A recent survey of 312 neuroscientists reveals a significant belief that memories may persist in the structure of deceased brains, with 70.7% agreeing on this potential. Roughly 40% foresee the ability to extract these memories in the future. The researchers outlined a tentative timeline, predicting the extraction of memories from roundworms by 2045, from lab mice by 2065, and from humans by 2125. However, challenges remain, including a lack of consensus on memory storage and the necessity for advanced technology, such as AI, to aid these efforts, along with the ethical implications of this work.
One major roadblock: there isn't yet a consensus on exactly how memories are stored. Zeleznikow-Johnston told IFL Science he thinks preserving the brain's connectome, which are neural pathways, would probably be the key to preserving, extracting and recalling memories from the dead.
That's a substantial chunk of neuroscientists who think there's a very real chance that it will work, and my guess is that actually that number will creep up over time as we get better at doing these brain implants, emulations, all these other things.
