"Although many studies have looked at the number of neurons, none has looked at the molecular composition of neuron connections. We found dramatic differences in the numbers of proteins in the neuron connections between different species".

"We studied around 600 proteins that are found in mammalian synapses and were surprised to find that only 50 percent of these are also found in invertebrate synapses, and about 25 percent are in single-cell animals, which obviously don't have a brain."

Most important for understanding of human thought, they found the expansion in proteins that occurred in vertebrates provided a pool of proteins that were used for making different parts of the brain into the specialised regions such as cortex, cerebellum and spinal cord.

Since the evolution of molecularly complex, 'big' synapses occurred before the emergence of large brains, it may be that these molecular evolutionary events were necessary to allow evolution of big brains found in humans, pri

Very interesting read.

Interesting. New to me via looking at 'quantum consciousness' are the structures within the neuron. It reminds me a bit of the history of the atom.

There is so much that is unknown about the brain, and the true powers that it beholds.
If we could use the unused parts of the brain, our intelligence could be endless.
If people could only think with understanding, and actually use it other then a hat rack, then this world would be a better place.
