The Cellular Context Of Estradiol Regulation In The Zebra Finch Auditory Forebrain, Maaya Ikeda Nov 2016

The Cellular Context Of Estradiol Regulation In The Zebra Finch Auditory Forebrain, Maaya Ikeda

Doctoral Dissertations

Estradiol, traditionally known as a hormone that communicates with distant cells in the body, is also synthesized locally in the brain to act as a neuromodulator. Neuromodulators differ from neurotransmitters in that they simultaneously affect a population of neurons and their actions are not limited to the synapse. One of the many effects of estradiol signaling is rapid modulation of auditory processing in response to external stimuli. The enzyme required for estradiol synthesis, aromatase, is highly expressed in the regions that are involved in higher-order processing of sounds in humans and songbirds. Since zebra finches, a type of songbird, are …


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 …
