A new study has found that differences between male and female brains are minimal, particularly in the part of the brain responsible for memory and emotional responsiveness.
The study, published in the journal Neuroimage and carried out by researchers at Rosalind Franklin University of Medicine and Science in Chicago, undertook a meta-analysis of 76 previous studies involving more than 6,000 people and found no significant difference in size between the hippocampi in male and female brains.
The hippocampus is a region of the brain believed to play a role in long-term memory. In humans, the hippocampus is a paired structure, with mirror image halves on each side of the brain. It is part of the limbic system, a network of nerves which controls basic emotions and drives such as fear and hunger. The hippocampus has previously been reported as larger in women than in men, relative to total brain volume—a finding which the study authors said has in the past been used to justify gender stereotypes such as women being in more touch with their emotions. However, a 2014 University of Cambridge study found that males on average had larger hippocampus than females. And the recent Neuroimage study confirmed that across all studies, no clear sex difference exists.
"Many people believe there is such a thing as a 'male brain' and a 'female brain,'" said Lise Eliot, associate professor of neuroscience at Rosalind Franklin and the study's lead author, in a press release. "But when you look beyond the popularized studies—at collections of all the data—you often find that the differences are minimal."
