Question

Quizplus · Accepted Answer

Doogie mice have a mutation that causes them to produce an excess of the NR2B subunit of the NMDA receptor, which is typically only produced in high levels during development. This results in improved learning and memory abilities in the mice. Therefore, they produce NR2B into adulthood, not NR2A, and do not have more difficulty in learning tasks such as the Morris water maze or stimulus discrimination tasks.
