Are neurons in humans different of the ones of other animals?
Ok thanks a lot, that's very interesting.
I also wonder what happens to the ions that are exchenged via synapses between different neurons. Are some of them lost, and if so where do they go? I guess there's some loss, otherwise one could eat some potassium, calcium, etc. at birth and the brain would never need it again.
I also find surprising the fact that all animals require many different type of ions such as sodium, potassium and calcium for their brain to function. I would not have thought that bees, ants for example or snails would have needed them.
