Gamma frequency entrainment attenuates amyloid load and modifies microglia
… driving FS-PV-interneurons at gamma frequency (40 Hz) reduced levels of amyloid-[beta] (A[beta])₁-₄₀ and A[beta] ₁-₄₂ isoforms in the hippocampus of 5XFAD mice. Neither driving FS-PV-interneurons at other frequencies, nor driving excitatory neurons, reduced A[beta] levels. …

Automated cell-targeted electrophysiology in vivo and non-invasive gamma frequency entrainment
Targeted patch clamp recording is a powerful method for characterizing visually identified cells in intact neural circuits, but it requires skill to perform. We found that a closed-loop real-time imaging strategy, which continuously compensates for cell movement while approaching the cell with a …

Synchronization in Coupled Opto-thermal Silicon MEMS Limit Cycle Oscillators
… cycle oscillations, self-synchronization, and frequency entrainment to an external drive. In this work, we chart the behavior of silicon MEMS oscillators that are nominally 40 µm long and 205 nm thick, mechanically coupled, and opto-thermally driven by a continuous-wave helium-neon laser. …

Identification of Thermoacoustic Dynamics Exhibiting Limit Cycle Behavior
… the nonlinearity is developed which uses frequency entrainment to offer sufficient information for the identification. Its validity is assessed on a model, which is based on known dynamics of the thermoacoustic system. The structure of the identification algorithm is based on a two-mode …

Advanced intelligent control and optimization for cardiac pacemaker systems
… Thus, this work develops a new method based on frequency entrainment to analyze pole-zero characteristics of the phase error between abnormal ECG and entrained Yanagihara, Noma, and Irisawa (YNI)-response. The thresholds of poles and zeros to diagnose deadly bradycardia and tachycardia are …
