Schematic representation indicating the distribution of EGFP-positive cells (green regions) within and around the corpus striatum-example. Coronal section of a mouse brain according to Paxinos and Franklin (2003) at the level of the anterior end of the lateral ventricles. 1 Corpus callosum; 2 nucleus caudatus and putamen; 3, 4 core and shell of nucleus accumbens; 5 cortex telencephali; 6 lateral ventricle. EGFP-positive neurons and glial cells were spread along the injection canal which runs from parietal cortex to corpus striatum, as well as along the corpus callosum and in groups within the corpus striatum itself
