title: Large mechanical changes in the bullfrog olfactory bulb evoked by afferent fiber stimulation.
abstract: The isolated olfactory bulb of the bullfrog responds to olfactory nerve stimulation with large mechanical changes in the bulb. The sequence of these changes represents: (1) swelling of the bulb associated with action potential production in the secondary neurons; (2) shrinkage during powerful inhibition of the secondary neurons; and (3) swelling accompanied by repetitive firing of action potentials in the bulb. The effects of bicuculline and Cl-free Ringer on these mechanical changes were examined. The shrinkage of the bulb is closely related with the inhibitory postsynaptic potentials (IPSPs) in the mitral cells.
