摘要：

In this paper, we designed a telemetric system to record the electroencephalogram (EEG) from adult freely moving rats. The system has two units: Transmit-end and Receive-end. The Transmit-end is consists of three parts: the preamplifier, which is used instrument amplifier AD620; the LPF (low-pass filter) and the 50 Hz frequency notch filter, which is used the precision amplifier LM324; the transmitter, which is used nRF24E1 chip embedded 8051 core and 8 input ADC transmit the modulated signal at 2.4GHz. The Receive-end is consists of two parts: the receiver, which is used nRF24E1 chip also (nRF24E1 embed RF transmitter and receiver); the interface of Receive-end and PC, which is used MAX3232 (RS-232 chip). The Transmit-end fettered on the back of the rat has light weight (log including battery) and small size (20mmx50mm). The system can measure the EEG signal of the rat in freely moving over a wireless transmission distance of up to 8 m and also can provide a new platform for behavioral and neurophysiological experiments.
