Ever wonder how your dog knows what you’re feeling? Researchers in Budapest recently discovered a neural circuit in dogs’ brains that respond to the emotions in voices — both dog voices and human voices. The circuit seems to work similarly to a voice-detection circuit found in the human brain. This research was no small feat, as the dog subjects were required to lie completely still for 10 minutes at a time in an fRMI scanner. Thankfully, the dogs were motivated by treats and praise.

The light show at the Mickey Hart Band concert is part science, part art. Mickey Hart, best known as the percussionist for the Grateful Dead, wears an EEG cap while he plays which powers the light show for concert. Read more at NPR’s coverage: This is Musician Mickey Hart’s Brain on Music
In an effort to figure out how language helps babies learn, researchers studied infant learning in response to lemur screeches. Amazingly, 3 month old human infants learned in response to lemur shrieks. Although, this effect was gone by 6 months, at which point only human speech helped the babies learn.

As part of ongoing research to determine the causes of migraines, researchers using MRI discovered that the brains of those of us who suffer from migraines have white matter abnormalities that appear similar to mini-strokes. There is also a slightly increased risk for stroke for those who experience migraines with aura (flashing lights before a migraine), making it very important to practice stroke prevention.
