C. Transgenic mice that express the CaMKII-Asp286 kinase and receive doxycycline perform as well as wild-type mice in learning the Barnes maze task (approximately 65% of animals learn the task), whereas transgenic mice without the doxycycline (in which the kinase is highly expressed) do not learn the task.
