Abstract

New evidence is emerging about the dynamics of interaction between circadian rhythms and brain waves, whose coordination occurs through the entrainment process. The so-called “oscillopathies” or dysfunctions in synchronization of neuronal oscillation in key brain networks lead to the onset of neurodegenerative diseases. A typical example of alteration is insomnia, a risk factor for the oscillopathies, increasingly widespread worldwide. Recently, synchronization of circadian rhythms in cell cultures has allowed an improvement in the physiological relevance of responses to stimuli. Furthermore, brain organoids and neurons cultured in microfluidic systems are the latest frontiers for in vitro reproduction of rhythmic electrical signals. In this review, the combination of these in vitro experimental approaches is proposed as suitable for a more direct investigation on the common mechanisms and neurophysiological substrates underlying brain waves and circadian oscillations, and useful to evaluate the effects of “oscillotherapeutic” drugs for personalized neuromedicine.
