Yeah, another topic I need to cover about bio neurology is how various
things are encoded.
In electronics, people normally assign a low value to a low voltage and
a high value to a high voltage.
In neurology, you could have a situation where a neuron could be injured
if it is over stimulated.
So in the brain you get situations where excitatory neurons often have a
rate of intrinsic firing, this firing will trigger a modulating
inhibitory neuron which will regulate the first neuron so that it is
regulated within a rate between 0 and some rate R. A third neuron could
be added to the circuit that synapses with the 2nd neuron. When the
third neuron fires, it inhibits the 2nd neuron which releases the
inhibition on the first neuron and causes it to fire more frequently.
This is called "disinhibition".
While there are examples in the brain where inhibitory connections do
what you would expect from an electronics background, DO NOT assume this
is always the case. It could be communicating a positive signal that is
merely inverted because it is necessary to clamp the range of the signal
and this was how eveolution did it in that circuit.
This connects back to what I was trying to say about feedback
connections. While the neural polarity of the connection is inhibitory,
that does not automatically mean its a negative feedback circuit as you
would assume, it is equally probable that because the fundamental
operation is to subtract to obtain an error signal, then either one
channel or the other will be inverted at some point.
It must also be clarified that by error signal I don't mean a fault in
the brain or neural circuit, but rather the signal which isolates and
highlights the information that the brain did not expect and therefore
should think about.
