Do you think memories are A.stored in a specific part of the brain B holographically stored in brain C nonlocally accessed by brain D other?

While we don't know where memories are stored, we do know that certain areas of our brain are responsible for recording, archiving, and retrieving them. The where's and the how's of our memories are encoded in a nervous system and its one of the most challenging questions in biological research

Due to Alzheimer's A is the closest, but it is not wholly specific. Memories are more like neural networks in which synapses lock with other synapses linked to the memory.

I don't have an firm opinion, but A looks increasingly unlikely
