(IMAGE) National Center of Competence in Research Synapsy Caption The dopaminergic neurons of low-anxiety rats (LA) show a stronger expression of the corticotropin-releasing hormone receptor 1 (CRHR1, red points) in the ventral tegmental area, as opposed to the rats with high anxiety (HA). The dopaminergic cell groups are shown in green and the clusters of all the neural cells in blue. @SANDI/EPFL Credit CARMEN SANDI/EPFL Usage Restrictions No restrictions.
