Imagine a typical situation that is likely to give rise to a bad temper within an individual: a person is awoken very early in the morning by a sound of a lawn being mowed next door.
Unlike expected awakening by an alarm clock, such unexpected awakening by a lawn mower is likely to leave the person in a bad temper, feeling grumpy or sulky.
I'm interested if there's a specific hormone or process that makes a person experience the feeling of grumpiness? Is it related to adrenaline and fight or flight instinct?
In other words, can experience of grumpiness be induced under laboratory conditions by using some combination of hormones/drugs?
