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 folks at Backyard Brains have developed a device called RoboRoach that lets you control the movement of a cockroach with your iPhone! With the RoboRoach you can control a single insect, but what if you had control of an entire swarm? One researcher is trying to develop such technology to aid in search-and-rescue missions.

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
Using fMRI, scientists have located a part of the brain – just above each of the ears – that responds to quantities. It allows us to look at objects and quickly tell how many there are. This ability maxs out at five objects for most people, but anything less than that and we can quickly tell how many objects there are without even counting thanks to this region of the brain.

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.

The Japanese company Scentee has created an attachment for the iPhone that can spray out scents ranging from flowers to cooked meats. In their commercial, the company makes it seem like smelling food can actually hold off cravings, yet scientists beg to differ. You’ll be able to test it yourself in late November 2013 when Scentee makes its debut in the United States. Read more at NPR’s coverage: A Japanese iPhone Gadget Teases The Tummy With Food Smells

NPR – Don’t Call It A Mind-Meld: Human Brains Connect Via Internet. Using electroencephalography (EEG) and transcranial magnetic stimulation (TMS), researchers were able to have one person’s thoughts control another person’s actions. In this case, the subjects (who were also the researchers) were only playing a video game and pressing a button to fire, but still – very cool!
