Bob Dylan, the single most important artist in the history of popular music, will be 70 years old on Tuesday, May 24. He was born Robert Allen Zimmerman in the flinty, scruffy city of Duluth, Minnesota, which teeters on the hills that plummet down to the shores of Lake Superior â a lake so large it has tidal movement.
Serotonergic receptors are found throughout the central nervous system and are involved in the regulation of the sleep-wake cycle, behavior, appetite, temperature and muscle tone, and serotonin neurotransmission is involved with the regulation of gastrointestinal motility and vascular tone.
Although many environmental factors can affect serotonin levels, one specific contributor to healthy serotonin production is physical activity. In research studies, the effects of exercise on serotonin levels has been studied, particularly in respect to conditions like depression, fibromyalgia and anxiety.
