Brain waves are rhythmic voltage oscillations emerging from the synchronization of individual neurons into a neuronal network. These oscillations emerge in all brain regions, and their patterns of synchrony and coherence underlie the neural code for sensory representation and short-term memory. Network oscillations range from slow to fast fluctuations and are classified by power and frequency band, with different frequency bands being associated with specific behaviours, including attention, sleep, and memory. Cortical networks are constantly alternating between different dynamic states to accommodate the large rhythmic patterns underlying the diverse cognitive functions administrated by the cortex. However, the full extent of the functional structure of these networks, especially the interactions with astrocytic networks is poorly understood. It has been postulated that at least ten distinct mechanisms are required to cover the wide frequency range of neural oscillations, however, the mechanisms that gear the transition between distinct oscillatory frequencies are unknown. In this study, we aim to discover the involvement of astrocytes, the prevailing subtype of glia in the brain, in modulating network activity. Specifically, we focus on astrocytic K+ clearance processes in modulating neural oscillations at both network and cellular levels. Since astrocytes are central for maintaining K+homeostasis, our study suggests that modulation of their inherent capabilities to clear K+ from the extracellular milieu is a potential mechanism to optimize neural resonance behaviour and thus tune neural oscillations.
