Brain wiring

Meet the new effort to map the wiring of the human brain. The brain connectome "offers a unique opportunity to understand the complete details of neural connectivity. The Human Connectome Project (HCP) is a project to construct a map of the complete structural and functional neural connections in vivo within and across individuals." Do check out the images at the link location.

The neuroscience of creativity

How is it that some of us are so highly creative? Doctor (and musician) Charles Lamb is a scientist who studies musical improvisation using fMRI scans, and he has developed theories that apply to all forms of creativity. The subjects were asked to play written music and then to improvise using a mini-keyboard while they were jammed into an fMRI scanners. The brain works very differently when it improvises. It appears that an area of the brain involved in self-monitoring turning off and an area that is autobiographical/expressive turning on. His hypothesis is that the latter area needs to shut off so that we are not inhibited and we are not afraid to make mistakes. Lamb found that when jazz musicians were "trading fours" taking turns improvising four-bar sections, their language areas of the brain lit up (11:30). He also did an experiment regarding free-style hip hop rap music by putting a rapper into an fMRI machine, performing a pre-written tune and a free-style session. When free-style is being done, visual and motor coordination areas light up.

9/11 as an excuse to say stupid things.

I work in a big office building located in downtown St. Louis, the "Bank of America Plaza." Early this week, I was interviewed for a newspaper article, and I needed an updated photo of myself. A coworker offered to snap that photo using a small digital camera. We want down the elevator to the first floor public lobby of the building, at street level, where we found a large neutral colored wall that we could use as a backdrop for my photo. I stood in front of the wall and my coworker stood about 10 feet away from me. As she took a photo of me a security guard suddenly approached. Me: "In the lobby? In a public lobby?" Guard: "You may not take any pictures here. It’s because of 9/11 and homeland security." Me: "I understand that your employers have instructed you to say these sorts of things, but what you have just told me is about the most idiotic thing I've ever heard. My coworker is simply trying to take a picture of me in front of a wall." Guard: "Sir you cannot continue doing this. You will need to take pictures elsewhere." We left. Apparently, taking pictures of me threatens the United States. Or maybe the threat was taking a picture of the wall behind me. Certainly, the guard made it clear that the building owners prohibit any sort of photos in the lobby. We walked across the street and threatened the United States by taking my photo inside the lobby of a office building across the street, where friendly security guards don’t appreciate the risk of what we were doing. Instead, they naively laughed at our stories about security guards in my own office building.

The science of making butter, and more

Robert Krampf teaches us how to make butter, explaining the science of butter-making. I certainly learned some things along the way. In the following video, he talks about infrared, a color that our eyes can't see. I learned of these videos, and much more in this list of 100 science videos for science teachers.
