“The common language of neuromorphic chips is the address-event representation
(AER) communication protocol, which uses time-multiplexing to emulate extensive
connectivity between neurons.

On Synthetic AER Generation
“The number of time slots depends on the time assigned to a frame (for example T frame =
40ms) and the time required to transmit a single event (for example T pulse = 10ns)….The
system has been implemented using VHDL …It can read or write an AER event every
T pulse = 40ns. If T frame = 40ms, then this implies N x M x K ≤ T frame /T pulse = 10 6 .”

The retina as a two-dimensional detector array
in the context of color vision theories and signal
detection theory
“The Young-Helmholtz hypothesis of three color mechanisms has served as the basis
for literally all color theories and is essentially the foundation for all geometrical color
theories. Another important contribution that enhanced the development of color
research were the Grassman Laws, which stated the commutative and associative
properties of color mixing in simple mathematical terms. The geometrical color theories
developed around the idea that if there exist three different color mechanisms in the eye,
and if color mixtures obey certain linear mathematical rules, then color space can be
described by a three-dimensional simple geometrical space.”[93]

Computer Graphics
“Ewald Hering first advocated the opponent process theory of color in the 1870s. It
departed from the prevalent theory of the time, the trichromatic theory of Thomas
