AfterRecording

ALL the material used during the experiment (electrodes, EEG cap, MEG helmet, MEG chair) MUST be cleaned at the end of the recordings by following the instructions below. It is FUNDAMENTAL that you dedicate some time (usually no more than half an hour) and attention to this last step, otherwise you will harm your colleagues and the lab's equipment.

Cleaning of the electrodes

Brush each electrode with the toothbrush in water with a little soap in order to remove all the conductive paste. Wrap each electrode separately and let them dry on a paper towel on the table in the consultation room.

Cleaning of the HPI coils

Remove the scotch tape, wrap the HPI coils and store them on the table in the consultation room.

Cleaning of the EEG cap

Soak the EEG cap in the EEG bucket (you will find it in the consultation room) with hot (not too hot!) water with soap (in the toilet or in the kitchen) for about 20 min. Then, delicately wash the EEG cap under flowing water and remove the conductive gel from EACH electrode, by using *very gently* the toothbrush if needed.

This step requires CAREFULNESS:

If there is no other MEG/EEG recording the same day, mop up most of the water and put the EEG cap on the polystyrene head in the consultation room.

If there is another MEG/EEG recording the same day, you have to dry the EEG cap with the hairdryer. Since the hairdryer might damage the EEG cap, it is better to let the EEG cap dry naturally and do this step as late as possible.

Cleaning and disinfection of the MEG helmet and MEG chair

Spray the disinfectant solution (you will find it on the table on the left of the computers in the MEG room) inside the MEG helmet and on the MEG chair and wipe the helmet and chair with a paper towel.

Don't forget to remove the eartips from the plastic tubes if you used them for your recording.
