We studied physiological properties of glial cells from acute slices of biopsies from patients
operated for intractable mesio-temporal lobe epilepsy using whole-cell patch-clamp
recordings. Cells were filled with Lucifer Yellow (LY) during recordings to allow
morphological reconstruction and immunohistochemical cell identification. Seizure-
associated astrocytes had complex, arborized, highly branched processes giving them a
stellate appearance, and cells stained intensely for the intermediate filament GFAP as …
