# Vehicles

• Behaviour and a single neuron. This page considers evidence that the firing rate of a single neuron (or cortical column) could affect an animal's perception and choice. But there are many instances (in fact, most) in which it would not. The page discusses the idea that what matters is whether the firing of this neuron (or cortical column of neurons) tips the feature vector, $\vec{r}$, from one recognised context (voronoi cell) to another. This is a rather different argument, I think, from saying that this neuron is (or these neurons are) a vehicle of representation. It would be good to discuss this.
