title: Dendro-dendritic pentalaminar junctions in the Weaver mouse cerebellum.
abstract: The cerebellum of weaver mouse is characterized by an extensive reorganization of cell interaction secondary to the absence of mature granule cells. One yet undescribed modality of reorganization found in the hemispheres of 1-month-old animals consisted in the presence of dendro-dendritic pentalaminar junctions. The possible formation of these junctions by fusion of facing post-synaptic densities is discussed.
