Researchers in the University of Alberta's Faculty of Rehabilitation Medicine have made an important discovery that could lead to more effective treatments for spinal-cord injuries. Karim Fouad and David Bennett have identified one of the body's natural self-repair mechanisms that kick in after injury. To help understand the discovery the researchers say it is important to first describe the neurons in the spinal cord that control muscle contractions. These neurons represent a fairly...

Feeding the amino acid tryptophan to young female pigs as part of their regular diet makes them less aggressive and easier to manage, according to a study by Agricultural Research Service (ARS) scientists and cooperators. The tryptophan-enhanced diet reduced aggression and overall behavioral activity among young female pigs during the 8-month study. Tryptophan, which is only acquired through diet, is the precursor for the calming cerebral neurotransmitter serotonin. Keeping swine calm is...

Scientists at Emory University School of Medicine have discovered unexpected properties for a precursor to melatonin, the hormone that regulates sleep cycles. Melatonin is produced from the neurotransmitter serotonin in a daily rhythm that peaks at night. Melatonin's immediate precursor, N-acetylserotonin, was not previously thought to have effects separate from those of melatonin or serotonin. Now an Emory team has shown that N-acetylserotonin can stimulate the same circuits in the brain...

Doctors closing in on mysterious cause of death in infants Taking the next step in more than 20 years of research, researchers at Children's Hospital Boston have linked sudden infant death syndrome (SIDS) with low production of serotonin in the brainstem, based on a comparison of brainstem samples from infants dying of SIDS compared to brainstems of infants dying from other, known causes. The findings, published in the Feb. 3 issue of The Journal of the American Medical Association, may give...

An excess of one type of serotonin receptor in the center of the brain may explain why antidepressants fail to relieve symptoms of depression for 50 percent of patients, a new study from researchers at Columbia University Medical Center shows. The study in a mouse model is the first to find a causal link between receptor number and antidepressant treatment and may lead to more personalized treatment for depression, including treatments for patients who do not respond to antidepressants and...
