Stress in the orchestra: Mood plays a part
Even professional orchestra musicians suffer from particular stress on the day of the concert and release more cortisol. For the first time, it has now been possible to demonstrate that, amongst others, the enzyme myeloperoxidase, which is regarded as a risk factor for cardiovascular disease, plays a part in the stress reaction in musicians. This effect is however dampened by an emotional factor: this is because a good mood reduces the stress-induced release of myeloperoxidase.

Hippocampal volume loss in depression reflects glial loss
Depression has been associated with reduced volume of the hippocampus in magnetic resonance imaging studies in humans. A new study now clarifies the cellular basis of these volumetric changes, which have been unclear until now. Beginning in the 1980s, a series of studies in rodents suggested that an area of the hippocampus, a brain region implicated in mood and memory, was particularly vulnerable to stress. When analyzing the brain tissue in detail, they reported loss of nerve cells called neurons with stress.
