摘要

提出了一种监测大脑不同深度的无线记录系统。16通道录音系统包括低噪声放大器、模拟多路复用器、模拟数字转换器、蓝牙模块和信息集线器。神经信号是时分复用的，并由板载8位模拟数字转换器采样，每通道采样率高达12k /s，总电压增益为5000 V/V。每个通道由GUI控制，以适应不同类型的神经信号，这些信号可以在PC机上独立观察。我们已经证明，该板可以提供一个有用的测量老鼠的神经信号在体内。对记录的信号进行快速傅里叶变换，进一步分析记录的神经信号活动。

An integrated system for brain machine interface

A wireless recording system for monitoring the different depth of brain is proposed. The 16-channel recording system includes low-noise amplifiers, analog multiplexers, analog to digital converters, Bluetooth module and an information hub. Neural signals are time-division multiplexed and sampled by an on-board 8-bit analog to digital converter at up to 12k sample/s per channel and overall voltage gain is 5000 V/V. Each channel is controlled by a GUI to fit different kinds of neural signals, which can be observed independently in a PC. We have demonstrated that the board could provide a useful measurement of a rat's neural signals in vivo. The recorded signals can be further processed by the fast Fourier transform to analyze the recorded neural signal activity.
