Abstract
Zinc-positive boutons, originating in the medial cortex of lizards, exhibit glutamate immunoreactivity. This finding supports the presumed homology between lizard zinc-positive boutons and the hippocampal mossy fibres of mammals, which are also glutamate-immunoreactive and zinc-positive. Zinc-positive boutons of lizards contain a chelatable pool of zinc located in the synaptic vesicles, as occurs in the hippocampal mossy fibres of mammals. These synaptic systems also contain glutamate, which indicates a possible simultaneous action of zinc and glutamate during synaptic transmission.Keywords
