Buzsáki's primary interests is "neural syntax", i.e., how segmentation of neural information is organized by the numerous brain rhythms to support cognitive functions.
He identified the cellular-synaptic basis of hippocampal theta, gamma oscillations and sharp waves with associated fast oscillations, their relationship to each other and to behavior and sleep.
He was the first to demonstrate the role of GABAergic interneurons in network oscillations. Buzsáki's recognition of the importance hierarchical organization of brain rhythms of different frequencies and their cross-frequency coupling has opened up opportunities for the dissection of cognitive mechanisms in health and disease.
His most influential work, the two-stage model of memory trace consolidation, demonstrates how the neocortex-mediated information during learning transiently modifies hippocampal networks, followed by reactivation and consolidation of these memory traces during sharp wave-ripple patterns of sleep
