About The Cover

Cholecystokinin (CCK)-containing neurons of the normal rat hippocampus illustrated by dark-field microscopy after immunocytochemical staining. These CCK-containing interneurons are a subset of -aminobutyric acid—containing interneurons that are resistant to epileptic seizure activity (magnification, ·400). See page 73. [Robert S.
