Has anyone every seen this before? I have a circuit that seems to work well, but only if I touch the board with my finger.

The part I have to touch is the "virtual ground". I divide the 9v battery into +/-4.5v with a voltage divider. I'm just curious if you have ever seen this before, and where I should start looking.
FYI. This circuit is connected to a leg of a cockroach. I am amplifying the spikes from it's neurons in the leg.
