Sequential changes in the synaptic structural profile following long‐term potentiation in the rat dentate gyrus. II. Induction / early maintenance phase

Long-term potentiation (LTP), one of the most compelling models of learning and memory, has been associated with changes in synaptic morphology. In this study, LTP was induced and animals were sacrificed 1 h after the stimulation of the LTP group (induction / early maintenance phase). Synapses in the directly stimulated middle third of the dentate gyrus molecular layer (MML) were examined while synapses from the inner third of the dentate …
