You don't need a brain to make decisions.

Even very simple biological systems—things like viruses, bacteria, yeast, and single mammalian cells—need to sample their environments and take appropriate actions. Often, these actions look very switch-like: the decision to go left or right, to metabolize one compound versus another, etc.

At this Science Café, Dan Siegal-Gaskins will briefly describe how genes alone, if "wired together" properly, are sufficient for this kind of switching behavior.

Here is an audio recording of this science cafe in mp3 format.
