Figure 4  Dendrites' length and spines' morphology evaluation. [A] Total length of the dendrites per neuron in different groups, including control, olive oil, curcumin, SD, SD+curcumin, SD+olive oil, grid, grid+curcumin, and grid+olive oil. [B] Density of the dendritic spines. The density of mushroom spines per neuron has been shown in the mPFC of different groups. A significant difference has been indicated between SD and other groups (P < 0.05). [C] The density of thin spines per neuron has been shown in the mPFC of different groups. A significant difference has been revealed between SD and other groups (P < 0.01). [D] The density of stubby spines per neuron has been shown in the mPFC of different groups. A significant difference has been indicated between SD and other groups (P < 0.05). Each dot represents an animal in different groups. The horizontal bars show the means of the parameters in the study groups. P-values have been indicated.
