Synaptic output of CR cells. ac Synaptic contacts established by the CR cell axonal collaterals (dark DAB-labeled structures) on postsynaptic target structures. En passant synaptic boutons are located on dendritic shafts of variable size (de; ac). Note that all postsynaptic target structures are GABA-negative, as indicated by the absence of gold particles in these structures. d Example of an axonal bouton establishing a synaptic contact with a small caliber GABAergic dendritic profile as indicated by the presence of gold grains. Scale bars in ad are 0.5 μm
