Electrodes,
inserted into the septal area of rats caused the animals
seek more of the same "pleasure." After
lobotomy, patients claimed that pain did not
"hurt." How could mere electrical impulses from
nerve cells generate mysterious responses, like pain and
pleasure? This article suggests that these events are
generated by drives, triggered by emotions from the
limbic system. Drives are processes of the mind, managed
by intuition, a pattern recognition algorithm.
SUBCONSCIOUS DRIVES MAKE YOU UNHAPPY
It was
not maths, but recognition. For centuries, science
searched to uncover the enigma of the mind. Was there a
link between the body and the mind? On the other hand,
was the material world merely an imagined picture in the
mind? If not, was the mind a maths and logic processor?
If it was, could a computer mimic the mind? Even if it
could, could such a logic processor become angry, or feel
dread? The last idea sounded absurd. In the end, it was
the more irrational and illogical processes of the mind,
which baffled science. How could any logical process ever
generate tears and smiles? Actually, this was not so
impossible. There was a simple answer. The mind did use a
logical process. But, it was not a maths processor, but a
pattern recognition entity. The mind recognized patterns.
Its interpretation of recognized patterns in the
environment were often irrational and illogical. But the
pattern recognition process was logical. Intuition was
its enabling algorithm (IA).
The
recognition of combinations. The evidence of a
recognition process was universal. Nerve impulses were
recognized as feelings and emotions. Nerve endings or
sensors reported on feelings from tissues all over the
body. These sensations included sharp pain, burning pain,
cool or warm temperature, itching, muscle contraction,
joint movements, soft touch, mechanical stress, tickling,
flushing, hunger and thirst. Electrical excitation of
certain parts of the temporal lobe, caused intense fear
to be produced in patients. Excitation of other parts
caused feelings of isolation, loneliness, disgust, or
even pleasure. Out of the millions of nerve fibers which
relayed these messages, the mind differentiated
combinations of active nerve impulses to identify a
feeling of hunger, thirst, or much else.
Combinatorial
coding. The IA concept was that pattern recognition
by the mind identified objects and events through a
neural combinatorial coding process. This recognition
process was recently acknowledged by science for
olfactory neurons. Animals instantly recognized millions
of smells through this process. A Nobel Prize
acknowledged that discovery in 2004. For IA, the vision
went further. The massive memories of nerve cells for
combinations lay behind the immense wisdom of the mind.
These memories were both inherited and acquired.
Intuition was the logical elimination routine, which
could instantly sift a single contextual answer from this
immense knowledge base. When you reached into your pocket
and identified a key, just by touch, you used this
process.
A
seamless pattern recognition process. So, the mind
received, at the input end, kaleidoscopic combinations of
millions of sensations. From these, it instantly
recognized objects and events. Recognized events
triggered contextual feelings. Feelings triggered allied
drives. Drives fired sequences of remembered muscle
movements. The circuit closed. 100 billion nerve cells
recognized events and delivered motor output, within a
bare span of 20 milliseconds. The time between the shadow
and the scream. All this was enabled by intuition and
massive neural memories. So, from input to output, the
mind was a seamless pattern recognition system.
Intelligent
drives. The current feeling dictated purpose at the
highest levels. A hierarchy of intelligences followed
through. At the second level, learned movements were
inserted. At the lowest level, fine motor coordination
delivered the final output whether a spoken word,
or a written line. A feeling expressed a purpose. A
feeling of fear could dictate an escape drive, whose
purpose was to achieve safety. That demanded instant
responses, varying across species. A deer bounded away. A
bird took flight. A fish swam off. While the activities
differed, they achieved the same objective of escaping.
Such activities could not be stupid. Escape was hardly
possible by heading into the predator. Increasing the
distance from danger demanded uncommon cleverness. That
objective could even be achieved by slipping into a safe
sanctuary, inaccessible to the predator. Like the
underside of a rock.. Creatively intelligent responses
occurred within fractions of a second. Purpose was
expressed as feelings at the highest level and
contextual, remembered drives delivered the final motor
outputs.
Largely
unconscious drives. The drive channel initially
learned by recording context. That was when you first
learned to drive a car. As the mind learned, combinations
of contextual memories were encoded into the memories of
drive channel neurons. Over the years, millions more
contexts would be added. Shortcuts, early lane changes,
responses to traffic snarls. Because the channel neurons
remembered and managed habitual activities, you were free
to worry about bills, on your drive home. Without
conscious management, the drive channel acted through
learned memories. But those memories also had inherited
components. It was these components, which responded to
feelings and emotions. These drives also acted at a
subconscious level.
The
historic basis of drives. Purposeful drives had
historic antecedents. The Hydra was a primeval example.
It was a branched tubular animal. A netlike arrangement
of neurons was interposed between its outside and its
internal digestive cavity. A stimulus applied to any part
of its body resulted in contraction or bending of its
tubular body and its tentacles. The Hydra moved about
with this simple nerve net, varied its length and used
its tentacles to push food particles into its mouth.
Occasional strong contractions of the whole animal served
to expel indigestible material from the same orifice.
From the beginnings of history, ongoing drives enabled
animals to move about, swallow, or expel food. Evolution
brought more sophisticated feelings and emotions,
generating a far wider range of drives. Drives to nurture
the young, to lie in the grass, or to play in the water.
But the essentials remained. Drives to seek out and
accept, or to avoid and escape.
The
agreeable quality. While complex mechanisms were used
to identify pain, or itching, why was the universal
experience of pain wretched and pleasure agreeable? What
kind of code could differentiate between nice and awful?
Medical texts reported on the pleasure emotion for rats.
The animals were observed when they were able to self
stimulate themselves, by pressing a lever, through
electrodes implanted in the septal area. They continued
pressing the lever till they were exhausted, preferring
the effect of stimulation to normally pleasurable
activities such as consuming food. The pleasure emotion
created a drive to repeatedly seek that stimulus.
And the
disagreeable quality. On the other hand, pain was
felt in two waves, separated by an interval of a few
tenths of a second. The first was sharp and localized.
The second wave was diffuse and still more disagreeable.
So, also, after an operation called lobotomy, the
presence of pain was no longer distressing to the patient
who would say that the pain was still there, but it did
not "hurt." Pain was divided into a sensation
and a disagreeable element. That element was, in reality,
a drive to avoid the stimulus.
Pleasant
and unpleasant drives. The primitive Hydra, moved
about, swallowed, or spewed out food. Its drives worked
to approach, accept, reject, or escape. Millenniums
later, the control systems were more sophisticated. But,
humans traveled the seas, enjoyed delicious meals and
occasionally became sea sick. Pleasant emotions generated
a drive to approach and accept. The rat kept pressing the
lever. Such emotions made you feel good. Unpleasant
emotions generated a drive to escape, or reject the
stimulus. The second wave of pain was a drive triggered
by cortical recognition of pain. That feeling triggered a
drive to escape. That drive was disagreeable. It made you
want to run away. When the drive was disconnected in
lobotomy, pain became just a sensation. Drives operated
at subconscious levels. When you want to reach out and
hug a child, or to hurry away from a gruesome sight,
remember, a subconscious drive is in charge.
