Also he claims dendrites connect to axons, which isn't impossible, but really dendrites connected to synapses, for the most part, or so I have learned in the past, I know there are cases where synapses connect to synapses and dendrites to dendrites, but the idea that dendrites connect to axons is new. Also his module is less complex than the complexity of even a single neuron, which does all of that, everything his module does.
