Objects are represented by a single neuron.

Specificity coding

An object is represented by a pattern of many neurons firing. Likely the case for a lot of sensory activity.

Population coding

An object is represented by a pattern of a few neurons firing (most stay quiet). 

- Specificity coding
- Population coding
- Sparse coding
