OMG I’VE BEEN WAITING 2 YEARS FOR THIS GIF TO COME BACK. MY LIFE IS COMPLETE
Inflating a set of cat lungs
Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s a incredible wonder to this oddly inflatable organ.
Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory.
Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called aveoli, Mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.
A debt of gratitude is owed to cyborgraptor for her assistance in creating these gifs, as well as the students that help me film this demo.
How sleep aids visual task learning
As any indignant teacher would scold, students must be awake to learn. But what science is showing with increasing sophistication is how the brain uses sleep for learning as well. At the annual meeting of the Society for Neuroscience in San Diego Nov. 10, 2013, Brown University researchers will discuss new research describing the neural mechanism by which the sleeping brain locks in learning of a visual task.
The mounting evidence is that during sleep the brain employs neural oscillations—brainwaves—of particular frequencies to consolidate learning in specific brain regions. In August, Brown scientists reported in the Journal of Neurosciencethat two specific frequencies, fast-sigma and delta, that operated in thesupplementary motor area of the brain were directly associated with learning a finger-tapping task akin to typing or playing the piano.
