Odors increase Fos in olfactory bulb neurons including dopaminergic cells.

Abstract excerpt

Neuronal activity may lead to long lasting changes in cell phenotype through induction of genes such as c-fos which encode transcriptional regulatory factors. Odor-activated olfactory bulb cells exhibit increases in c-fos mRNA expression. The present study examined whether odor stimulation of awake rats also leads to increases in Fos protein in these cells. The phenotype of Fos-immunoreactive cells was partially...
