Figure 3. Terminal ends of microglial processes make occasional transient contact with each other.
(A) Neighboring microglia progressively extend their processes to meet transiently at a common point (circle) before disengaging and retracting. [Supplementary online material, movie S3] (B) A single cell extends adjacent terminal processes whose tips meet transiently at a single point (circle). [Supplementary online material, movie S4] Scale bar = 20µm.
