Scientists uncover new clues about brain function in human behavior

...aintain social goals governing an interaction; the medial area has been associated with empathy and regulati...sts observed increased activity and linkage in the medial region, which is consistent with the high level of empathy exhibited by people with Williams Syndrom...

Biotechnology's newest chemical tool

...flon sheath pulled by a DC motor. So the proximal, medial and distal phalanges, those bones between your finger knuckles, are all driven by the same tendon. This approach is called underactuation as there are more Degrees of Freedom than Degrees of Movement (motors); it means the prosthesis has a self-adapt...

Clocking in Pillow Time without the Pillow

The researchers compared these results to suggest a biological basis for the drug's effects. Previous studies h...

Noise And Delays Explain Why Some Genes Oscillate In Activity

The researchers compared these results to suggest a biological basis for the drug's effects. Previous studies h...

Tracking the memory trace

...formed in a pair of neurons called the dorsal pair medial neurons, but only 30 minutes after the fact and only through the mediation of a gene called, ironically, amnesiac. (A memory trace is a chemical change in tissue that represents the formation of a memory.) The study appears in the current issue of th...

How the octopus forms an elbow

...t near the suckers that have grasped the food. The medial joint typically exhibits the most movement during food retrieval. The authors also found evidence that, like certain types of human arm movements, octopus fetching movements are controlled in terms of joint angles, rather than by a system that reli...

Oops! Researchers publish new findings on the brain's response to costly mistakes

...he rACC, a larger region of the brain known as the medial frontal cortex. Working with Joe Himle, Ph.D., and Laura Nisenson, Ph.D., from the U-M Anxiety Disorders Program in the Department of Psychiatry, he performed a study in OCD patients that showed heightened response to errors in the same area. Now, t...

Study reveals how ADHD drugs work in brain

Medium is the message for stem cells in search of identities

...t goes on to generate a brain structure called the medial ganglionic eminence, which in turn is believed to give rise to a population of early neurons in the developing cerebral cortex, a structure that helps coordinate sensory, motor and cognitive function. "This is significant because this molecule is ...

The brain's motivation station

...as well as the learning-related hippocampus in the medial temporal lobe (MTL) of the brain. Activation prior to scene visualization suggests that the brain actually prepares in advance to filter incoming information rather than simply reacting to the world. Activation of the MTL is associated with higher b...

Where we change our mind

"Our results provide evidence that activity in different regions of the prefrontal cortex reflect critical computational components involved in decision making in uncertain environments," concluded the researchers. "This fits well...

Study offers window into human behavior, brain disease

...rtex degenerate in ALS and specific memory-forming medial temporal lobe neurons die in early Alzheimer's disease. "We hope to add von Economo neurons to that list," says Seeley. "It's a pretty important list to fill in, but for FTD there just hasn't been a good candidate until now. We think we've found i...

The effects of smoking on fractures and ligament injuries

...ll, researchers examined the effects of smoking on medial collateral ligament (MCL) injury. They performed MCL surgery on 40 mice, half of which were exposed to cigarette smoke 6 days a week for two months. Researchers quantified cellular density at the site of injury and used Type I collagen gene expressio...
