Description
Emma Shaughnessy, Benjamin Horne, and Kim Huhman map, in a 2024 study, perineuronal nets in the Syrian hamster brain for the first time. These nets are mesh like coatings of matrix proteins around certain neurons. They are suspected players in stress related mental illnesses, from schizophrenia to depression and anxiety.
Syrian hamsters are a favored model for social stress and daily rhythms, yet their nets were uncharted. The team found nets throughout the cortex and hippocampus. In deeper regions like the hypothalamus and striatum, where rats and mice show them, hamsters had few or none. Social stress changed the nets in one hippocampal area, and the change differed by sex. Day versus night sampling found no daily swing where they looked. A baseline atlas like this must exist before anyone can claim stress moves these structures in this species.
