Men and women's brains are wired in completely different ways which may explain why the sexes excel at certain tasks, brain scans reveal.
...Male brains are wired front to back, with few connections bridging the two hemispheres.
In females, the connections criss-cross between left and right.
...But ..."We know that there is no such thing as 'hard wiring' when it comes to brain connections. Connections can change throughout life, in response to experience and learning.
...Prof Heidi Johansen-Berg, an expert in neuroscience at the University of Oxford, said the brain was too complex an organ to be able to make broad generalisations.
"We know that there is no such thing as 'hard wiring' when it comes to brain connections. Connections can change throughout life, in response to experience and learning.
"Often, sophisticated mathematical approaches are used to analyse and describe these brain networks. These methods can be useful to identify differences between groups, but it is often challenging to interpret those differences in biological terms."
..."Increasingly, I think we are realising that drugs have to be personalised and that one drug is not necessarily going to be the same for each individual."
She said that most of the drugs available today had been tested on men, which may mean they are not necessarily the best design for women.
...not only are male and female brains different, but women's brains change throughout life in relation to fluctuating hormone levels.
"That may well affect disease states and how drugs work."
