Histochemical localization of synaptic zinc in the developing cat visual cortex

TLDR
The normal laminar, areal, and ultrastructural distribution of histochemically reactive zinc in the visual cortex of the adult cat as well as its development from birth are described.

Quantification of vesicular zinc in the rat brain

TLDR
The present study exploits a difference in staining pattern by applying computerized optic densitometry to light microscopic sections treated according to the Neo-Timm and the selenium methods, respectively.

Boutons containing vesicular zinc define a subpopulation of synapses with low AMPAR content in rat hippocampus.

TLDR
The levels of postsynaptic AMPARs may vary according to the presence of vesicular zinc in excitatory afferents to CA1, where zinc-positive and zinc-negative synapses may represent two glutamatergic subpopulations with distinct synaptic signalling.

Zinc co‐localizes with GABA and glycine in synapses in the lamprey spinal cord

TLDR
Results show that free zinc is present in inhibitory synaptic terminals in the lamprey spinal cord, and that it may function as a modulator of inhibitory neurotransmitter transmission in motoneurons.

Histochemical and electron microscopic study of mossy fiber endings in the hippocampal formation after oxine administration.

TLDR
Zinc in the hippocampal formation was studied by the sulfide silver method at 5, 10, 15, and 30 min after administration of 200 mg/kg oxine in rats and revealed a marked decrease of synaptic vesicles in the mossy fiber endings of the rats at 5 min after the oxine administration.

Stimulation-induced uptake and release of zinc in hippocampal slices

TLDR
It is reported that the mossy-fibre neuropil and cells of origin (dentate granule cells) take up zinc preferentially, and that electrical stimulation selectively facilitates both uptake of exogenous zinc into mossY-f fibre neuro pil and release of previously incorporated 65Zn from the tissue.

TLDR
The nervous tissue of the hippocampal formation was devoid of silver particles, as were the perikarya of the granular cells of the fascia dentata and the pyramidal cells ofThe hippocampus, and the cytochemical significance of zinc in nerve endings of thegranular cells is discussed.

Fiber systems in the olfactory bulb and cortex: A study in adult and developing rats, Using the Timm method with the light and electron microscope

TLDR
The structure of the olfactory bulb and cortex of rats is described using the Timm method, in which endogenous transition or “heavy” metals are precipitated with sulfide and then stained with silver, suggesting that the reactive metals are related to a membrane component which is recycled during secretion of synaptic transmitters.

On the normal histochemistry of trace metals in the brain.

TLDR
It seems appropriate to conclude that the staining pattern described light microscopically gives a valid picture of the distribution of one or more, but not all, important transition metal fractions within the brain.
