here's a tip:
when you are sitting around not using your hand (

) like on a bus or watching tv or something put it flat on something like a table or your leg and independently lift one finger at a time w/o lifting any of the others. then when you get good at that try doing it in different configurations like lifting thumb and middle (at once), then pointer and ring then middle and pinky. . . I also do a left hand thing where I put four fingers on the first four frets on the low E and bring the pointer and ring down a string (at once) w/o moving the other two and then bring down the middle and pinky. . .
fwiw these exercises have helped w/ my coordination greatly. gets your brain and your hand muscles to think more independently of your fingers . . .hope this helps
