    Abstract:
    The morphology of physiologically identified otolith nerve-activated vestibular neurons was investigated using intracellular injections of horseradish peroxidase (HRP). Eleven utricular, 11 saccular and three utricular/saccular nerve-activated vestibular neurons were labeled with HRP. All of these neurons except one were secondary neurons, the exception being a convergent neuron. The labeled neurons were pyramidal, elongated and ovoidal in shape. Most of the labeled cells were medium to large (mean diameter: > or =30 micro m). There was no apparent correlation between morphology and the different types of otolith nerve-activated vestibular neurons. Thus, it seems likely that the functional type of vestibular neurons cannot be presumed on the basis of their morphology alone.
