Speaking personally, I completely took myself off caffeine during my pregnancies (mark you, since I am one of those who is nauseous throughout the whole of pregnancy -- and we're talking actual throughout the day vomiting here -- I was kind of off everything), and now a rodent study tells me I did good. The study found that even a small amount every day (the equivalent of 1-2 cups of coffee a day), resulted in cellular changes in the hippocampus -- a brain region crucial for learning and memory. The baby mice didn't seem to have any cognitive defects, but they were more active and less inhibited. Granted, that doesn't seem bad -- although -- I just had a thought ... the mice didn't seem to have much perseverance ... I wonder if the rise in ADHD has anything to do with all the caffeine mothers have been consuming? Pure speculation, but an interesting thought.

A neuro-economic study has found that the brain responds to the fear of losing money in the same way that it responds to pain. Which, as one researcher pointed out, shows that older brain structures common to all animals can be used to deal with abstract symbols.

And a study involving people blind from birth has revealed that there is an inherited component to facial expressions, and this appears to be most obvious in angry expressions.
