Hi Dr Campbell, You've mentioned that C fibres have relay neurons, in this video and the last. However, of all the texts I've read on the internet, I am struggling to find this concept! Please help clear this up! Love your lessons. Thanks

Yes you are quite correct, I think I have corrected this in the later versions. My current understanding is that C fibre axons synapse directly with ascending neurones, whereas A fibres have the relay neurons. This only became clear in my own mind a couple years ago. Well spotted.
