Table 2. Subject and sample characteristics of the neurosurgery study participants.

Sample tissues available for each individual varied. Details of analyzed samples are shown. Timing of when peripheral tissues were obtained are listed as “days”. Day 0 is indicative of samples taken the day of surgery, after surgery is completed. For brain samples analyzed, the time (in minutes) between administration of the synthetic glucocorticoid and when the second (post) brain sample was resected was recorded. Abbreviations. GC: glucocorticoid, FCD: focal cortical dysplasia.
