we also observed two types of hrp-containing boutons ( presumably labelled anterogradely ) in the subsantia nigra after injection of hrp into the main body of the striatum : type 1 boutons contained large spherical vesicles , and formed symmetrical synapses mainly on dendritic shafts in the zona reticulata and in one case the dendrite was from a nigrostriatal neurone ;
