Leptin Has Powerful Effect On Reward Center In The Brain

09-29-2006 · ScienceDaily

Leptin, a hormone critical for normal food intake and metabolism, exerts a strong effect on appetite by acting in the mid-brain region as well as in the hypothalamus, according to a Yale School of Medicine study in Neuron.

Impulsiveness linked to activity in brain's reward center
12-19-2006 · EurekAlert!
A new imaging study shows that our brains react with varying sensitivity to reward and suggests that people most susceptible to impulse -- those who need to buy it, eat it, or have it, now -- how the greatest activity in a reward center of the brain. The study appears in the Dec. 20 issue of The Journal of Neuroscience.

How the brain handles surprise, good and bad
09-19-2007 · EurekAlert!
Whether it's a mugger or a friend who jumps out of the bushes, you're still surprised. But your response -- to flee or to hug -- must be very different. Now, researchers have begun to distinguish the circuitry in the brain's emotion center that processes surprise from the circuitry that processes the aversive or reward "valence" of a stimulus.

Researchers show how obesity causes breakdown in system which regulates appetite and weight
03-06-2007 · EurekAlert!
Research led by scientists at the Oregon National Primate Research Center demonstrates how obesity causes the breakdown of a brain system that regulates appetite. Specifically, the scientists determined that leptin resistance prevented a portion of the brain called the arcuate nucleus from taking part in an important signaling function that regulates appetite and body weight.

Study: Re-engineered Gleevec reduces heart risks
12-03-2007 · EurekAlert!
Using a new bottom-up approach for rational drug design, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have reengineered the powerful anticancer drug imatinib -- best known by its brand name Gleevec -- to more specifically target one type of cancer while potentially curbing a rare life-threatening cardiotoxic side effect. The re-design strategy employed in the study is broadly applicable to reducing side effects in other drugs.

New study shows Rescue Remedy is an effective all-natural stress, anxiety reliever
06-28-2007 · EurekAlert!
A just published scientific study conducted by researchers at the University of Miami School of Nursing in conjunction with The Sirkin Creative Living Center (SCLC) has found that Rescue Remedy, an all-natural remedy created from flower essences, is an effective over-the-counter stress reliever with a comparable effect to traditional pharmaceutical drugs yet without any of the known adverse side effects, including addiction.

How the brain weaves a memory
11-08-2006 · EurekAlert!
Memories of events comprise many components -- including sights, sounds, smells and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus. A central question has been whether the hippocampus receives an "episodic packet," or a collection of perceptual strands that it must integrate into a memory.

Common cancer treatments toxic to healthy brain cells
11-29-2006 · EurekAlert!
Common drugs used to treat cancer may be more harmful to healthy brain cells than the cancer cells that they are intended to destroy, according to a new study. The results, which also indicate that chemotherapy may cause long-term brain damage, represent the closest that scientists have come to pinpointing the underlying physiological cause of "chemo brain," a common side effect of cancer treatment that scientists are only now beginning to comprehend.

Orexigen: Laboratory studies show Contrave acts on specific brain pathways to reduce food intake
10-23-2007 · EurekAlert!
Laboratory studies show the combination of bupropion and naltrexone (the components of Contrave) acts in a part of the brain where food reward pathways are located and resulted in a 95 percent reduction in food intake in obese mice. This mechanism of action may differentiate Contrave from other obesity therapeutics. Concurrent with these studies, Contrave is in phase 3 clinical trials.
