The neurotransmitter glutamate seems to play an important part in a number of psychophysiologic processes. Migraines after spinal cord injuries, for example, are common typically due to a release of high concentrations of glutamate. Parkinson's and Alzheimer's diseases also tend to show higher glutamate levels in patients. Tracking the levels of this chemical is very difficult, and so the development of new therapies that moderate the release of glutamate is impeded. Now researchers at Purdue...

One of the greatest stressors for dogs living in animal shelters is social isolation. Many studies have demonstrated that human interaction reduces cortisol in shelter dogs, with the possibility that longer periods of interaction may yield greater effects. These types of interventions are contingent upon removing the dog from the kennel and any such reductions in cortisol are often lost when the dog returns to the kennel. More recently, animal shelters are utilizing short-term fostering programs...
