I am a hosting a Philosophy Club and this Saturday we are discussing Memory from a psychological and neurological perspective. I am preparing slides and taking notes. I want to thank you for uploading this invaluable course for free. This has benefitted me so so much. May God bless you!
Human brain has 86 billion neurons. But out of that only 1 billion neurons store memories and rest of the 85 billion neurons process that memories. Sir, is it true?
I'm not sure where you are getting that information but it's not an easy question to answer. We know that there are regions of the brain such as the hippocampus that are crucial for memory because we know what happens to people that don't have one. They are no longer able to form long term memories anymore. This structure is very small relative to the rest of the brain but I think it would be a mistake to say that it was the only thing "storing'" memories. Memory storage is still very poorly understood and what we have noticed in studies is actually a reinstatement of activity all over the cortex when we retrieve a memory. These are usually the same neurons that were active during the event that happened. "Processing" of the memories is also poorly understood. There is a network called the default mode network that is active when we are retrieving and thinking about our memories that involves parts of the frontal cortex and other regions but I wouldn't say that the "rest" of the neurons are processing memories. It's a really complicated flow of information and there's still a lot of research that needs to be done before we can say we truly understand what "storage" and "processing" are. I hope that makes sense!
