A Nerve Cell's Pleasure and Pain

Greetings :)

Let me start by saying that I'm a layman, and don't really know a whole lot
about this subject. An idea came to me and I thought I'd present it.

I just read a posting in this same newsgroup that seems to have relevance
with this conversation ...... (I make no claims that this is proven
information or that it's original author does so. It simply presents an
interesting idea.)

So when Bill is presenting:

Perhaps ....

1. "neural pleasure" and "neural pain" are defined as which, out of a
neuron's range of responses, is considered as such.

Perhaps 2 of 3 possible neurotransmitters a neuron is capable of releasing
is pleasure, and the remaining (or not firing at all) is pain?

2. Perhaps if a neuron receives stimulus that calls for a pleasure response,
the neuron responds by releasing a specific neurotransmitter depending on
intensity/frequency of the stimulus? High intensity/frequency release Option
A Neurotransmitter, low intensity/frequency release Option B

3. Perhaps if the stimulus is too intense, or too high a frequency,
therefore threatening damage, it releases Option C Neurotransmitter. Thus
alerting the brain of the danger.

4. The stimulus doesn't call for a response (pain by rejection of action)
and the neuron ends up not doing anything?
