The structure of the human brain is more or less the same , about 40 percent gray matter and 80 percent white matter. But even then there are some structural differences in the brains of girls with boys due to which girls talk more than boys and again boys can understand the map better and faster. The answer has been found through various studies. Intelligence tests show that boys use 6 times more gray matter than girls and girls use 9 times more white matter. One of Gray Matter's tasks is to perform logical tasks such as location concepts , map reading , math , and problem-solving. White matter, on the other hand, connects the processing centers of the brain , which play a role in language skills , emotional thinking, and many other things at once. Since white matter is more commonly used in girls , they are more adept at linguistic communication. In fact , much more girls' brains are used for communication than boys, so they are more adept at using language as a tool to build social bonds , while boys use language as a means of exchanging information and solving problems. On average , a woman uses 6,000 words a day and a man 2,000 words a day. Communication between the two parts of the brain (hemisphere) is more effective in girls than in boys , so when boys concentrate on one task at a time , girls can do multi-tasking . It is thought that this is the most effective communication for girls. These differences have gradually developed since prehistoric times. When men went out in search of prey and their brains were used more to locate prey and solve problems , and women had to acquire linguistic skills to ensure the safety and growth of their homes and children. In this case, there is still a lot of research opportunities. It is hoped that more new information will emerge in the future.
