Wake-NREMS transitions provides support as proof-of-principle of functional regional inactivation or activation of hub-nodes as the gradual switching mechanism towards transitioning of cognitive states in a graded (or non-flipping) manner, wake to sleep or vice versa; the detailed neuro-physio-chemical mechanism needs further study. Understanding sleep-wake transitions is vital for addressing sleep disorders, such as insomnia and sleep apnea. …”
