Figure 5From: Quantitative assessment of microglial morphology and density reveals remarkable consistency in the distribution and morphology of cells within the healthy prefrontal cortex of the rat Microglial cell size affects overall process characteristics. Sholl analysis of microglial cells divided into quartiles on the basis of size revealed a marked increase in process complexity as cell size increased. Overall differences by group were determined from the trapezoidal area under each Sholl curve (inset graphs). Black circles, Q1; white circles, Q2; black triangles, Q3; white triangles, Q4; * P <0.05; ** P <0.01; *** P <0.001.Back to article page
