Women more sensitive to negative emotions than men

Men have a more analytical than emotional approach when dealing with negative emotions while women tend to focus more on the feelings generated by these emotions, a new study has found.
Researchers found that women are more sensitive to negative images compared to men, which may explain why women are more likely to suffer from depression and anxiety.
"Greater emotional reactivity in women may explain many things, such as their being twice as likely to suffer from depression and anxiety disorders compared to men," said lead author Adrianna Mendrek, a researcher at the Institut universitaire en sante mentale de Montreal.

In the study, researchers observed that certain areas of the brains of women and men, especially those of the limbic system, react differently when exposed to negative images.
For the study, 46 healthy participants - including 25 women - viewed images and said whether these evoked positive, negative, or neutral emotions.
At the same time, their brain activity was measured by brain imaging. Blood samples were taken beforehand to determine hormonal levels (eg, estrogen, testosterone) in each participant.

The researchers found that subjective ratings of negative images were higher in women compared to men. Higher testosterone levels were linked to lower sensitivity, while higher feminine traits (regardless of sex of tested participants) were linked to higher sensitivity.

Furthermore, while, the dorsomedial prefrontal cortex (dmPFC) and amygdala of the right hemisphere were activated in both men and women at the time of viewing, the connection between the amygdale and dmPFC was stronger in men than in women, and the more these two areas interacted, the less sensitivity to the images was reported.
"This last point is the most significant observation and the most original of our study," said co-author Stephane Potvin, a researcher at the Institut universitaire en sante mentale.
The amygdale is a region of the brain known to act as a threat detector and activates when an individual is exposed to images of fear or sadness, while the dmPFC is involved in cognitive processes (eg, perception, emotions, reasoning) associated with social interactions.

"A stronger connection between these areas in men suggests they have a more analytical than emotional approach when dealing with negative emotions," said Potvin, who is also an associate professor at the University of Montreal.
"It is possible that women tend to focus more on the feelings generated by these stimuli, while men remain somewhat 'passive' toward negative emotions, trying to analyse the stimuli and their impact," said Potvin.
This connection between the limbic system and the prefrontal cortex appeared to be modulated by testosterone - the male hormone - which tends to reinforce this connection, as well as by an individual's gender.

The study was published in the journal Psychoneuroendocrinology.
