The Biochemicals of Emotions
article by Deborah Adler
Dr. Candace Pert, PhD, in her book Molecules of Emotions:
Why You Feel the Way You Feel, advances the concept of the human organism as a communications network, with emotions
functioning as the biochemical links between mind and body. In this process she redefines the nature of health and disease
and empowers the individual with responsibility – which we know can be reduced to its roots of “respond”
with the “ability” - to exert more control in their own lives.
significant that in the seventeenth century philosopher Rene Descartes, considered to be the founding father of modern medicine,
was forced into a deal with the Pope in order to obtain bodies for dissection. He had to agree to leave all matters of mind,
soul and emotions to the exclusive authority of the Church, claiming only the physical realm as his territory, thus
“dividing the human experience into two distinct and separate spheres that could never overlap.” This explains
the heretofore irreconcilable chasm between physical and psychological, emotional and spiritual disciplines, when in fact,
each is reliant upon the other if we are to treat the individual as an integrated whole.
machine and vessel we know as “Human” is a bio-chemical eco-system. “The molecules of emotion run every
system in our body….This communication system is in effect a demonstration of the bodymind’s intelligence, an
intelligence wise enough to seek wellness, and one that can potentially keep us healthy and disease free without the modern
high-tech medical intervention we now rely on.”
Dr. Pert defines emotions as “not only the familiar human experiences of anger, fear, and sadness, as well
as joy, contentment, and courage, but also basic sensations such as pleasure and pain, as well as the ‘drive states’
studied by the experimental psychologist, such as hunger and thirst.” These are recognized as measurable and observable
emotions and states. In addition, she also refers to a number of subjective experiences which are most likely unique to humans,
including “spiritual inspiration, awe, bliss, and other states of consciousness.”
Elmer Green of the Mayo
Clinic, pioneer in biofeedback to treat disease, said: “every change in the physiological state is accompanied by an
appropriate change in the mental emotional state, conscious or unconscious, and conversely, every change in the mental emotional
state, conscious or unconscious, is accompanied by an appropriate change in the physiological state.”
to Dr. Pert, it’s a simultaneous two-way street. She advances a new theory of information exchange “focused on
a purely chemical, nonsynaptic communication between cells.”
us consider the key players in the biochemistry of emotions; receptors, ligands, and peptides, and their definitions.
receptor is a single molecule “made up of proteins, tiny amino acids strung together in crumpled chains.” In the early 20th century, it was believed that in order for drugs to be
able to act in the body there had to be something present to which they could attach themselves. At that time “receptor”
was a hypothetical body component.
we recognize that receptor molecules respond to chemical and energy cues by vibrating. “They wiggle, shimmy, and even
hum as they bend and change from one shape to another.” They will dance
back and forth between two or three different configurations or favored shapes. They are always found attached to a cell in
the organism, either floating on the cell’s membrane or the oily outer membrane of the cell’s surface.
Pert offers the analogy of lily pads floating on a pond’s surface. Receptors, like the lilies, have their roots “enmeshed
in the fluid membrane snaking back and forth across it several times and reaching deep into the interior of the cell.” There may be millions of receptors on a typical neuron (nerve cell). They function
as sensors, or scanners – hovering in the cell’s membranes, dancing and vibrating, waiting to pick up messages
from other vibrating amino acids diffusing through the fluids surrounding each cell.
They cluster in the cellular membrane waiting for the right chemical keys to swim up into their keyholes – a
process known as binding.
Ligands (“that which binds” in Latin)
are the chemical keys that bind to the receptor, docking into their “keyholes,” then dancing and swaying they
create a disturbance to “tickle” the molecule into changing its shape and rearranging itself until there is the
proverbial “click” and information enters the cell.
can be a “natural or manmade substance which binds selectively to its own specific receptor on the surface of the cell.”
The dance between the ligand and receptor, in which the ligand bumps on and off, is the actual process of binding. It is through
this process – which produces a vibration - that allows the ligand to transfer its message to the receptor by way of
its molecular properties. Once the receptor has received the message, it transmits
it from the cell’s surface, deep into the cell’s interior. Here the state of the cell can change dramatically
through a chain reaction of biochemical events.
life of the cell, what it is up to at any moment, is determined by which receptors are on its surface, and whether those receptors
are occupied by ligands or not….The process of binding is very selective…Binding occurs as a result of receptor
specificity, meaning the receptor ignores all but the particular ligand that’s made to fit it…These minute physiological
phenomena at the cellular level can translate to large changes in behavior, physical activity, even mood.”
are three kinds of ligands: neurotransmitters, which carry information across the
gap, or synapse, between neurons; steroids, which are transformed into hormones
through a series of biochemical steps, and peptides, which comprise 95%
of all ligands. Made up of strings of amino acids, they play a wide role in regulating
practically all life processes.
“If we accept that peptides and other informational
substances are the biochemicals of emotion,” states Dr. Pert, “their distribution in the body’s nerves has
all kinds of significance...The body is the unconscious mind! Repressed traumas caused by overwhelming emotion can be stored
in a body part…there are almost infinite pathways for the conscious mind to access – and modify – the unconscious
mind and body.”
