Preference for the postsynaptic targets of GSP, CT, and IX axons in control (C) and sodium-restricted (R) rats. Preference is indicated by the percentage of total synapses terminating on dendrites (hatched bars), spines (open bars), and axons (solid bars). In sodium-restricted rats the majority of synapses of GSP and CT axon terminals occurred on dendrites while the majority of synapses of IX terminals occurred on spines (significance not shown on graph). Compared to controls, a significant shift from the targeting of spines to the targeting of dendrites occurred in IX terminals of sodium-restricted rats (asterisks indicate a statistical significance of P < 0.02 between controls and sodium-restricted rats). Among controls, IX terminals formed synapses more often with spines than with dendrites compared with that of GSP (P = 0.0001) and CT (P = 0.0001) terminals (significance not shown on graph).
