TL;DR: This paper introduces a new technique for the analysis of the chromatic properties of neurones, and applies it to cells in the lateral geniculate nucleus (l.g.n.) of macaque by exploiting the fact that for any cell that combines linearly the signals from cones there is a restricted set of lights that can be exchanged for one another without evoking a response.

TL;DR: The discharges of single neurones in the parvocellular and magnocellular laminae of the macaque's lateral geniculate nucleus were recorded with glass‐insulated tungsten micro‐electrodes and linearity of spatial summation was examined.

TL;DR: For human cortex, the cost of individual spikes is estimated, then, from the known energy consumption of cortex, how many neurons can be active concurrently is established.

TL;DR: Measurements of contrast sensitivity were obtained from isolated neurons in the lateral geniculate nucleus, striate cortex, and middle temporal visual area of macaque monkeys and show that many neuron in the middle temporal area are more sensitive than any cell encountered in early stages.

TL;DR: Most cortical neurons preferred modulation along vectors lying close to the achromatic axis and those showing overt chromatic opponency did not fall into the clearly defined chromatic groups seen in l.g.n.
