Presynaptic Ultrastructural Plasticity Along CA3→CA1 Axons During Long-Term Potentiation in Mature Hippocampus

ABSTRACT In area CA1 of the mature hippocampus, synaptogenesis occurs within 30 minutes after the induction of long‐term potentiation (LTP); however, by 2 hours many small dendritic spines are lost, and those remaining have larger synapses. Little is known, however, about associated changes in presy...
