Stereotypical changes in the pattern and duration of long-term potentiation at postnatal days 11 and 15 in the rat hippocampus. Cellular specializations that impart stability and flexibility to synaptic function. Synaptogenesis via dendritic filopodia in developing hippocampal area CA1. Slices have more synapses than perfusion-fixed hippocampus from both young and mature rats. Three-Dimensional Relationships between Hippocampal Synapses and Astrocytes J. Neurosci.
Dendrites are more spiny on mature hippocampal neurons when synapses are inactivated.
