The human hippocampus is not sexually-dimorphic
Neuroscientists currently believe that the male and female brain are much more similar than once assumed. Traditionally, differences observed in memory and spatial skills suggested that males and females have gender-specific differences in the structure and function of their hippocampus.
However, a new meta-analysis of 76 published papers, involving over 6,000 healthy individuals, has debunked the widely-held assumption that hippocampus size varies by gender.
Meta-analysis is a statistical technique that allows researchers to combine the findings from many independent studies into a comprehensive review.
The hippocampus was given its name because it resembles the shape of a seahorse. Hippocampus comes from the Greek hippos, "horse," and kampos, "sea monster." Humans have two hippocampi, one in the left hemisphere of the brain, and one in the right hemisphere. The hippocampus plays an important role in the consolidation of learning from short-term memory to long-term memory and in spatial navigation.
The October 2015 paper, “The Human Hippocampus Is Not Sexually-Dimorphic: Meta-Analysis of Structural MRI Volumes” was published in the journal NeuroImage. This study is the first meta-analysis of male/female differences in hippocampal volume based on published MRI studies of healthy participants of all ages to investigate whether the hippocampus is sexually dimorphic.
Lise Eliot, PhD, associate professor of neuroscience at Rosalind Franklin University of Medicine and Science, put together a team to conduct the meta-analysis of structural MRI volumes. The researchers found no significant difference in hippocampal size between men and women.

The illustration is misleading because the hippocampus is a substructure of the brain, not the entire brain and spinal cord.
ReplyDeleteHere's the hippocampus

It's an older part of the brain, so it's not surprising that men and women have similar hippocampi.
The illustration is meant to show man/ woman brain + spinal cord, because showing just the hippocampus will not mean anything for a lot of people.
ReplyDeleteWhat hippocampus is, where resides and the conclusion of the research -> explained in the article.
Corina Marinescu cool
ReplyDeleteNice the same, people manners is diferent.
ReplyDeleteIt would help people to have fundamental understanding of the hypocampus. For example, the ca01 hypocampus region is responsible for LTP, or Long term potentiation...memories. Do we need to know what memory is Linked to?
ReplyDeleteGuyzz use yr common sense n i think common sense is common in common people
ReplyDeleteMerci!
