Many other studies document these attributes of the neocortex, but let’s summarize what we can observe from the neuroscience literature and from our own thought experiments. The basic unit of the neocortex is a module of neurons, which I estimate at around a hundred. These are woven together into each neocortical column so that each module is not visibly distinct. The pattern of connections and synaptic strengths within each module is relatively stable. It is the connections and synaptic strengths between modules that represent learning.
