  weird sine-wave oscillations?

  Posted: January 30th, 2012, 10:07am EST

  Hello,
  I was recording some ligand-gated ionic currents with a voltage step protocol, and I got puzzled, why are all these sine wave-like oscillations appearing at the negative potentials that seemingly do not carry any channel currents? Are they normal, or are they just instrumental noise? coz I think I definitely have some channel-mediated current at some more positive potentials on the left one.
  Just wonder if I can get any help?
  Thanks
  And
