Sparse Coding That Neurons That Sensory Neurons Employ to Reduce

Sparse coding that neurons that sensory neurons employ to reduce the number of action potentials necessary for a sense organ to get information to the sensory processing areas of the brain. This is analogous to what technique used in digital processing?

A) high resolution data processing where each data point is treated with equal processing
B) data compression where multiple data points with the same value are treated as one or two points
C) data compression where multiple data points are just averaged to give one uniform value
D) all of the above
