Abstract

With the extraordinary navigational ability in large-scale space, homing pigeons have been a valuable model to investigate the neurophysiological substrate of large-scale spatial cognition. Here we show a miniature chronic recording system that can be mounted on the back of freely behaving pigeons. In this paper, we mainly focus on the design and implementation of the headstage comprised of an instrument amplifier with high input impedance and stable gain, which allows multi-unit recording from a pair of electrodes implanted in the brain of pigeons. We also briefly introduce the backpack components and discuss the further optimal design of the system.
用于鸽子和小动物慢性神经记录的微型系统
信鸽具有非凡的大尺度空间导航能力,是研究大尺度空间认知神经生理基础的重要模型。这里我们展示了一个微型的慢性记录系统,它可以安装在行为自由的鸽子背上。在本文中,我们主要关注由高输入阻抗和稳定增益的仪器放大器组成的头级的设计和实现,它允许从一对植入鸽子大脑的电极上进行多单元记录。简要介绍了双肩包的组成,并对系统的进一步优化设计进行了讨论。
