What would be the animal with the smallest neocortex (or perhaps species with the oldest neocortex) that demonstrates intelligent behavior associated with its neocortex?
I would like to imagine what the simplest demonstration of intelligence for an HTM might be. Perhaps biology could inspire this.
I guess it must involve a behavior that was learnt and then using that behavior in a different context - the animal demonstrates that a concept was learnt and can be generalized.
[Edit: as @Casey points out - I do not mean physical size I mean size in terms of number of neurons]
