Human Brain Has a 'Map' for Perceiving Numbers

The human brain has a "map" for perceiving numbers, large and small, just like the sixth sense, reveals a new research.

While it a well known fact that human brain has topographical maps for the primary senses, such as sight, hearing and touch, for the first time a map for numerosity, or number sense has been discovered, according to Live Science.

Head injury or traumatic brain injury is a leading cause of disability among children and young adults that leads to varying degrees of physical and mental stability. Fortunately, it is also one of the preventable brain disorder.

Studies conducted in monkeys found that certain neurons in the parietal cortex became active when the animals viewed a specific number of items, but they did not find a map for numerosity.

Andreas Nieder, a neurobiologist at the University of Tubingen in Germany, said that while many laboratories have been investigating this idea intensively, Ben Harvey, a neuroscientist at Utrecht University in the Netherlands, succeeded in convincingly demonstrating a map of numerical quantity in the human brain.

The research also found that just like sensory systems higher cognitive functions might rely on the same organization principles.

Brain Exercises to Improve Memory
An active brain can certainly help in improving memory by strengthening the connections between neural impulses in brain.

The study is published in the journal Science.

About Brain Tumor
Brain tumors are the abnormal growth of brain cells that may be benign or metastatic. Brain tumors account for about 2.4% of all the tumor diagnosesandare most challenging due to their critically delicate location.
