The multilateral analysis of mouse electroencephalography (EEG) is essential for various fields such as neurology, preclinical research, and neural engineering. The systematic and quantitative analysis of visually evoked potential (VEP) elicited by the repeated flash stimuli provides a foundation for related applications. We confirm the experimental validation of the developed mouse EEG sensor through...
A complete neural recording ASIC based on Compressive Sensing (CS) is demonstrated. Implemented using efficient digital circuit, this CS technique is able to achieve 10 times data compression while consuming only 0.83uW (@0.53VDD) additional digital power per electrode. Since CS performance is strongly signal dependent, the ASIC has been tested with standard public database. The characteristic spikes...
Accuracy of realization of capacitance unit by means of the conventional cross capacitor depends on the constancy of end effects of the guard electrodes. The impact of end effects can be reduced by changing the shape and selecting the potential of additional electrodes that are installed on the ends of the guard electrodes.
In the paper we describe a method to extract the topography of an impressed current for our bounded electrical impedance tomography (bEIT) studies. The frequency of the impressed current is low (up to a few hundred Hz), and is buried in background EEG and other noise. For the development of the extraction method, special consideration is given to maximize the signal-to-noise ratio. The standard lock-in...
The prime function of the A.S.T.M. is the development of practical test standards and specifications for commercial use. Pure research is not one of its objectives, but in devising new standards and revising them to keep pace with improvements in the art, much work of a research nature is required. The A.S.T.M. approach is that of the engineer, whose chief concern is evaluation of breakdown in terms...
