The EEG correlates of episodic recall and semantic memory imply two separate though interacting systems. These two systems each have their own characteristic operational frequencies, with one being fronto-limbic, and theta based, and the other one parietally based in the alpha band. Work from Wolfgang Klimesch's lab in Salzburg Austria has documented the phasic frontal midline theta associated with memory activation and retrieval, as well as documenting the nature of the semantic memory and the effect of the individual alpha frequency (IAF) "tuning" on sematic recall. The slower the alpha frequency (IAF), the worse the semantic memory performance

Recent neurofeedback studies by Simon Hanselmayr showing improvement of memory with the re-tuning of the alpha frequencies is powerful evidence of a causal link between the alpha frequencies and semantic memory performance. These findings have important implications for brain brightening in the ever aging population, especially in light of the correlation between slower alpha frequencies and aging, and the associated memory decline.

The phase locking of alpha and theta, and the interaction of these two separate systems is thought to be at the neurophysiological basis of the event related potential (ERP), and is one of the basic tennents of the model of consciousness being taught currently.

Underlying all this memory processing is the basis of the memory storage. Sensory information has been shown to be encoded as a Gabor function using indwelling microelectrode recordings. This points directly to an "interference pattern" based encoding and retrieval system, or the "holographic" nature to memory storage.

There are implications for superconductivity and/or superfluidity being required for our memory's proper function, and within this there are implications for a neurophysiological basis to exist underlying archetypal memory, and the mechanisms for communication at an archetypal level.
