Caption

Picture (a) High-resolution electrophysiological recordings captured during anesthetized and pathological recordings captured during a seizure state over extended time intervals. (b) Diagram illustrating the placement of sensors within a cross-sectoral view of the rat brain, serving as a model. (c) Signals obtained from the amplified sensor (red) exhibit superior signal resolution and magnitude in comparison to signals collected using electrodes (blue). Additionally, a distinct 5-10 Hz oscillatory signal during seizures was successfully detected by the amplified sensor as evident in the time-frequency spectrogram when contrasted with the signal recorded by the implanted electrode (black).
