telemetry in small animals

emka TECHNOLOGIES offers three solutions for telemetry studies in small animals such as mice, rats and rabbits:

• rodentPACK telemetry
• Telemetry Research implant telemetry
• software suite compatible with your DSI telemetry

Subjects are conscious and freely moving in the three cases.

rodentPACK

rodentPACK is a cost-effective solution for running telemetry studies in animals 250g and upwards. Applications are varied, e.g. sleep and epilepsy studies, ecg recording.

During surgery, biopotential electrodes are implanted and a connector is mounted on the skull. Once the head connector is secure, the rodentPACK transmitter can be connected and disconnected as necessary for each recording session.

Upto 8 signals are acquired from each animal: 

• 2 eeg signals 
• 2 emg/ecg signals (any combination) 
• 3-axis acceleration (for postural information)
• total acceleration.

Telemetry Research implants

Implants from Telemetry Research can be used in animals 200 g and upwards. Several transmitter implants are available for acquiring different parameters such as biopotentials, pressure and temperature. Of note, implants are available for the acquisition of sympathetic nerve activity with a sampling rate of 8 kHz. 

In this system, customers recharge the transmitter batteries themselves.  The recharging device is a flat platform on which the animal cage can be placed. This makes it possible to obtain a lifetime recording!

The telemetry hardware is open so you can use any software to acquire your data. 

DSI  implants

Data Sciences International (DSI) offers a wide range of transmitter implants for the measurement of different parameters such as biopotentials, pressure and temperature.

iox may be used for acquisition from DSI implants - this is is possible because of the openART software interface. The analysis files can subsequently be analyzed in ecgAUTO.

Long-term studies with implanted animals are used to study: 

• the long-term effects of a pharmacological product
• cardiovascular remodelling following surgical intervention 
• the development of pathologies in transgenic mice (or other animals)
• etc

example of use

Implanted rodents are used by the cardiovascular phenotyping laboratory of the Montreal Heart Institute. Their setup includes: 

• mice equipped with 16 ecg implants and 8 bp implants
• rats equipped with 8 ecg implants, 8 bp implants, and 8 implants measuring ecg and bp
• workstations with iox and ecgAUTO. All ecg intervals and segments are measured at a sampling rate of 1000 Hz
