As for the equation that will be used to determine whether a neurotransmitter triggers one of the intervals in a neuron, it will be as follows:
where the numerator represents the sum of the specific neurotransmitter (t) from the neurons that are active and connected, while the denominator represents the sum of how many neurons are active (where n is the set of neurons that are active). This function will be compared with the corresponding interval to see if it is within the range to trigger that particular action and render a particular neuron active. This is just an averaging function. It might need adjusting later but, for now, it should suffice for what I'm trying to accomplish. That's all as is. Hopefully, I'll have a flowchart and some pseudocode to post later.
Note: Special thanks goes to @M. Bindhammer for helping me correct the equation's presentation.