“Emotions and bodily sensations are thus intricately intertwined, in a bi-directional
network in which each can alter the other” – usually at an “unconscious" level, but under certain circumstances,
the process can surface into consciousness or “be brought into consciousness by intention.”
information goes through a filtering process as it travels across one or more synapses. This filtering process determines
what stimuli we pay attention to at any given moment by determining which sensory input reaches the areas of higher processes,
like the fontal lobes. Which sensory input enters our conscious awareness is determined by the quantity and quality of the
receptors, which can be influenced by a variety of things, including our experiences as a child, an event yesterday, even
what we ate at our last meal.
“Using neuropeptides as the cue, our
bodymind retrieves or represses emotions and behaviors. Dr. Eric Kandell and his associates at Columbia University College
of Physicians and Surgeons have proved that biochemical change wrought at the receptor level is the molecular basis of memory.
When a receptor is flooded with a ligand, it changes the cell membrane in such a way that the probability of an electrical
impulse traveling across the membrane where the receptor resides is facilitated or inhibited, thereafter affecting the choice
of neuronal circuitry that will be used. These recent discoveries are important for appreciating how memories are stored not
only in the brain, but in a psychosomatic network extending into the body, particularly in the ubiquitous receptors between
nerves and bundles of cell bodies called ganglia, which are distributed not just in and near the spinal cord, but all the
way out along pathways to internal organs and the very surface of our skin. The decision about what becomes a thought rising
to consciousness and what remains an undigested thought pattern buried at a deeper level in the body is mediated by the receptors.”
or emotional states, are a product of various neuropeptide ligands. When we experience an emotion or a feeling, there is a
simultaneous mechanism that activates a particular neuronal circuit.
to Dr. Pert, “there is no objective reality! In order for the brain not to be overwhelmed by the constant
deluge of sensory input,” some sort of filtering system must be in place to enable us to prioritize that information.
Thus we pay attention to what the bodymind deems most important and ignore the rest.
Because the receptors are not
stagnant, but constantly changing in their sensitivity and their arrangement with other proteins in the cell membrane, we
are not condemned to be “stuck” in a given emotional state. We have available to us at all times, the
“biochemical potential for change and growth.”
most of our bodymind attentional shifts are what Dr. Pert calls “subconscious” she states that we do have the
possibility of bringing some of these decisions into consciousness, and advocates doing so through use of various types of
intentional training or disciplines, such as meditation, breathing techniques, etc., that have been developed specifically
for the goal of increasing our consciousness.
In describing the role of peptides, Dr. Pert paints a wonderfully vivid
picture: “Peptides serve to weave the body’s organs and systems into a single web that reacts to both internal
and external environment changes with complex, subtly orchestrated responses. Peptides are the sheet music containing
the notes, phrases, and rhythms that allow the orchestra – your body – to play as an integrated entity. And the
music that results is the tone or feeling that you experience subjectively as your emotions.”
Dr. Pert emphasizes
an integrated system – a network – of information substances (referring to all the messenger molecules and their
receptors linking brain, body and behavior) – that facilitates communication in both directions. Now three previously separated areas: neuroscience, endocrinology, and immunology, with their corresponding organs – the brain; the
glands; and the spleen, bone marrow, and lymph nodes – have been joined together in a multidirectional network of communication,
linked by the information carriers known as neuropeptides.
Dr. Pert speculates that the mind is in actuality
the flow of information as it moves among the cells, organs, and systems of the body. Since one of the qualities of information
flow is that is can be unconscious, occurring below the level of awareness, we see it in operation at the autonomic, or involuntary,
level of our physiology. Thus the mind as we experience it may be considered immaterial, yet it has a physical substrate,
which is both the body and the brain. On the other hand, it may also be said to have a nonmaterial, nonphysical substrate
that has to do with the flow of that information. Therefore the mind is that which holds the
network together, often acting below our consciousness, “linking
and coordinating the major systems and their organs and cells in an intelligently orchestrated symphony of life. Thus, we
might refer to the whole system as a psychosomatic information network, linking psyche, which comprises all that is of an
ostensibly nonmaterial nature, such as mind, emotion, and soul to soma, which is the material world of molecules, cells, and
organs. Mind and body, psyche and soma.”
She refers to an intelligence that can be seen “running things,”
and references that intelligence, in the form of information running all the systems and creating behaviors, something certain
manipulative healers such as chiropractors relate to as the body’s wisdom, or “innate intelligence.”
Pert has become a bridge between and a synthesis of the scientific medical community and the non-traditional, non-allopathic
healing community. She has outlined an 8-Part Program for “Lifestyles of the Healthy, Whole, and Conscious” in
her book, Molecules of Emotions, providing some common sense keys to ongoing, daily, emotional self-care.
“Emotions are a key element in self-care because they allow us to enter into the bodymind’s
conversation. By getting in touch with our emotions, both by listening to them and by directing them through the psychosomatic
network, we gain access to the healing wisdom that is everyone’s natural biological right.”
