A columnar model explaining long-term memory

Abstract

A hologram provides a useful model for explaining the associative memory of the brain. Recent advances in neuroscience emphasize that single neurons can store complex information and that subtle changes in neurons underlie the process of memorization. Experimental results suggest that memory has a localized character. This finding is inconsistent with the characteristics of holographic memory, because this memory has a delocalized, uniform distribution of refractive index in the recorded medium. The recently proposed columnar memory model has a discrete distribution of refractive index. In this study, we first examined the performance of columnar memory and found that it was comparable to holographic memory. Secondly, we showed that this model could explain the above-mentioned experimental results as well as associative memory.

Scatterometry of Slant Incidence to Isolated Scatterers for High-Density Memory

“…6) The memory can be high density as w exp has many levels of multivalued information. 5) Figures 3 and 4 indicate that slant incident light increases the resolution and memory density. Figures 5(c) and 5(d) show that as the incident angle increases, the peaks are spaced more narrowly.…”

“…[1][2][3][4] Instead of turning these convexes on and off, the distance between scatterers can be used to store information, at four times the density of conventional memory devices for the same resolution. 5) We simulated the diffraction pattern of isolated scatterers and estimated the original image. 6) The lens of a Blu-ray device has a Fourier transformation (FT) effect, 1,7) but it is done by calculation here.…”
