Effect of Associative Learning on Memory Spine Formation in Mouse Barrel Cortex
Table 1
Statistically significant effects of conditioning and pseudoconditioning on dendritic spines in the barrel cortex.
ā
Single-synapse spines
Double-synapse spines
Effects after conditioning
Decrease in the number of thin spines
Increase in the number of sER-free and SA-containing spines Increase in inhibitory PSD area in sER- and SA-containing spines Increase in the number of polyribosomes in SA-containing spines
Effects after conditioning and pseudoconditioning
Increase in the number of polyribosomes in sER-free spines Decrease in the number of polyribosomes in sER-containing spines Increase in the number of mushroom spines Decrease in the number of stubby spines
ā
Effects after pseudoconditioning only
Increase in the number of sER-free spines
Increase in the number of polyribosomes in sER-free spines
