Query: Slime Mould Logic Gates Based on Frequency Changes of Electrical
  Potential Oscillation   Physarum polycephalum is a large single amoeba cell, which in its plasmodial
phase,forages and connects nearby food sources with protoplasmic tubes. The
organism forages for food by growing these tubes towards detected food stuffs,
this foraging behaviour is governed by simple rules of photoavoidance and
chemotaxis. The electrical activity of the tubes oscillates, creating a
peristaltic like action within the tubes, forcing cytoplasm along the lumen;
the frequency of this oscillation controls the speed and direction of growth.
External stimuli such as light and food cause changes in the oscillation
frequency. We demonstrate that using these stimuli as logical inputs we can
approximate logic gates using these tubes and derive combinational logic
circuits by cascading the gates, with software analysis providing the output of
each gate and determining the input of the following gate. Basic gates OR, AND
and NOT were correct 90%, 77.8% and 91.7% of the time respectively. Derived
logic circuits XOR, Half Adder and Full Adder were 70.8%, 65% and 58.8%
accurate respectively. Accuracy of the combinational logic decreases as the
number of gates is increased, however they are at least as accurate as previous
logic approximations using spatial growth of Physarum polycephalum and up to 30
times as fast at computing the logical output. The results shown here
demonstrate a significant advancement in organism-based computing, providing a
solid basis for hybrid computers of the future.
