How do drugs and drug use impact the brain? In this podcast from a recent SciCafe, Carl Hart, Associate Professor at Columbia University, shared his latest research and his sometimes surprising findings.
The next SciCafe, “Why Games Make Us Better and How They Can Change the World,” takes place on February 2, 2011. Learn more about this popular after-hours series featuring cocktails and conversation about cutting-edge science topics.

On Tuesday, January 25, the Museum kicked off the six-day Global Weekends: Brain and the Tibetan Creative Mind program with a traditional opening ceremony performed by monks from Drepung Loseling Monastery. Known in Tibet as Sa-chong, the ceremony, which includes chants, music, and mantras, prepared the area for the creation of a sand mandala. Over the next four days, the monks will complete the “Medicine Buddha” sand mandala in the Hall of Birds of the World.
Visit the Museum to see a traditional cham performance, learn about Tibetan arts, watch the making of the sand mandala, and more. The full schedule is available here. And, check out the clip of Tuesday’s opening ceremony below.

The goal of meditation — the act of consciously directing one’s attention to alter one’s state of being — is to take control of the mind so that it becomes peaceful, focused, and more aware. Going beyond the mental and emotional benefits, a new field of study known as contemplative neuroscience is revealing the real, physical effects of meditation on the brain. Using modern neuroimaging and electrophysiological methods, scientists can measure how the brain changes in response to contemplative practices.
This week, neuroscientist Richard J. Davidson,director of the Center for Investigating Healthy Minds at the University Wisconsin-Madison, will join other experts for a panel discussion about Tibetan Meditation, Brain, and the Arts (Thursday, January 27) and speak about how to Change Your Brain by Transforming Your Mind (Saturday, January 29). Visitors can also take part in Tibetan meditation at the Museum at one of many free meditation sessions led by Khen Rinpoche Geshe Kachen Lobzang Tsetan, abbot of Tashi Lhunpo Monastery in India. The Museum is celebrating Tibetan culture throughout the week, as part of the six-day Global Weekends: Brain and the Tibetan Creative Mind program, presented in conjunction with the exhibition Brain: The Inside Story.
In the meantime, check out a couple of recent articles on meditation and the brain:
“Can meditation change your brain? Contemplative neuroscientists believe it can,” a post on the CNN Belief blog, explores recent studies on the effects of meditation on the brain, including those conducted by Davidson, that have found that committed meditators experienced long-term changes in brain function. Research has shown that regions of the brain associated with positive emotions indicated an increase in activity — even in novice meditators.
A new study led by Massachusetts General Hospital researchers indicates that mindfulness meditation training can change the brain’s structure in just eight weeks. Participants who meditated for about 27 minutes per day showed increased gray-matter density in the hippocampus, the region of the brain important for memory and learning. Decreased gray-matter density in the amygdala, the region of the brain that plays a role in anxiety and stress, was also apparent.

On Thursday, January 20, neuroscientist Paul Glimcher of New York University and Rob DeSalle, curator of Brain: The Inside Story, will discuss the interdisciplinary field of neuroeconomics and how the brain enables humans to evaluate decisions, categorize risks and rewards, and interact with each other. Glimcher, whose books include Neuroeconomics: Decision Making and the Brain and Foundations of Neuroeconomic Analysis, recently answered a few questions about the discipline.
What is neuroeconomics?
Neuroeconomics is a highly synthetic and interdisciplinary effort to understand how both humans and animals make decisions.
What role does neuroeconomics play in our daily lives?
Decisions — the events that neuroeconomists seek to understand and predict — are embedded every aspect of our lives: what to have for breakfast, who to marry, or where to invest our retirement accounts. We make these choices effortlessly, but how? Over the last decade the basic outlines of the answer to that question have begun to become clear and the answers are surprising, exciting, and at times even troubling. It now seems clear that every day, at every action, our brains unconsciously compute and store the values of every event that befalls us. So I would have to say: neuroeconomics is our daily lives.

“Tweeting is a lot like the nervous system,” Curator Rob DeSalle told the crowd that gathered on Wednesday, January 12 for the first-ever Tweetup at the American Museum of Natural History—a comparison all the more appropriate coming from DeSalle, who curated the Museum’s interactive exhibition Brain: The Inside Story.
The evening kicked off with an after-hours tour of the exhibition, where Tweeters got a look inside a dancer’s brain, tried connecting neurons, and attempted to speak foreign languages. There was also time to talk with DeSalle and co-curator Joy Hirsch.
After refreshments, tweeters headed behind the scenes to learn about the brains of other creatures from Museum scientists and to get a peek at Museum collections. Christine Johnson, a curatorial associate in the Division of Invertebrate Zoology, discussed group decision-making and chemical triggers in ants. Ronald Clouse, a post-doctoral researcher, presented specimens of crustaceans and a few echinoderms while discussing how some of these simple organisms make sophisticated decisions.
