Figure 6. Morphological and neurochemical features of prefrontal cortico-thalamic synapses in the ventral anterior nucleus.

Figure 6

A, center, Proportion of small (light red) and large (light blue) boutons from prefrontal axons in the ventral anterior nucleus. B, Most large boutons formed synapses with CB+ dendrites of thalamic projection neurons (dark blue) and very few established synapses with PV+ dendrites (grey); C, most of these CB+ dendrites contained NR1 receptors (navy blue), few had other receptors, but not mGluR1a (light grey). B̀, Most small boutons formed synapses with PV+ dendrites of thalamic projection neurons (light orange) and few formed synapses with CB+ dendrites (grey); C̀, most of these PV+ dendrites contained mGluR1a receptors (red), and fewer had other receptors (light grey).
