Perineuronal nets in subcortical auditory nuclei of four rodent species with differing hearing ranges.

Perineuronal nets (PNs) are aggregates of extracellular matrix molecules that surround some neurons in the brain. While PNs occur widely across many cortical areas, subcortical PNs are especially associated with motor and auditory systems. The…

Bilateral projections to the thalamus from individual neurons in the inferior colliculus.
