Fluorescent Lights

Just learned the hard way that fluorescent lights operate at 25kHz. Our first attempt at neuronal recordings yielded a giant power spike at 25kHz which we discovered (by trial and error) was due to the lights in the lab. Thank goodness for the real-time FFT feature on the oscilloscope.

No sign of action potentials. I think we need to work out some grounding issues and try again tomorrow...
