"The findings offer an explanation for why people can’t recall memories from early childhood"

I suppose that those of us who can didn't get the new brain cells.

How far back can most people go?

I remember things from age 4 very clearly....but with the exception of one small memory, its really a fog before that.

I can recall being pushed in my stroller through a gravel parking lot at a restaurant and a conversation between my Mother and a neighbor lady with an infant also in a stroller. When I mentioned it years later, my Mom told me that I was around one year old at the time.

Kind of ironic, devising a Room 101 for rodents...

I remember isolated images from before about the age of 4. I remember events from about age 4 on.

This does make sense, although whether it is borne out in further research remains to be seen. New neurons in the brain would have to plug themselves in to the neurons already in place; that disruption of neural connections could very well disrupt memories.
