A compact electroencephalogram recording device with integrated audio stimulation system

A compact electroencephalogram recording device with integrated audio stimulation system.

A compact (96 x 128 x 32 mm(3), 374 g), battery-powered, eight-channel electroencephalogram recording device with an integrated audio stimulation system and a wireless interface is presented. The recording device is capable of producing high-quality data, while the operating time is also reasonable for evoked potential studies. The effective measurement resolution is about 4 nV at 200 Hz sample...

Low Delay Audio Streaming for a 3D Audio Recording System

This paper presents a prototype of a 3D audio recording system named AudioSense which uses Wireless Acoustic Sensors to capture spatial audio. The sound is recorded in real-time by microphones embedded in each sensor device and streamed to a Processing Unit for 3D audio compression. One of the key problems in systems which stream audio data is end-to-end latency. This paper is focused on analyz...

Integrated device for optical stimulation and spatiotemporal electrical recording of neural activity

Neural stimulation with high spatial and temporal precision is desirable both for studying the real-time dynamics of neural networks and for prospective clinical treatment of neurological diseases. Optical stimulation of genetically targeted neurons expressing the light sensitive channel protein Channelrhodopsin (ChR2) has recently been reported as a means for millisecond temporal control of ne...

Compact, Multi-channel, Electronic Interface for Pns Recording and Stimulation

A multi-channel system for neural signal recording/stimulation is presented. The system is split on two devices: an implantable High Voltage (HV) CMOS integrated circuit (IC) hosting a sigma delta modulator, together with a low noise preamplifier/prefilter and a digital platform for sigma delta decimation/control implemented on a FPGA. This innovative approach guarantees a robust communication ...
