Nerve cells key to making sense of our senses

A team of scientists has unraveled how the brain processes complex sensory signals, using a relatively simple computation performed by single nerve cells. The study confirms and extends a computational theory developed earlier, predicting that neurons fire in a manner predicted by a weighted summation rule.
