This chapter is devoted to the biology of singing. Immediate effects have been extensively scientifically studied. Breathing and its synchronization with heart rate variability has been an important theme. Endocrine (endorphins, oxytocin, cortisol, testosterone) and immunological (TNF alpha, fibrinogen, immunoglobulines) reactions have also been studied during singing. In collective singing, cohesiveness is a major factor. Singing in a group during a choir rehearsal has stronger stimulation effects on oxytocin secretion than chatting in the same group. High levels of oxtytocin coincide with strong feelings of cohesiveness. In addition, oxytocin dampens anxiety and pain. Long-term effects of singing training and regular practice have been less extensively studied but there is evidence that singing training may influence such things as the brain´s development, the ability to synchronize heart and lung function, and the level of regenerative activity in the body.

The Brain

Heart rate variability (HRV) has long been associated with cardiovascular risk, especially after a myocardial infarction, but also in general. HRV refl ects and is used as a surrogate for the balance between sympathetic and parasympathetic systems in modulating the cardiovascular activity. A low HRV, traditionally associated to sympathovagal imbalance, is associated with a worse cardiovascular prognosis. Deep brain stimulation (DBS) is a surgical technique used for severe cases of Parkinson’s disease and other neurologic pathologies. DBS is performed in various areas of the brain and through different protocols. The claustrum, an area located between the external capsule and the insular cortex, was recently shown to be connected to Parkinson’s motor symptoms. As DBS in other regions of the brain has proven non-motor effects, like infl uencing the HRV, we sought to document the effect of claustrum stimulation on the sympatho-vagal balance (SVB). Our preliminary data indicates that claustrum stimulation inclines the SVB toward the latter, but more studies are required to observe the long-term effects of this type of stimulation.

Fight Or Flight

For more than a century, scientists have known that acute stress activates the fight-or-flight response. When your life is on the line, your body reacts instantly: your heart races, your breath quickens, and a cascade of hormones sets off physiological changes that collectively improve your odds of survival. More recently, scientists have come to understand that the fight-or-flight response takes a toll on the brain and the body—particularly when stress is chronic rather than acute. Systems designed to handle transient threats also react to stress that occurs again and again, for weeks, months, or years. It turns out that poverty, abuse, and other forms of adversity repeatedly activate the fight-or-flight response, leading to long-term effects on the immune system and brain, which in turn increase the risk for an array of illnesses, including asthma, diabetes, arthritis, depression, and cardiovascular disease. Pioneering neuroscientist Bruce McEwen called this burden of chronic stress “allostatic load.”
