Researchers used single photon emission computed tomography SPECT to spot the differences between the brains of men and women. Using functional neuroimaging tools like SPECT, are essential for brain treatments.
The brains of women in the study were significantly more active in many more areas of the brain 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 centers of the brain were more active in men. SPECT 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.
Researchers examined healthy participants and patients with different psychiatric conditions such as brain trauma, bipolar disorders, mood disorders, psychotic disorders, and attention deficit hyperactivity disorder ADHD.
A total of 128 brain regions were analyzed while performing a concentration task. Understanding these differences is important because brain disorders affect men and women in different ways.
Women have significantly higher rate of depression, which is a risk factor for Alzheimer’s disease and anxiety disorders, while men have higher rates of attention deficit hyperactivity disorder ADHD and incarceration.
Their is an increased prefrontal cortex blood flow in women compared to men, this may be the reason why women tend to exhibit greater strengths in the areas of empathy, intuition, collaboration and self-control.
Researchers also found increased blood flow in limbic areas of the brains of women, which may be the reason why women are more vulnerable to anxiety, depression, insomnia, and eating disorders.
