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.

Palpitations Symptoms. Palpitations are the unpleasant sensations of irregular and/or forceful beating of the heart in the chest. This symptom can be caused by a change in the rate or rhythm, or by an increase in the force of the contraction of the heart muscle. 1  In some patients with palpitations, no heart disease or abnormal heart rhythms can be found. 2  In others, palpitations result from abnormal heart rhythms called arrhythmias.
