Figure 11.
Examples of the corticothalamic terminals in Pc labeled by the anterograde transport of BDA from T2. All terminals are small profiles and primarily contact (white arrows) GABA-negative (low density of the gold particles) profiles (B–G). A few contacts are made with GABA-positive (high density of the gold particles) profiles that contain synaptic vesicles (A). Scale bar = 0.5 μm.
