In this study, the scientists simulated the process of spaced learning by examining two types of non-brain human cells — one from nerve tissue and one from kidney tissue — in a laboratory setting.
These cells were exposed to varying patterns of chemical signals, akin to the exposure of brain cells to neurotransmitter patterns when we learn new information.
The intriguing part? These non-brain cells also switched on a “memory gene” – the same gene that brain cells activate when they detect information patterns and reorganize their connections to form memories.
Isn’t the title misleading? A cell switching on the same gen neurons use to connect, if exposed to substance used to transmit information, doesn’t mean it stores or transmits any memories. It seems it doesn’t even do anything more, like forming dendrites or “answering” chemically.
Guess that’s just a side-effect of how the gen is exposed.
It’s more than that. People who have had heart transplants can inherit memories and personality traits from the donor. Cells remember more than they let on and can pass these memories to the recipient.
See this study. I think it’s safe to say we have some empirical evidence for this. In the linked study, there’s a kid who received a heart from another kid who died trying to retrieve a power ranger and somehow the donor knew that without anyone telling him. Another kid received a heart from a kid who drowned and he became afraid of water.
