Computerized body temperature telemetry in small animals: use of simple equipment and advanced noise suppression.

Telemetric measurement of body temperatures in small animals implanted with commercially available transmitters (Mini-Mitter) has been automated using the Commodore C-64 microcomputer. Transmitter output frequencies are received by common AM-radios, converted to TTL level by a simple interface and measured by a machine language subroutine. Multiplexed input is under software control and allows for the recording of at least 16 animals selectively, with data points for each sample every 3 min. The effects of environmental electrical noise are significantly reduced by an error detection system based on the separate reception of interference.

Sleep telemetry in the rat. II. Automatic identification and recording of vigilance states.

An identification system for the vigilance states of the rat is described which uses as inputs the cortical EEG, neck muscle EMG and motor activity, and which allows concomitant monitoring of feeding and drinking behaviour. State identification and data recording are performed in an on-line and an off-line stage which are designed to accommodate a large number of data for computer processing.

Monitoring of the neonatal electroencephalogram using an infrared multichannel telemetry system.

A 3-channel neonatal medical monitoring system is described which uses infrared light instead of electrical leads to transmit physiological signals from the neonate to monitoring equipment. This system is especially applicable to situations where low level physiological signals such as the EEG need to be monitored in the vicinity of other life support and monitoring equipment that is likely to introduce electrical interference. Examples of EEG activity showing the progress of a neonate, who had experienced asphyxia, are presented.

Video EEG telemetry using an ambulatory EEG cassette recorder.

A system of video/EEG monitoring is described which is complementary to out-patient ambulatory EEG recording and prolonged hospital admission for intensive assessment. An ambulatory EEG cassette recorder is incorporated in the system which increases the usefulness of this equipment. In addition all the recorded EEG may be rapidly reviewed. This system has proved valuable in the management of selected patients seen in a special clinic for epilepsy.
