Feb, 2002  |  Pubmed ID: 11876787 N-methyl-D-aspartate (NMDA) receptors mediate long-term changes in excitatory synapses in response to glutamate release. In the cerebellar granular layer, most glutamatergic synapses are formed between mossy terminals and granule cell dendrites, which together with some other components, make up complex glomerular structures. Glomeruli contain numerous attachment plaques (or puncta adherentia), which are sites of adhesion between cells. These structures are found mainly between granule cell dendrites, and probably help maintain the integrity of glomeruli. Attachment plaques contain adhesive…