How do we achieve this? First we must acknowledge and claim all our feelings – not just the
“so-called positive ones.” Anger, grief and fear are experiences that are actually vital for our survival. Anger helps us define boundaries; grief helps us deal with losses; and fear protects
us from danger. These only become toxic when we deny these feelings, so that
they cannot be easily and rapidly processed through the system to be released. Ultimately, the more we deny, the greater toxicity
we allow, often setting up an explosive release that can be harmful to ourselves or others.
“The goal is to keep information flowing, feedback systems working, and natural balance maintained,
all of which we can help to achieve by a conscious decision to enter into the bodymind’s conversation.”
Dr. Pert offers the following ways to use awareness and intention to tap into the psychosomatic network,
“in order to prevent disease and maximize health.” The real key is
taking responsibility for the way we feel. It is time to recognize that our external world is simply a reflection of our beliefs
To be fully conscious involves awareness of our mental, emotional and even basic physical experiences. The more
conscious we are, the more we can tune into the conversation going on at the autonomic or subconscious levels of our bodymind. When we can enter into these levels where basic functions such as breathing, digestion,
pain control, immunity and blood flow are carried out, then we can use our awareness to enhance the effectiveness of the autonomic
system by dialoging with it. For it is in this system “where health and disease are being determined minute by minute.”
Accessing the Psychosomatic Network
It is possible to access the psychosomatic network and enter the bodymind’s conversation to redirect it.
“By learning to bring your awareness to past experiences and conditioning – memories stored in the very receptors
of your cells – you can release yourself from these blocks.” She suggests using assistance for long-term blockages
including hypnotherapy, touch therapies, personal –growth seminars, meditation and prayer. The goal is to learn to respond
to what is actually occurring in the present, which is “what consciousness is all about.”
Tapping Into Your Dreams
“Develop the daily habit of recalling and transcribing your dreams. Dreams are direct messages from your
bodymind…Becoming aware of your dreams is a way of eavesdropping on the conversation that is going on between your psyche
and soma, body and mind.” This facilitates obtaining valuable information
and also gives us the ability to intervene, if needed, in order to make appropriate changes in our behavior and psychology.
FOUR: Getting in Touch With Your Body
The skin, the spinal cord, the organs, are all nodal points of entry into the psychosomatic network. Some great methods? Take a walk. Run. Get a massage, a spinal adjustment, or lots of good hugs!
FIVE: Reducing Stress
Dr. Pert recommends meditation, “because it allows us, even without conscious awareness, to release emotions
that are stuck in modes that subvert a healthy mind-body flow of biochemicals.
The value of exercise is not so much muscle building or burning calories, as it has to do with getting the heart
to pump faster and more efficiently, thus increasing blood flow to nourish and cleanse the brain and all our organs.
Ways to help enhance the communication flow throughout bodymind while walking: “I let the opposite hand
swing forward with each step as I walk, without music. Somehow this sets left-brain-right-brain information flowing, breaking
up old patterns of worry and rumination.”
Because of its survival value, eating “has been wisely designed
by evolution to be a highly emotional event….There are at least twenty different emotion-laden peptides released by
the pancreas to regulate the assimilation and storage of nutrients, all carrying information about satiety and hunger.” Ignoring this information can lead to using food to bury emotions resulting in nervous
eating, depression eating and other behaviors.
We can develop the ability to know what our body needs in the way of nourishment, and when, by tuning into our
emotions as information about the digestive process.
Environment can influence the emotional experience of eating. Dr.
Pert recommends a peaceful stress-free environment.
Eating in full consciousness of the tastes and textures; acknowledging the gift of the food through a prayer or
blessing is seen as an act of consciousness rather than a religious ritual.
(In many indigenous cultures people acknowledge and express appreciation and respect for the sacrifice that has
been made by the food. Eating is regarded as nurturing and loving the physical body, or “altar,” which is also
an act of appreciation.)
She advises to avoid Sugar, which Dr. Pert considers to be “a drug, a highly
purified plant product that can become addictive.” We need to look at sugar
as a drug whose chronic effects rank right in there with more acknowledged “drugs of abuse.” When sucrose is converted into glucose, “a key metabolic regulator of your bodymind,” it acts
upon the glucose receptors which regulate the release of insulin and other neuropeptides from the pancreas. This chemical
reaction can drastically alter how we feel as well as how we metabolize our food.
All drugs can alter the natural flow of our body’s own “feel-good” peptides. “What causes
people to consume legal and illegal drugs …I believe – is emotions that are unhealed, cut off, not processed and
integrated or released.” Rather than process and heal the unwanted “stuck” feelings, we reach for a way
to anesthetize ourselves. Self-dialoging to find the source of the emotions,
finding ways to process them, some form of exercise can shift our mood and give us time to make different choices.
Finally, we want to live in such as way that promotes a feeling of “belonging,
loving kindness and forgiveness.” In order for us to be healthy we have
to cultivate the proper paradigm. We can achieve wellness by trusting our bodymind’s ability and desire to heal and
