TL;DR: This system is used to record spatial properties of cat brain activity in vivo, including sleep spindles, single-trial visual evoked responses and electrographic seizures, and it is found that seizures may manifest as recurrent spiral waves that propagate in the neocortex.
Journal ArticleDOI
Tilted Pillars on Wrinkled Elastomers as a Reversibly Tunable Optical Window
TL;DR: The design and fabrication of tilted micropillar arrays on wrinkled elastomeric poly(dimethylsiloxane) as a reversibly switchable optical window is demonstrated and is fully reversible and repeatable for many cycles.
Journal ArticleDOI
A Fully Integrated Wireless Compressed Sensing Neural Signal Acquisition System for Chronic Recording and Brain Machine Interface
Xilin Liu,Milin Zhang,Tao Xiong,Andrew G. Richardson,Timothy H. Lucas,Peter S. Chin,Ralph Etienne-Cummings,Trac D. Tran,Jan Van der Spiegel +8 more
TL;DR: An optimized wireless compressed sensing neural signal recording system that achieves high signal recording quality with minimized power consumption, while reducing the risk of infection from through-skin connectors has been successfully used for long-term wireless neural recording in freely behaving rhesus monkey.
Journal ArticleDOI
In-memory Learning with Analog Resistive Switching Memory: A Review and Perspective
Yue Xi,Bin Gao,Jianshi Tang,An Chen,Meng-Fan Chang,Xiaobo Sharon Hu,Jan Van der Spiegel,He Qian,Huaqiang Wu +8 more
TL;DR: This article defines the main figures of merit (FoMs) of analog RSM hardware including the basic device characteristics, hardware algorithms, and the corresponding mapping methods for device arrays, as well as the architecture and circuit design considerations for neural networks.
An Overview of Sigma-Delta Converters: How a 1-bit ADC achieves more than 16-bit resolution
TL;DR: The technique of oversampling is looked at, which can be used to improve the resolution of classical A/D methods and how sigma-delta converters use the technique of noise shaping in addition to oversampled to allow high resolution conversion of relatively low bandwidth signals.
