The study of the emergence of sleep and waking during embryonic life forms a fundamental part of understanding sleep physiology. Electroencephalography (EEG) is one of the most basic tools used to investigate sleep. We describe the preliminary design of a telemetry system composed of conductive polymer electrodes connected to a transmitter and a receiver. As an additional benefit, the system is electromagnetically compatible with Positron Emission Tomography (PET) scanners, permitting the simultaneous acquisition of PET images and EEG data. The system was developed for recording chicken embryo EEG signals. Electromagnetic interference is avoided using an infrared data link for communication. The system makes use of six conductive polymer electrodes, with dimensions on a micrometer scale, connected via a ZIF (Zero Insertion Force) connector to a small, low power IR transmitter. This transmitter is optically coupled to a receiver, that it is connected to a PC for signal processing and data storage.

Abstract
The study of the emergence of sleep and waking during embryonic life forms a fundamental part of understanding sleep physiology. Electroencephalography (EEG) is one of the most basic tools used to investigate sleep. We describe the preliminary design of a telemetry system composed of conductive polymer electrodes connected to a transmitter and a receiver. As an additional benefit, the system is electromagnetically compatible with Positron Emission Tomography (PET) scanners, permitting the simultaneous acquisition of PET images and EEG data. The system was developed for recording chicken embryo EEG signals. Electromagnetic interference is avoided using an infrared data link for communication. The system makes use of six conductive polymer electrodes, with dimensions on a micrometer scale, connected via a ZIF (Zero Insertion Force) connector to a small, low power IR transmitter.
