Welcome to the on-line forum associated with the Biology 202 at Bryn Mawr College. Its a way to keep conversations going between course meetings, and to do so in a way that makes our conversations available to other who may in turn have interesting thoughts to contribute to them. Leave whatever thoughts in progress you think might be useful to others, see what other people are thinking, and add thoughts that that in turn generates in you.

As always, you're free to write about whatever thoughts you add this week. But if you need something to get you going, we've started looking at the nervous system from the input side, discovered again that perception is not independent of output (eye movements, focus control) and that what we see is an "informed guess" about what's out there.  Thoughts about either or both of those sets of observations/conclusions?
