 Brain and Nervous System
And it is. The brain not only controls what you think and feel, how you learn and remember, and the way you move and talk, but also many things you're less aware of - such as the beating of your heart, the digestion of your food, and yes, even the amount of stress you feel.

 Handedness and Brain Lateralization
The term brain lateralization refers to the fact that the two halves of the human brain are not exactly alike.
This association between hand and brain captured the imaginations of researchers because it would be so useful (so easy, so non-invasive, so cheap) to study patterns of brain asymmetries by using a person's handedness as a marker for brain lateralization (direct methods involve neurosurgery, invasive drug testing, or expensive imaging techniques).
Clarifying the relationship between handedness and functional brain specializations, and learning more about the developmental and neurobiological mechanisms that underlie these relationships, may help us better understand a wide range of seemingly unrelated issues such as dyslexia, stuttering, human variation, comparative brain research, developmental neurobiology of the brain, and the origins of human language.
