Figure 3From: Co-release of noradrenaline and dopamine in the cerebral cortex elicited by single train and repeated train stimulation of the locus coeruleusEffect of locus coeruleus stimulation on extracellular NA and DA levels in the medial prefrontal and occipital cortex. Stimuli were delivered in bursts, as described in Methods, for a duration of 20 min (horizontal solid lines). Data are means ± SE, expressed as percent of mean basal value. Filled symbols indicate p < 0.05 with respect to basal values (Dunnett test)Back to article page
