Why am I attending a Creative Computing Class?

Do I need a reason? No. If you love to learn there is no need of a reason but the pleasure of learning. However time and resources are limited and I need a less idealistic reason.

I have been trying for a long time to use open-source hardware and software to conduct my experiments, specially the electrophysiolgy ones, where I need to record the tiny electrical currents created by the neurons in the brain to communicate between them. This currents underlie all our capacities from moving a finger to paint El Guernica, or develop the Neural Doctrine, assuming that you are Picasso or Ramón y Cajal.  The electricity I measure is tiny. The outlets where we plug our devices like the tv, or the computer have a voltage of 120 Volts. If you take 1 out of those 120 and you divide it in 100000 parts, you have 1 microVolts. The electricity I measure goes from 5 to 100 microVolts. As you can imagine that requires very sensitive electricity detectors. We have them but they are so sensitive that catch the static electricity that is all over and that usually is bigger than the brain signal we are interested on.
