Abstract

The ultrastructure of synapses three hours after formation of long-term potentiation (LTP) was examined in the local microslices of visual cortical brain slices of 18-20d rats. Slices without potentiating stimulation which were similarly incubated served as controls.

Key words: long term potentiation (LTP);Visual cortical brain slice;Synaptic cleft;Postsynaptic densities(PSD);The curvature of the synaptic interface spine synapse;Perforated synapse;
