If you're basing this question on the common urban legend that we only use 10% of our brain, then the answer is no. Both geniuses and normal humans use 100% of their brains. You can't remove 90% of a brain's mass and have a person still work the same way. There is no dead space.

Causes of heart palpitations. Heart palpitations are frequently caused by stress or anxiety. In addition to making you feel terrible emotionally, stress can have a physical effect on your body. As a result, stress can cause the nerve endings that control your heart to fire more frequently or irregularly. Anxiety and panic attacks can also trigger palpitations by elevating adrenaline levels. Food and drink can cause heart palpitations. Caffeine, nicotine, and alcohol can all affect your heart rate and may also increase the likelihood of irregular heartbeats. Some medications can cause heart palpitations. These include asthma inhalers, over the counter medications such as pseudoephedrine, and thyroid medications.
