(2) Lectin binding and tridimensional reconstruction provided new information on the distribution of olfactory glomeruli and on regional and interspecific differences.
(3) Pathological changes may, thus, be initially confined to projecting and intrinsic neurons localized in cortical and subcortical olfactory structures; arguments are advanced which favor the view that excitotoxic phenomena could be mainly responsible for the overall degenerative picture.
