Table 3. Percentage of overlap between the significant connections obtained by the four types of analyses of the human data.

	-S-G	+S-G	-S+G	+S+G
-S-G		78(+)	75(+)	89(+)
+S-G	81(−)		78(+)	86(+)
-S+G	30(−)	14(−)		97(+)
+S+G	42(−)	16(−)	88(−)

Percentage of overlap between positive connections is shown by (+) and between negative connections by (−). –S-G: analysis without spatial smoothing and without global signal regression; +S-G: analysis with spatial smoothing and without global signal regression; -S+G: analysis without spatial smoothing and with global signal regression; +S+G: analysis with spatial smoothing and with global signal regression;
