Many neurons in the human somatosensory cortex (Area 7 of Brodmann) possess an intensely negative-charged surface coat consisting of perineuronal sulfated proteoglycans which were stained with cationic iron colloid. This surface coat was stained doubly with cationic iron colloid and Golgi's silver nitrate. The result indicates that the perineuronal sulfated proteoglycans are identical with Golgi's reticular coating, whose existence and nature have previously been controversial. The result also suggests that Golgi's silver nitrate stains the core proteins of proteoglycans.
