When a computation is performed, some neurons are active during addition and others are active during subtraction
There are certain neurons in the brain that are specifically activated during certain mathematical operations
Most elementary school students probably already know that three apples plus two apples equals five apples
Some neurons in the brain become particularly active during addition tasks, while others become particularly active during subtraction tasks
The researchers benefit from a special function in the Epilepsy Department of the University Hospital Bonn
Some neurons fire only when summed
Five women and four men participated in the current study
It wasn't that some neurons responded only to the '+' sign, while others responded only to the '-' sign: "Even if we replaced the mathematical sign with words, the effect didn't change," said Professor Morman's research group.
In the study, tiny electrodes were implanted in the brains of five women and four men to measure the activity of individual neurons
This suggests that these discovered cells are actually encoding mathematical instructions for actions
Prof.
Mormann emphasizes: "This study marks an important step towards a better understanding of one of the most important symbolic abilities of humans - computing with numbers
