Electrical responses of astrocytic glia from the mammalian central nervous system cultivatedin vitro (original) (raw)

Zusammenfassung

Einzelne Astrozyten in Gewebekulturen vom Klein-und Mittelhirn junger Katzen wurden elektrophysiologisch untersucht. Ableitungen mit Mikroelektroden, die unter mikroskopischer Kontrolle in die Gliazellen eingestochen waren, zeigten Ruhepotentiale ähnlich den aus Nerven- und Muskelfasern bekannten. Durch isolierte Umspülung der Gliazellen mit isotonischer KCl-Lösung konnten diese Ruhepotentiale aufgehoben werden. Elektrische Reizung der Gliazellen verursachte eine temporäre Reduktion des Ruhepotentials für 4–5 s. Es werden Angaben gemacht über die Reaktion der Gliazellen nach Kokainisierung und nach Urethannarkose.
