Are you a neuroscientist? You seem to have very little understanding of the brain and how it works. I can find research to support practically anything on the internet.
Human brains appear to come in at least two flavours: male and female. Now variations in the density of the synapses that connect neurons may help to explain
differences in how men and women think.
Even when intelligence levels are equal,
women and men excel at different cognitive tasks. But although brain size and neuron density differ between the sexes, these don’t seem to correlate with cognitive differences. So, Javier DeFelipe at
Complutense University in Madrid, Spain, and colleagues counted the number of synapses instead.
The brain tissue they analysed came from the left temporal cortex, a region of the brain involved in emotional and social processing, of four women and four men with epilepsy. The tissue itself was healthy, having been removed to allow doctors to access underlying damaged areas.
The men had up to 52% more synapses per brain “layer” in this region than the women. While the effect of high synaptic density in this region is unknown, the team suspects that there may be other regions where women out-synapse men.
In any case, says DeFelipe, although different synaptic densities indicates different circuitry between men and women, men
shouldn’t get too cocky: the density of synapses in mice is greater than in humans.
