The ideas of differences between the male and female brains have circulated since the time of Ancient Greek philosophers around 850 BC. In 1854, German anatomist Emil Huschke discovered a size difference in the frontal lobe, where male frontal lobes are 1% larger than those of females. [6]
The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
In some conditions, men's productivity is higher (for example, when "male" objects are used), in other conditions, women's productivity may be higher or there are no differences between the sexes. [54] Higher female ability in visual recognition of objects and shapes have also been found. [55] [56]
Differences in brain physiology between sexes do not necessarily relate to differences in intellect. Although men have larger brains, men and women have equal IQs. [ 19 ] For men, the gray matter volume in the frontal and parietal lobes correlates with IQ; for women, the gray matter volume in the frontal lobe and Broca's area (which is used in ...
The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic differences between male and female humans from an undifferentiated zygote. [3]
The "extreme male brain" or empathizing–systemizing theory views the autism spectrum as an extreme version of male-female differences regarding systemizing and empathizing abilities. [112] It's used to explain the possible reason why males with ASD score higher on systemizing tests than females with ASD. [113]
Research on the physiologic differences between male and female brains are based on the idea that people have male or a female brain, and this mirrors the behavioral differences between the two sexes. Some researchers state that solid scientific support for this is lacking.
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect, direct being the direct result of differences prescribed by the Y-chromosome (due to the SRY gene ), and indirect being characteristics influenced ...
