"Experience-dependent changes in the structure of dendritic spines may contribute to learning and memory. Encoded by three genes, the Shank family of postsynaptic scaffold proteins are abundant and enriched in the postsynaptic density (PSD) of central excitatory synapses," scientists writing in the Journal of Neuroscience report. "When expressed in cultured hippocampal neurons, Shank promotes the maturation and enlargement of dendritic spines.

Here, we report the phenotype of Shank1 knock-out mice. Shank1 mutants...
