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.
The Senate's cloture rule originally required a supermajority of two-thirds of all senators present and voting to be considered filibuster-proof. For example, if all 96 Senators voted on a cloture motion, 64 of those votes would have to be for cloture for it to pass; however if some Senators were absent and only 80 Senators voted on a cloture motion, only 54 would have to vote in favor.
