The question that might be on everyone’s mind after a fantastic first day of the the 26th annual meeting of CNS in San Francisco is: How did you sleep last night? That’s because Matthew Walker (UC Berkeley) delivered a riveting keynote address yesterday to kick off the meeting, all about the vital role sleep plays in, well everything — cognition, emotional regulation, mental health, physiological health earning, and lifespan! Following that talk, participants hear from a panel of cognitive neuroscientists about the relationship between psychology and neuroscience; panelists were: Lila Davachi (Columbia), Jennifer Groh (Duke), Catherine Hartley (NYU), and Sharon Thompson-Schill (University of Pennsylvania), with moderation by David Poepple (NYU). As always, we had tons of fascinating posters and lots of catching up with old friends and colleagues.
