They aren&#x27;t binary. They don&#x27;t have <i>two</i> values, they have a multitude of values (theoretically infinite if it&#x27;s truly continuous and not stepped between the minimum and maximum).<p>If neurons <i>only</i> responded to each other at the min and max value (or a couple thresholds&#x2F;ranges rather than strictly matching values), then it could be seen as binary. But they respond differently along the range of their inputs to produce a range of outputs, so not binary.
