Exercise 3

Mood changes are said to have a physiological basis in the brain. As a result, these changes are being studied. Because it is believed that mood changes are affected by the level of serotonin in the brain, a study has been conducted to determine what factors affect the level of serotonin. The blood of a large number of volunteers was taken throughout the year. This blood was then analyzed to see when the amount of serotonin was highest and lowest. It was found that the level of serotonin was affected by sunlight but it was not affected by temperature, air pressure or amount of rain. An increase in depression with reduced sunlight was also noted. Consequently, this depression has been named "Seasonal Affective Disorder," although it is often just called "winter blues."
