All they know about memory in the brain is that the brain processes info and stores it. Where, they don't really know. Only that certain areas of the brain process certain info and that certain functions of the brain are in certain areas.
The brain is basically a very complex computer and information retrieval device. It's most likely that memory storage and access/processing is happening at a quantum level in the neurons and glia....within the microtubules and/or at even lower levels of biology. It wouldn't surprise me if consciousness itself is a quantum mechanical process of some kind, or at least works on that level in conjunction with the rest of the brain. Given the way the quantum world works, it might be entirely separate from the brain/body itself. Information doesn't necessarily need a container in order to be encoded. The information itself is the container. Just so long as there is energy, information can be encoded onto it. Even there, the information itself can be the energy needed to carry itself. Bit of a circular process
