Women have more active brains than men: Study
Women's brains are significantly
more active than that of men, especially in the areas involving focus, impulse
control, mood and anxiety, a study has found. The largest functional brain
imaging study to date compared 46,034 brain imaging studies to quantifying
differences between the brains of men and women.
The brains of women in the study
were significantly more active in many more areas than men, especially in the
prefrontal cortex, involved with focus and impulse control, and the limbic or
emotional areas of the brain, involved with mood and anxiety.
The visual and coordination centres
of the brain were more active in men.
SPECT (single photon emission
computed tomography) can measure blood perfusion in the brain. Images acquired
from subjects at rest or while performing various cognitive tasks will show
different blood flow in specific brain regions.
Subjects included 119 healthy
volunteers and 26,683 patients with a variety of psychiatric conditions such as
brain trauma, bipolar disorders, mood disorders, schizophrenia/psychotic
disorders, and attention deficit hyperactivity disorder (ADHD).
A total of 128 brain regions were
analysed for subjects at baseline and while performing a concentration task. Understanding
these differences is important because brain disorders affect men and women
differently. Women have significantly higher rates of Alzheimer's disease,
depression, which is itself is a risk factor for Alzheimer's disease, and
anxiety disorders, while men have higher rates of (ADHD), conduct-related
problems and incarceration.
The study findings of increased
prefrontal cortex blood flow in women compared to men may explain why women
tend to exhibit greater strengths in the areas of empathy, intuition,
collaboration, self-control, and appropriate concern.
