31.   However, any genetic technique that affects brain function has the potential to generate controversy.

32.   How might nutrients improve brain function?

33.   If small vessels in the brain were similarly constricted, the result would be decreased blood supply and perhaps decreased brain function.

34.   In fact, they are such ancient neurological structures that other animals must have similar brain functions.

35.   In fact, at any age, with the right stimuli, new nerve cells and connections between them can form to enhance brain function.

36.   In the eeriest scene, the survivor disconnects HAL, whose speech becomes slurred and childlike as his higher brain functions are severed.

37.   In laboratory animals, endocrine disruptors have messed up systems for disease-fighting, growth, brain function, reproduction and more.

38.   Increased blood flow, as shown in splotches of light, may not be an accurate surrogate for brain cell function, some say.

39.   Inadequate intake of a number of nutrients can impair brain function.

40.   Indeed, it is not only our brain functions that apparently diverge, but just about every aspect of our physiology.
