Recording Brain Signals from Freely Moving Piglets

Begin with an awake piglet wrapped in a towel for comfort.

Clean the piglet's head.

Use an appropriate tool to remove dead skin cells, then cleanse the area.

To record brain signals, attach a ground electrode over the cerebellum and a reference electrode on the nose.

Place the recording electrode at the desired location on the brain.

Connect the electrodes to the telemetry unit, which wirelessly transmits data from the electrodes to the receiver for monitoring.

Activate the telemetry unit.

Cover the telemetry unit and electrodes with silicone rubber and allow it to solidify.

Let the piglet acclimate and display normal behavior.

Record brain signals from the active piglet.

After recording, carefully recapture the piglet.

Remove the silicone patch containing the embedded electrodes and telemetry unit, and return the piglet to the pigpen.

Mark the piglet with a number as necessary, and wrap the animal in a towel to calm it down. Holding the piglet with one hand at the body or forearm, and using the other hand to control the snout, have an assistant clean the animal's skin using an appropriate tool to remove any dead skin as necessary.

Place the recording electrodes at the appropriate
