That preprint seems to be missing every single figure. From the text,<p>&gt;  The key feature of the model neuron is its use of
active dendrites and thousands of synapses, allowing the
neuron to recognize hundreds of unique patterns in large
populations of cells.<p>&quot;active dendrites&quot; and &quot;thousands of synapses&quot; sounds an awful like abstracting away a complex mathematical model to fit a particular definition of &quot;single neuron&quot;.
