London, Sept 9 : They say men are from Mars and women from Venus. Now, a group of researchers has backed this adage by providing scientific proof that the brains of the two sexes are distinct.
According to the research team, the variations in the density of the synapses that connect neurons may help to explain differences in how men and women think.
Even though the 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. Therefore, Javier DeFelipe at Complutense University in Madrid, Spain, and colleagues counted the number of synapses instead, reports New Scientist.
