EEG acquisition is performed without the use of tethering cables.
A head connector is implanted in the skull and acts as an interface between the electrodes in the brain and the transmitter. The rodentPACK transmitter may be plugged into and removed from the head connector as required. In this way, the same transmitter is usable on any subject equipped with a connector.
With a transmitter battery powered and equipped with short leads length, rodentPACK provides a high signal-to-noise ratio and permits clean data collection.
The EEG signal is retrieved through surgically implanted electrodes in the cortex, the hippocampus or any other area of the brain. Each signal requires 2 measuring electrodes (positive and negative) and a reference, which is common to all biopotential signals.
Up to 4 bipolar biopotentials can be recorded with rodentPACK. Adjustable settings allow to mix EEG with ECG and/or intramuscular EMG.
