Mutations in presenilin (PS) proteins cause familial Alzheimer’s disease. We herein tested the hypothesis that the expression levels of PS proteins are differentially affected during healthy aging, in the absence of pathological mutations. We used a preclinical model for aging to identify associations between PS expression and quantitative behavioral parameters for spatial memory and learning and...
Neurons expand, sustain or prune their dendritic trees during ontogenesis [Cline, H.T. (2001). Dendritic arbor development and synaptogenesis. Curr. Opin. Neurobiol. 11, 118–126; Wong, W.T. and Wong, R.O.L. (2000) Rapid dendritic movements during synapse formation and rearrangement. Curr. Opin. Neurobiol. 10, 118–124] which critically depends on neuronal activity [Wong, W.T., Faulkner-Jones, B.E.,...
