Voltage Clamp

[Mark Fehr]

Hi,
    I'm an aspiring neuroscientist, a junior in college, and was wondering
if someone could help me out with a concept in my intro to neuroscience
class.  Can someone explain how the voltage clamp exactly works, and what I
read from it? I have a vague idea, and would like it to me more grounded.
Thanks
MARK
