Fitness Quote by Robert M. Sapolsky
““It’s not until the non-NMDA has been stimulated over and over by a long train of glutamate release, allowing enough sodium to flow in, that this activates the NMDA receptor. It suddenly responds to all that glutamate, opening its channels, allowing an explosion of excitation. This is the essence of learning.””
About This Quote
Source Speech: Lecture on Neurobiology, 2015
Repeated glutamate stimulation eventually activates NMDA receptors, triggering a burst of neural activity that underlies learning.
In simple terms: Repeated signals unlock learning receptors, causing strong brain activity.
Key Takeaway
Focus on repeated practice to strengthen learning pathways.

Questions to Reflect On
- How does repetition change brain chemistry?
- What limits the speed of learning?
A Different Perspective
If stimulation is too weak or too brief, receptors may not activate, limiting learning.
