What are the implications with respect to amount of information storage capacity in a typical human brain? If this type of impressive autobiographical recall is both semantic and sensory-perceptual then this must be many terabytes of data packed away safely in synapses. I’m was pretty sure I could be socked away a a virtual system given a few gigabytes. Now I am not so sure. Not being able to recall long term memories does not mean that those memory traces/engrams are not embedded somewhere permanently in synaptic circuits and being used for processing in ways other than “mere” recall.
