Nerve Cells Key To Making Sense Of Our Senses

A team of scientists has unraveled how the brain manages to process complex, rapidly changing, and often conflicting sensory signals to make sense of our world. The answer lies in a relatively simple computation performed by single nerve cells, an operation that can be described mathematically as a straightforward weighted average. The key is that the neurons have to apply the correct weights to each sensory cue, and the authors reveal how this is done.

The study represents the first direct evidence of how the brain combines multiple sources of sensory information to form as accurate a perception as possible of its environment.
