Hanukkah
A rake for photonic fields
Sending information from photoreceptors through ganglion cells to neural cortex can be imagined looking a Hanukkah candle stick.
What are ganglion cells?
Imagine a photoreceptor as a Hanukkah, where each level of candles can rotate around the center pole. As a stream of photons is passing through, it will create impact with each candle and create a momentum that will turn each level a certain angle at each moment of time.
How does a stream of photos look like?
If a stream of photons representing smooth gradient or flat filed is passing though arms at all levels would be rotated at the same angle. while for more complex structures and junctions and textures there would be complex disparity in the angular distribution between the levels.
In computer vision the Hanukkah candle stick can be represented by a convolutional tree or a decomposition of image into a multiscale image pyramid.
As we drive our attention through the visual field the pulls are created sending the information to the brain. The strength of the pull is dictated by distribution of angles at each level of candle stick. The more smooth the distribution is, the weaker is the strength of the pull.
Later the cortex decodes spatial frequency based on the strength of the signal. Weaker signal corresponding to low frequency is absorbed in the deeper layers of the cortex, while stronger signal is distributed along the top layers of the cortex.
