The Rat Spinal Cord Image Archive (SCIA) is an image library of spinal cord motoneurons for analyzing sex differences and effects of prenatal antiandrogens on these neurons.


The Rat SCIA package includes a library of images taken through a microscope featuring spinal cord motoneurons that are different between males and females.  Some of the males and some of the females were treated with an anti-androgen drug during prenatal development, which had a dramatic impact.  Also included is a PDF of an article explaining the use of the images, a spreadsheet denoting the sex and treatment group of each individual, calibration files, PowerPoint slides, and sundry other resources that faculty might find useful (e.g. links to free image analysis tools).
