Cover: A proposed mechanism explaining and unifying neurite morphological abnormalities associated with fmr1MO knockdown (branching, fasciculation and guidance) and MPEP antagonism of mGluR. fmr1 and MEP might regulate calcium signalling pathways and influence neurite morphology through modulation of MAP2 phosphorylation. See Tucker et al., pp. 3446-3458, this issue, for further information.
