Thiamine-like molecules in the cerebellar cortex of the rat: light and electron microscopic immunocytochemical investigation.

Immunocytochemical methods were used for studying the location of thiamine-like molecules in the cerebellar cortex of the rat. A positive reaction was observed in several synapses and in several dendrites. This reaction was associated with tubular formations and synaptic vesicles. A positive reaction was also found in several mitochondria and in glial cells. The possible role of thiamine-like molecules in cerebellar cortex is discussed.
