What a mess!
Scientists are finding that much of the brain’s organization is dedicated to fighting noise. One way to fight it is to calculate the average of several signals. When we hear a sound, hair-like structures on neurons in our ears wiggle. Their wiggling creates a pattern of voltage spikes, which the neuron then passes on to 10 to 30 other neurons. All of those neurons then carry the same signal toward the brain, where they can be compared. Each neuron degrades the signal in a uniquely random way, and by averaging all of their signals together, the brain can cancel out some of the noise.

Please sponsor Sarah so that she can raise loads of money for the Royal National Institute for Deaf People (RNID) whose ambition is to change the world for deaf and hard of hearing people. A very worthy cause.
This will be your only chance! She is only crazy enough to try this once!!
