Yesterday I had a MEG (magnetoencephalography) for the first time. In Enduring Epilepsy, I’ve had numerous MRIs and EEGs over the years; but while this was kinda, sorta like both, it was definitely a new experience.
The process of preparing for the MEG takes time. When I arrived the technician measured my head and began hooking me up to leads, just like an EEG. However, there were several more than normal. They were added to my face, around my temples; close to my eyes and ears. Four of the extra electrodes are called coils. They communicate with the machine about how close the head is. The technician took extra time to clean my scalp and ensure each electrode was well-sealed, so it took nearly 2 hours to glue on all the leads.
