 This paper proposes a new approach to modulating hippocampal gamma power by using a linear quadratic integrator, LQI, servocontroller. This controller is designed to adjust stimulation parameters according to changes in gamma power, allowing for more precise control over the amplitude and frequency of stimulation. The authors tested their proposed system in a simulated environment and found that it successfully controlled gamma power in 15 out of 17 subjects. They also demonstrated that the stimulation threshold could be set at levels that were both physiologically safe and within the range of frequencies that are relevant for clinical applications. Finally, they compared their results to other closed lubed neuromodulation strategies and discussed potential future experiments. This article was authored by Carlos Idavela, David X.
