The paper quantifies synaptic characteristics in the Etruscan shrew's cortex, finding high synaptic density and similar organization to humans despite significant differences in brain size and synapse number.

This study quantifies 3D synaptic organization in rat CA1 stratum radiatum under normal and cocaine self-administration conditions, finding increased synaptic size and complexity without changes in density.

The paper estimates synapse numbers in the hippocampus and brain-wide using electron microscopy and genetic labeling, finding high densities in isocortex and olfactory areas, and low densities in pallidum and cerebellum.
