Why does neural coding in the auditory cortex exhibit sparseness, where only a small subset of neurons respond strongly to a given sound, rather than a broad activation?

💡 Explanation

Sparse coding minimizes entropy because it represents stimuli with fewer, more specific neural activations, therefore reducing the average uncertainty per stimulus. This efficient representation reduces redundancy, rather than increasing it as broad activation would; it also optimizes information transmission, rather than focusing on error correction coding uniformly across all neurons.
