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. You're welcome to post here any thoughts that have arisen during the course this week (and to respond to thoughts others have posted)

Among the issues that have come up this week is the affect that imaging has on our conception of "reality" and explorations of retinal structure suggesting that we did indeed see things both without input, and without intending to.
