Doing Calculations Boosts Mental Strength
Performing calculations such as addition and subtraction fires neurons in the brain region parahippocampal cortex which becomes active during the process, according to a study by researchers at the Universities of Tubingen and Bonn. The findings indicate that some of the neurons detected are active exclusively during additions, while others are active during subtractions. The researchers were able to identify neurons that were fired specifically during addition and subtraction tasks. However, different addition neurons became alternatively active during one and the same arithmetic task. It was as if the plus key in the calculator were constantly changing its location. The researchers said that the study marks an important step towards a better understanding of one of our most important symbolic abilities, namely calculating with numbers.
