Finding

The way the biological human neuron implements XOR is by a formerly unknown type of local response to inputs, which is low below the threshold, maximal at the threshold and decreases as the input intensifies above the threshold.

Why is this interesting?

  • XOR used to be impossible to compute without inhibitory mechanisms, but this is makes that possible.
  • Hence the human brain can use a single-layered network to compute the XOR function.
