4. How can the ambiguity in single neuron bell curves be resolved?
- Decreasing the amount of presented stimulus
- Considering the population vectors and neurons in surrounding areas, different patterns seen at each stimulus value
- Adding another neuron, different patterns seen at each stimulus value
- Increasing the amount of presented stimulus
5. Which of these is a feature of SPARSE population codes?
