System Configuration

rodentPACK miniature transmitter (5.2g), fixed to the cranium or worn in a jacket, radio-transmits up to 8 physiological signals per subjects:

• 4 biopotential signals (EEG, ECG, EMG)
• 3-axis acceleration, providing postural information
• x/y/z and global acceleration for postural and activity assessment

For EEG acquisition, a head connector is permanently implanted in the skull. This connector is the interface between the electrodes inside the brain and the rodentPACK transmitter, outside the body. The same transmitter is usable on any subject equipped with a connector.

For other signals, the transmitter can also be fixed to the skull connector (with implanted electrodes) or can be worn in a jacket (with external electrodes).

Digital telemetry receivers are positioned in the animals’ room, within 3 to 5 meters distance from their associated transmitters.

Each subject is therefore free to move, single or group-housed in its cage, during the acquisition (up to 32 rats in the same room with no required shielding).

The whole system is compact, as a single receiver can communicate with up to 4 transmitters. Receivers are powered and transmit data through a single Ethernet cable.

With rodentPACK system, we offer a cost-effective system with:

• 150 hours of continuous recording with same batteries
• No refurbishment (batteries cost less than $2/recording)
• Same transmitter usable on any animal equipped with a connector
