BRAIN Journal-A Repeated Signal Difference for Recognising Patterns-Figure 2. Schematic of the same neuron N1, shared between 2 different patterns P1 and P2.

<p>It can be assumed that only one pattern fires during each time unit, where Rule 1 of the Introduction states that if a neuron fires a stronger signal for a pattern, it sends feedback to ask it to fire again, the next time unit. If it fires a weaker signal, the request is not to fire next time. Stronger and weaker relates to a more variable type of on or off. As the mechanism is not final yet, there could be some flexibility with it. Rule 1 also states that if the neuron does not fire for the current pattern, it receives the switch command from the last pattern it did fire for. Note that the actual firing event can produce either zero or some input and so an earlier event can also force a weak feedback signal. Rule 2 states that this particular feedback is only the on/off switch command and does not affect the size of the output value. A schematic of the idea is illustrated in Figure 2, which relates to the same neuron shared between 2 pattern events, at times t1 and t2. The schematic is described further in section 0.&nbsp;</p>
