Download or read book Wireless Multichannel Microsystems for Time Share Chemical and Electrical Neural Recording written by Masoud Roham and published by . This book was released on 2010 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project has developed single-chip wireless microsystems fabricated using a 0.5-μm double-poly triple-metal n-well CMOS process that incorporate three powerful neuromonitoring techniques: fast-scan cyclic voltammetry (FSCV) for monitoring neurotransmitter concentrations, extracellular electrophysiology for single-unit recording, and time-share recordings of these two techniques for quasi-simultaneous measurements of chemical and electrical neural activity at a single brain site in vivo. These devices also support electrical stimulation for focal activation of neural circuits. In particular, a 1.1-mW, 5-mm2, 4-channel integrated circuit has been developed that can be dynamically configured to perform neurochemical monitoring using 300-V/s FSCV and neuroelectrical recording using extracellular electrophysiology. The chip architecture uses a 76-μW, 3rd-order, continuous-time delta-sigma modulator per channel that achieves an rms input-referred noise of 56.7 pA (dc-5 kHz) and 3.5 μV (1.1-5 kHz) for chemical and electrical neuromonitoring, respectively. The chip architecture also incorporates monolithic circuitry for generating FSCV and biphasic constant-current stimulus waveforms. It has been externally interfaced with carbon-fiber microelectrodes implanted acutely in the caudate-putamen of an anesthetized rat, and enables chemically resolved monitoring of electrically evoked dopamine release and its postsynaptic bioelectrical response at the same recording site. The dopamine limit of detection corresponding to a signal-to-rms noise ratio of three is estimated to be 16.7 nM, which compares favorably with the amplitude of phasic dopamine transients that varies in the range of 40 nM-1 μM. The chip has also been packaged on a miniature rigid-flex substrate to develop an implantable device for investigating brain-behavior relationships in an ambulatory rat. The device successfully captures the effect of high-dose amphetamine administration on electrically and non-electrically evoked dopamine neurotransmission in the brain, demonstrating that the technology developed throughout the course of this project can indeed be applied to conduct neurochemical measurements in the context of behavior.

Download or read book Energy Efficient Integrated Biomedical Circuits and Systems for Unobtrusive Neural Recording and Wireless Body Area Networks written by Chul Kim and published by . This book was released on 2017 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite tremendous progress over the years, current brain-machine interface (BMI) systems are relatively bulky, highly invasive, and limited in their effectiveness except for highly constrained tasks such as moving a cursor on a computer screen. To improve performance of current BMI systems, it is necessary to dramatically increase spatial resolution and coverage across the brain without constraining the mobility of the subject. This calls for innovative approaches to high-density integrated neural recording and stimulation using non-invasive or minimally invasive microelectrode and custom silicon integrated circuits at extreme energy and area efficiency. In this thesis, I present energy-efficient fully integrated miniaturized implants for electrocortical recording and stimulation, and unobtrusive body-area networks systems for subcutaneous power delivery and data communication, as fundamental building blocks to next generation BMI. First I describe a fully wireless, encapsulated neural interface and acquisition chip (ENIAC) in 180nm silicon-on-insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology for 16-channel neural recording and stimulation including integrated 4x4 electrode array, coil antenna, and wireless power transfer and data telemetry without any external components, completely contained in less than 3mm3 volume suitable for minimally invasive surgical insertion on the cortical surface. A novel fully integrated wireless power receiver design with an RF-decoupled H-tree signal distribution network delivers 1mW power over 1 cm distance while mitigating RF interference in the sensitive analog front-end and acquisition circuits for recording of electrocorticography (ECoG) signals transmitted through the skull. Second I highlight a 1mm2 16-channel neural recording and acquisition system-on-chip in 65nm CMOS offering 92 dB input dynamic range and
