Sex Difference In Calbindin Cell Number In The Mouse Preoptic Area: Effects Of Neonatal Estradiol And Bax Gene Deletion, Richard F. Gilmore Iii Jan 2011

Sex Difference In Calbindin Cell Number In The Mouse Preoptic Area: Effects Of Neonatal Estradiol And Bax Gene Deletion, Richard F. Gilmore Iii

Masters Theses 1911 - February 2014

The sexually dimorphic nucleus of the preoptic area (SDN-POA) was first discovered in rats and is one of the most famous and best studied sex differences in the field of neuroscience. Though well documented in rats (larger in males than females), this sex difference was only recently able to be observed in mice due to the discovery of the protein calbindin-D28k as a marker. Recent studies have shown a larger, more distinct calbindin-immunoreactive (ir) cell cluster in male mice compared to females. However, the exact location of the cluster and whether the sex difference is one of total cell number …


Examination Of Sexually Dimorphic Cell Death In The Pubertal Mouse Brain, Amanda Holley Jan 2011

Examination Of Sexually Dimorphic Cell Death In The Pubertal Mouse Brain, Amanda Holley

Masters Theses 1911 - February 2014

A period of cell death during a critical period early in life is responsible for causing permanent structural changes to many brain areas, but it is not known whether cell death plays a role in brain organization outside of early postnatal life. Puberty is considered a second sensitive period because the brain is the target organ of gonadal hormones. This study looked at global and regional patterns of cell death during pre-puberty and puberty in the mouse brain. My findings show there is more cell death happening during pre-puberty than during puberty. Cell death does happen during puberty but at …
