Electrophysiological and morphological properties of granule cells: patch-clamp recordings of newborn rabbit olfactory bulb slices.
Granule cells were investigated by performing whole-cell patch-clamp recordings from thin slices of the olfactory bulb of newborn rabbits. Granule cells were intracellularly stained with Lucifer Yellow in their intact environment. During current-clamp measurements these neurones were characterized by their lack of action potentials upon depolarization. Evidence for a Ca2+ dependent K+ conductance was found. Two types of outward currents were identified in the whole cell mode during voltage clamp; a non-inactivating K+ current that shared some properties of the delayed rectifier K+ current and a non-inactivating K+ current were recorded. No fast inward current was registrated.
