1. What is coarse coding?
- Each neuron represents a range of possible input values
- Information about the stimulus is carried in the rate of firing
- Information about the stimulus is carried in the precise timing of individual spikes
- The same neuron can be used to detect the presence of a stimuli based on its similarity to a prototypical representation
