TABLE 2.

Microglial morphological parameters in various activation states.

Activation state	Soma shape	Soma size	Number of processes	Length of processes	Thickness of processes
Ramified	Round	⋅	⋅⋅	⋅⋅	⋅
Hyper-Ramified	Round/irregular/variable	⋅⋅	⋅⋅⋅	⋅⋅⋅	⋅⋅
Activated/reactive	Irregular/variable	⋅⋅⋅	⋅⋅	⋅	⋅⋅⋅
Amoeboid	Irregular/variable	⋅⋅⋅⋅	None	N/A	N/A
Rod	Elongated	?	⋅	?	?

Dots represent relative values. Incomplete information on rod microglial morphological parameters due to limited data and difficulty in comparing their unique morphology.
