"Overall, brain research has shown how the female brain is at work in more sections than the male just about all the time. It is on call in a way the male is not. To use an analogy: the male brain turns on, like a machine, to do its task, then turns off; the female brain is always on. This is an exaggeration, of course, for parts of the male brain are also always on, but when Gur compares the two brains in non-active states, the difference between the constantly “on” female brain and “on/off” male brain is startling. This difference is a primary reason males are so “task-oriented,” testing out as less able than females to do a number of different kinds of tasks at once; and why males react to interruptions in their thinking with more of a sense of invasion than females tend to, and combined with testosterone-based aggression, more forcefully."
