Researchers crack part of the neuronal code

Together with colleagues from the Graz University of Technology, scientists from the Max Planck Institute for Brain Research in Frankfurt have succeeded in taking a step towards achieving this. They have shown that early processing stages in the brain gather information over an extended period.

How does the brain store detailed information from sensory stimuli? How much can researchers read from the activity of certain regions of the brain? Current findings confirm a new theory. Up to now, scientists had assumed that the early stages of information processing in the brain took place gradually, that is that one stimulus was processed after another in a conveyor-belt-like sequence. This idea must now be revised. As Danko Nikolic from the Max Planck Institute for Brain Research and his Austrian colleagues Wolfgang Maass and Stefan Häusler have shown, the activity in early brain areas depends on stimuli that arose some time ago. "The brain functions like a jug of water into which stones are thrown and, as a result, generate waves," explains Nikolic. "The waves overlap but the information as to how many stones were thrown into the jug and when they were thrown in is retained in the resulting complex activity patterns of the fluid."

The brain is clearly able to render this information usable and, for example, to superimpose images seen in succession. The duration and intensity of the continuing effect of images that have just been seen corresponds to a very detailed visual memory also known as iconic memory. If you see an image and close your eyes immediately afterwards it remains visible for a short while. It may be located in the primary visual cortex.

At the risk of belaboring the obvious, the foregoing is in clear accord with my own views regarding perception, consciousness & superposition, where the waves being superposed just are photonic waves/state vectors:
