Figure 4.

Presynaptic function is not changed in CA1 pyramidal cells from juvenile Cst-1 KO mice. A, Field recordings show that PPF at 50 ms is not altered in Cst-1 KO mice. B, Pooled data for a range of paired-pulse inter stimulation intervals (ISI). C, Short-term synaptic potentiation is not affected in Cst-1 KO mice. D, Pooled data showing pronounced short-term plasticity during the first 3 min after stimulation, which decrease toward baseline after 15 min. E, Dendritic spine density is unchanged in Cst-1 KO mice.
