Experimental Setup
First step to set up an experiment with the Wireless2100-System is to implant an electrode into the
laboratory animal. The electrode has to be fixed to the skull, for example with dental cement, to
guarantee a stable positioning of the electrode in the desired area of the brain. The electrode connector
must be available on the skin surface of the animal. A ground electrode is essential, a reference electrode
is recommended.
Battery Options
Make sure that the battery of the headstage is charged and plugged in properly. The battery can be fixed
on top of the headstage or it can be stored in a special backpack on the back of the animal. Batteries are
available either with a cable or fixed on a circuit board with a double connector to be plugged in directly
on the headstage, please see the images below.
Use of the Reference and Ground Electrodes
For optimal signal quality in
in vivo
experiments it is necessary to provide a good grounding (GND) and a
well placed reference (REF) electrode. Therefore all headstages of the Wireless2100-System are equipped
with dedicated pins for a ground and a reference electrode.
The reference electrode should be out of a similar or the same material as the recording electrodes and
it should be of comparable size. The reference is ideally placed near the recording electrodes, but not in
active tissue.
The signals from all electrodes are amplified and then each signal from the recording electrodes is
compared to the signal from the reference electrode. The difference is measured by the analog to digital
converter (ADC) and digitized.
