Sleeping to Remember—And Forget - Dana Foundation


New research in neuroscience shows how cues during sleep can interrupt, or reinforce memories. Through functional Magnetic Resonance Imaging (fMRI), researchers can measure where in the brain these memories are stored, and what neural (or brain) pathways are involved in remembering specific events or people associated with the memory. The implications for learning are fascinating, as is the potential to disrupt triggers for stress and trauma.

10 Reasons 2010 Will Be Better: True or False?

2. We can improve our state of mind.
1. We should all resolve to be happy in 2010.

Reading a fascinating book by Robert Burton, On Being Certain or How We Know What We Know, which challenges us from a scientific point-of-view to check our assumptions at the door. Is my "pink" the same mixture of red-and-white that you see when you think of pink? Do I believe that science will one day reveal evidence for the rational view that all we see is random? Is "reason" the answer over "faith" because it is based on facts that can be proved?

Or do all these facts that we take for granted (I would say, "hold on faith", but that would be too ironic) only true until we find something "truer" that invalidates what we've deduced? And even if we can answer these questions, is there still a larger question about what set the random universe we inhabit (which is not even to tackle "knowing" multiple universes or multiverses and different understandings of time and space relative to other positions outside our tiny vantage point of knowledge) in motion?

Mind-boggling, no? What do you think?
