Essay – The Brain

Male constantly outdo female on spatial skills, comprising mental rotation that is the capability of identifying how 3-D object would appear in space if rotated. In this paper, we will justify why men have better-developed spatial skills, hence smarter than women have.

The parietal lobe usually differs among women and men, with female’s parietal lobes having correspondingly thicker grey matter. In women, the thicker cortex located within the parietal lobe is related to worse mental rotation skills, whereas the parietal lobe’ surface area is increased in male, in comparison to female. Besides, in male, the greater surface areas of the parietal lobe is connected directly to better performance mainly on “mental rotation tasks.” Usually, it is probable that the bigger surface area within the parietal lobes of men results in the rise in functional columns that in the cortex are chiefly the processing unit. This might signify the specialty for particular spatial skills in males. The cortex, in women brains, is formed differently since the neurons are packed together more closely in two and four layers of the temporal lobe, and in three, five and 6 layers of the prefrontal cortex.

Men seem to have much development in specific regions of the right hemisphere that aids in providing them with enhanced spatial skills such as mapping, measuring, and mechanical design among others. Men have a larger cerebral compared to women of similar health status and age. Men brains are larger than women brains in every location, although men enlargement is most conspicuous bilaterally within the frontal-occipital poles. In some cognitive tasks, the two hemispheres operate differently among the men and the women brain. Interestingly, for great spatial skills, men’s higher right hemispheric activation is usually related to superior spatial problem-solving. The men differentiated brain normally has a thicker right hemisphere. Therefore, another probable reason why men seem to have better developed spatial abilities.

The inferior parietal lobule is considerably larger in male compared to female. More particular, in men, IPL’ left side is larger compared to the right. Although in the female, the asymmetry is reversed, even though the variance between right and left sides isn’t as large as that in a male. It appears that the IPL is associated with mathematical potential. The inferior parietal lobe often allows the input of the brain process principally from the senses. Besides, it assists in perception. The left IPL is related to the perception of speed and time, and the capability of rotating 3-D figures within the brain. Male typically have a larger inferior-parietal lobule, which is supposed to influence mathematical capability than women.

Besides, the male brain is often more lateralized since functions are achieved in one hemisphere. On the other hand, the female brain is less lateralized and more integrated; because of the specialized brain, men have the ability to perform two different things concurrently. However, since information is normally processed in both hemispheres, it is hard for a female to carry out more than one task at a time. One hemisphere seems to dominate in men’s brain for any particular activity, while the females’ one hemisphere cannot carry out one task at a given time. Hence, it is evident that males have better developed spatial abilities than females.
