Abstract

A simple miniature telemetry system for neural recording from freely moving rats is described. It weighs only 1% of the body weight of an adult rat and its recordings are devoid of artifacts due to the animal movement. Together with its long recording time (more than 38 h), its isotropic nature, which is essential for working with freely moving animals, offers further advantages. A frequency-modulation receiver with a flat frequency response down to 6 Hz has been designed for wide-spectrum recording of neural signals, allowing field potential recordings. A detailed printed-circuit layout and the lack of a trimming requirement will allow the system to be easily duplicated by other neuroscientists who are not familiar with wireless-transmission technologies.

摘要

本文描述了一种用于对自由活动大鼠进行神经记录的简单微型遥测系统。它的重量仅为成年大鼠体重的1%，并且其记录不会因动物移动而产生伪迹。连同其较长的记录时间（超过38小时），其各向同性特性（这对于研究自由活动动物至关重要）还具有其他优势。已设计出一种频率调制接收器，其频率响应平坦，低至6Hz，用于神经信号的广谱记录，从而实现场电位记录。详细的印刷电路布局以及无需微调的特点，将使该系统能够被其他不熟悉无线传输技术的神经科学家轻松复制。
