NMDA-like receptors in the nervous system of the crab Neohelice granulata: A neuroanatomical description
N-Methyl-D-aspartate receptors (NMDARs) are involved in learning and memory processes in vertebrates and invertebrates. In Neohelice granulata, NMDARs are involved in the storage of associative memories (see references in text). The aim of this work was to characterize this type of glutamate recepto...
