Young girls and boys start acting like mature people once they reach puberty. Our small little neighbour boy who hops into the house seems to grow a tiny moustache and beard, his voice has become coarse and he seems all taller suddenly as he nears puberty. Adolescence begins at the onset of puberty marked by drastic changes in hormone levels and physical appearance. Beyond these, adolescents also experience drastic psychological transition. We have numerous hypothesis that changes in brain structure and development might be related to the hormones that trigger and control puberty. There are also studies proving that the structural development of subcortical brain regions is related to pubertal development during adolescence.
Now, scientists have made yet another discovery that brain networks develop differently in both males and females at puberty with boys showing an increase in connectivity in certain brain areas and girls showing a decrease in connectivity as puberty progresses. The researchers analysed brain scans of 147 girls and 157 boys aged between 13 and 15 years who were at different stages of puberty-from not having started to being fully mature. All the images were observed for how strongly the brain regions communicate with one another (functional connectivity) and the value of this functional community was associated with the level of maturity at puberty. The research team found that for similar changes in puberty status the functional connectivity in certain areas (those within the prefrontal cortex and parietal cortex) of the brain increased in boys by around 6.5% whereas it decreased by around 7.2% in girls. Women are easily prone to mood swings, anxiety and depression compared to men. Women are twice likelier to suffer from depression following puberty and the research clearly showed that puberty period is associated with significant brain changes in such mood-related brain areas. This study clearly shows that there are opposite changes of brain activity in boys and girls as they experience puberty and such changes can exist as the basis for the emergence of mood disorders. The researchers plan to take the study to the next step by analysing the role of brain connectivity in the onset of depression as these teenagers become adults. We cannot monopolize women with depression as men too are victims quite often but the neural pathways are different though the diagnostic criteria remain the same.

A study on almost a thousand brains in individuals aged between 8 and 22 revealed that male and female brains are wired differently. While women’s brain is connected across the left and right hemisphere the men’s brain is connected between the front and back regions. While the male and female brains showed few differences in connectivity up to the age of 13 the brain connections showed significant difference in 14-17-year-old children. Comments are closed.
