The synchronous and periodically fluctuating balance between excitatory and inhibitory circuits of connected neuronal populations manifests as neural oscillations [1–3]. These rhythmic waves of brain activity drive multiple physiological and behavioral processes in the sensory, motor, and cognitive domains [4–9]. Further, abnormal oscillatory patterns have been observed in psychiatric and neurological disorders [10–14]. Thus, there is an increasing interest in developing tools to externally control neural oscillations for research and therapy.
