Left-hemisphere dominance for processing of vowels: a whole-scalp neuromagnetic study.

abstract：:Using NADPH-diaphorase (NADPH-d) staining as a marker for the enzyme nitric oxide synthase (NOS) we investigated the possible sites of nitric oxide (NO) synthesis in the olfactory pathways of an insect brain. Staining of frozen sections revealed NADPH-d activity in neurones and in glial cells. A cluster of intensely s...
