I found an article that stated:
- "Researchers think neurogenesis helps the brain distinguish between two very similar objects or events, a phenomenon called pattern separation. According to one hypothesis, new neurons’ excitability in response to novel objects diminishes the response of established neurons in the dentate gyrus to incoming stimuli, helping to create a separate circuit for the new, but similar, memory."
What do they mean by "diminish the response of established neuron"? How does it work? Also, what do they mean by "helping to create a separate circuit for the new, but similar, memory"? What is the new circuit and how is it being formed?
