Representational Capacity of Face Coding in Monkeys
... The amount of information that can be represented by the firing of a population of neurons depends on the nature of the neural code. In particular, the representational capacity is extremely sensitive to how information is distributed across the population of coding neurons. If each stimulus is repr ...
