What is the main goal of this procedure?
The main goal is to perform multi-electrode array recordings from human epileptic cortical tissue to study seizure mechanisms.
How is the tissue prepared for recording?
The tissue is resected, cleaned, sliced into 400 micron sections, and maintained in controlled conditions.
What are the advantages of using multi-electrode arrays?
They allow non-invasive, simultaneous stimulation and recording from multiple sites in the tissue.
What types of events are recorded?
Both spontaneous interictal activity and evoked ictal-like events are recorded.
How does this research contribute to epilepsy treatment?
It helps understand the cellular mechanisms of seizure propagation and the effects of anti-epileptic drugs.
Who are the key contributors to this research?
The research involves collaboration between neurosurgeons, epileptologists, and postdoctoral researchers.
