TABLE 2.

Counts of Cx30-Immunoreactive Puncta Surrounding CNPase-Positive Oligodendrocyte Somata in Various Brain Regions of WT and Cx32 KO Mice^†

Brain area	Wild-type	Cx32 KO
Cerebral cortex	8.96 3 0.29 (291)	1.25 3 0.07 (305)*
Globus pallidus	8.38 3 0.34 (165)	1.09 3 0.08 (173)*
VL thalamus	8.22 3 0.42 (99)	0.78 3 0.08 (153)*
Hypothalamus	8.14 3 0.31 (197)	0.81 3 0.06 (185)*

^†Values indicate means ± SEM of the numbers of Cx30-immunopositive puncta associated with the surface of individual oligodendrocytes each viewed at a single focal plane in the indicated brain regions of wild-type (WT) and Cx32 knockout (KO) mice. Numbers in parentheses indicate the total number of oligodendrocyte somata examined in each brain region of three WT and three Cx32 KO mice.

^*Significantly different from WT. P < 0.001.
