Subsynaptic localization of GABAA and GABAB receptors in the monkey STN. A. GABAA receptors revealed by pre-embedding immunogold. Most of the immunogold particles are located at extrasynaptic sites (white arrows). Some particles are at the edge (black arrow) of a symmetric synapse (arrowhead). B. GABAA receptors revealed by postembedding immunogold. The majority of gold particles (white arrowheads) are located at symmetric synapses (black arrowhead). C. Pre-embedding immunogold to reveal GABAB receptors. Gold particles at extrasynaptic locations on the plasma membrane are indicated by white arrows. Abbreviation: den, dendrite. Scale bars: A, B 0.5 μm; inset in B 0.1 μm; C, 0.25 μm. From Galvan et al. 2004, with permission.
