Area 4 corresponds to the precentral gyrus or primary motor area. Area 6 is the premotor or supplemental motor area. Area 8 is anterior of the premotor cortex. It facilitates eye movements and is involved in visual reflexes as well as pupil dilation and constriction.
The vote to end debate on the Dream Act and move to a final vote received only 55 votes, short of the 60 votes needed to overcome a Republican-led filibuster. Forty-one senators voted no. Three Republicans - Indiana's Dick Lugar, Utah's Bob Bennett and Alaska's Lisa Murkowski - were among the yes votes.
But if the GOP blocks it from a vote, it requires 2/3 of the senate to move it to a vote. That's why you are confused. A majority to confirm. If the vote is blocked by filibuster (which the GOP is doing), then it takes 2/3 to overturn the filibuster and bring it to a vote, which requires 51 votes.
