the prefrontal cortex excited by the visual stimulus via the mediodorsal thalamic nucleus performs a top-down control over the dopaminergic cell activity, supervising simultaneous dopamine release in different striatal loci and thus promotes the interconnected selection of neuronal representations of individual properties of the visual stimulus and their binding in an integrated image. |
