Sequence of abnormal dendritic spine development in primary somatosensory cortex of a mouse model of the fragile X mental retardation syndrome.

Abstract excerpt

Anatomical analyses of occipital and temporal cortex of patients with fragile X mental retardation syndrome (FXS) and in a mouse model of the syndrome (FraX mice) compared to controls have suggested that the fragile X mental retardation protein (FMRP) is important for normal spine structural maturation and pruning. However, a recent analysis of spine properties in somatosensory cortex of young FraX mice has...
