Naruto Episode 46 English Dubbed

  They have a kekkie genkai (a special trait) which is passed down from generation to generation in the Hyuga clan. Like the Sharingan it lets them see and anticipate actions but the Byakugan also lets them see chakra flow (pretty much x-ray) and 390 degree vision except for one small blind spot a little above the nose coming down into a pretty complex angle. So Neji uses his Byakugan to do his almost famous  8 trigrams 64 palms with gentle fist which is the fighting style of the Hyuga clan that takes advantage of the Byakugan.
