Insect Brains Solve Problems>>>

Insects may have tiny brains, but they can perform some seriously impressive feats of mental gymnastics.

According to a growing number of studies, some insects can count, categorize objects, even recognize human faces — all with brains the size of pinheads.

Despite many attempts to link the volume of an animal's brain with the depth of its intelligence, scientists now propose that it's the complexity of connections between brain cells that matters most. Studying those connections — a more manageable task in a little brain than in a big one — could help researchers understand how bigger brains, including those of humans, work.
