We present a neural recording and spectral analysis RECORDING ANALYSIS integrated microsystem. It is the instrumentational and computa- INTERACE PROCESSOR tional core of an envisioned miniature implantable brain implant for automated epileptic seizure therapy. The microsystem com- WAVELET bines two functional blocks: the neural recording interface and TRANSFORM the spectral analysis processor. The neural interface contains 256 signal acquisition channels recording neural field potentials from an array of 16x 16 electrodes simultaneously, in a distributed \ fashion. The spectral analysis processor computes a wavelet- VIN / based time-frequency map (spectrogram) of the neural recording. _/_/ We demonstrate the functionality of the integrated microsystem in real-time epileptic seizure monitoring and spectral analysis, -- as necessary for subsequent automated seizure prediction and V prevention.
