Nicotine Receptor (IMAGE) UT Southwestern Medical Center Caption Researchers at the Peter O'Donnell Jr. Brain Institute developed this illustration of the nicotinic receptor based on a structure determined by X-ray crystallography. The ability to grow crystals of the receptor after decades of research is a breakthrough that scientists expect will help them develop new treatments by understanding nicotine's molecular effects.
