(1) One method was to generate phosphene closest to the target point in regular arrays using weighted nearest neighbor search.

(2) Normally, the brain does not interpret tile phosphene patterns as identifiable objects.

(3) It is extremely phospherescent due to the amount of phosphene that it transmits onto the visual cortex.

(4) The investigators reasoned that if the synesthetes did have highly excitable neurons in the visual cortex, they would need less stimulation than the control subjects to see the phosphene.

(5) Where the new girl had been there was nothing but a twist of phosphene, peanut inflected; a stirring of empty air.

(6) Each participant received stimulation on the scalp near an area called the primary visual cortex until they saw a flash of light known as a phosphene.
