When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond differently to different faces. For example, Arthur's face causes three neurons to fire, with neuron 1 responding the most and neuron 3 responding the least. Roger's face causes three different neurons to fire, with neuron 7 responding the least and neuron 9 responding the most. Your results support coding.

Sparse coding

Explanation:

Sparse coding can be described or explained as a situation where items are encoded or represented by strong activation of a relatively small sets of neurons.

It should be understood that neurons code for the intensity of stimulus , and this is done in two ways which are

* Frequency coding...here, the firing rate of sensory neurons increases with increased intensity, and

* Population codinghere, the number of primary afferent responding increases.

In this case, the results derived or gotten from both Arthur's and Roger's faces supported the sparse coding.
