>In the brain, we have precious little idea how learning is actually taking place.
It's Hebbian learning. When a post-synaptic neuron fires shortly after a pre-synaptic one fires, the synapse in question is strengthened (the surface area actually becomes larger). I hope he's talking about higher level concepts of learning, because otherwise he's wrong.
Hebbian learning is the little idea we do have. We don't know much more: how memories are represented by neurons, control, consciousness, vision, and almost anything.
