What goes into what we perceive as perception?

A Wide Angle Lens on Life & Biology

My guess is the chief inhibitor to unlocking a clear vision of what the multivariate factors are that drive our experience of life is largely due to the linear reductionist lens we tend to apply when looking at relational systems such as ourselves. Linear reductionist lenses are like using a black and white crayon in an attempt to render a full spectrum image. While it gives us information, some of it quite useful, there is a diminishing law of returns which turns to a negative rendering value after a certain point of inflection.

Linear, fixed focal point lenses are not capable of rendering a full understanding of the workings of complex adaptive systems since, for instance, there is no inherent beginning or end to a given system, but diffuse nested fields of interrelated influences. As a consequence of using unifocal lenses, we often become enchanted with the linear images produced through it, albeit we also become blind in a sense, because much of the rendering is a function of the lens and not an accurate representation of the relational landscape it is pointed toward.

If we apply a systemic relationship lens to biology for instance, we then see a porous increasingly diffuse nested set of influences between organisms rather than distinct isolated organisms separated by fixed membranes. There is a porous interdependent set of relational bonds that lead to the same unified whole which we can detect by picking any point in a system. For instance; we can see the connections between the atoms, organelles, cells, and organs inside our body, and this inward coherency then extends outward to the microbiome, the local environment, the larger ecosystem, planet, star system galaxy etc. all the way to the whole of the cosmos. Were we to pick any other point in that nested collection we could also trace it from that focal point to the nested fields of influences which define that point, and extend again to the whole as well. In effect, linear images are useful, but have their limits. Whenever we choose a focal point, we also sacrifice the larger context.

When we use a systemic relationship lens through which to look at the whole biological economy, we can see with greater depth into the larger biological body of life in which we live, and on which we depend. What defines our local experience in terms of stability or instability in the final analysis is more like a cultivated commitment of a parliamentary nature than any kind of sovereign relational theme. Coherency is built on the strength of serving mutual needs of nourishment and defense. Our experience is cultivated on the preponderance of relationships that are sometimes necessary, sometimes laced with compromise, but always that serve purposes in relation to adaptation โ€“ that of remaining a coherent by way of sufficient nourishment and defense as an entity over time in the context of the environment. We realize this threshold of “being” by way of finding and maintaining this coherent equilibrium in the context of the larger environment. We see things like our individual identity and group sociality built on this same engine of nested influences. Understanding this is both the key to maximal growth, and a sustainable equilibrium in relationship to the carrying capacity of the environment.

I could be missing something(s)

Here is an example of the diffuse bonds of influence that conspire to shape what we experience as life and being.

Biological Influences on Identity Being and Personality

The influences that conspire to define what we experience as things like identity, being and personality type are built on a deep ocean of context based relationships which we have only begun to see with any real clarity, much less harness to our advantage. The currents of influence on which we ride have yet to be captured by the meager net of abstractions we feebly waggle into the depths in hopes of capturing something of value. Here’s a look at one tiny portion of this vast ocean of opportunity we have yet to discover and settle by way of leveraging our understanding toward progress.

An Ancient Virus Lurking in Our Genes Could Play an Important Role in Some Addictions

“…An unusual version of a retrovirus nestled between genes involved in brain chemistry is more common in individuals with a drug dependency than the rest of the population.*

An Advance in Protecting the Brain from Dementia

Mitochondria is an organelle (tiny organ) inside our cells. One of the vital roles of it plays in the biological community is to produce a molecule we use as energy. It is like a central bank of our cells. It produces the currency by which things get done. The energy molecule is called ATP. (adenosine triphosphate) A loss of function in mitochondria can negatively impact our biological systems in a number of ways. ATP is not the only role of mitochondria. They also produce many other things by way of their own DNA. Among these biologically meaningful structures is a peptide called humanin.

Mitochondria communicate back to the cell and actively engage in determining major cellular policies in that larger context through signals communicated through structures like humanin. (these are called retrograde signals) Humanin, and many other signals are encoded in the nuclear genome of the organelle and play a crucial “voice in the choir” role in making sure the whole relationship economy functions. Humanin in particular plays a protector role in the cell against damage. (This is called a cytoprotective role). When the population of humanin, and other peptides that together provide for proper function of cells like ours (eukaryotic cells) becomes disproportionate the cellular needs, we suffer degradation of the systems we depend on. This can include dementia when it comes to brain function. Here’s a closer look at how the understanding of these roles can lead us to forming effective treatments.

Discovering Biological Friends and Foes

 

Not all viruses are dangerous. For instance; some are vital to how we function. The effects of endogenous retroviruses (those that stitch themselves into the human genome) are thought to have been essential for the evolutionary development of placental mammals as one example. Viruses can strategically trigger actions such as reproduction and, or go dormant depending on the biological climate at the time. The fact that cell replication in complex organisms like ourselves takes place and then goes dormant strategically may be due, at least in part, to the influence of viruses in the form of the genetic remnants of the traits that are now embedded in our genes. This, along with many other functions in human biology are parallel to, and could potentially be a result of, the influence of viral behaviors.

In addition to physiology, viruses are known to affect other behaviors such as those we categorize as psychological. The rabies virus is one well known virus that causes increased saliva flow and aggression in mammals. The borna disease virus can infect a number of animals, including humans. It has been known to cause hyperactivity, somnolence, depression and agitation. The point being; our experience as humans is built on a biological relationship economy that extends well beyond a stable set of genes. The relationship field from which we are composed can be cultivated, but it requires understanding how the whole process works. We have a long way to go, but we have made progress.

The spectrum of relationships in nature spans from constructive to destructive and that constructive vs. destructive trait depends on context. Some biological relationships contribute adaptive value, in these cases they are conserved. Viruses, like bacteria and so on can play destructive roles in the context of one system and a neutral or beneficial role in the context other systems. Like the role our various systems play from the respiratory system which carries nutrients in the form of oxygen to our cells, to the immune system which seeks out and destroys perceived antagonists, viruses also exist on this spectrum.. Some are lytic, in that they damage the relationship systems the host cell(s) depend on in such a way that the system is disrupted or destroyed. Understanding this destructive end of the biological spectrum, and how to remedy and or prevent these things from happening in the context of human systems is an important part of the further development of medicine. Here is a look at some of the work going on at the forefront of that discovery process:

“…Most people on the planet are thought to carry the HHV-6 virus, which doesnโ€™t cause symptoms in the majority of cases. Antibodies to the virus can be found in anywhere from 95 to 100 percent of healthy individuals, showing that most adults have become infected at some point. Itโ€™s thought to be harmless, but in people that have undergone organ transplant, take immunosuppressants, or get a chlamydia infection, the virus can become active… Two types of the virus exist; HHV-6B tends to infect infants and HHV-6A is usually asymptomatic. It does, however, integrate into cellular DNA, where it can remain for a lifetime. It has recently been suggested that the virus can reactivate and may play a role in a variety of diseases including depression, bipolar disorder, schizophrenia, or Alzheimer’s… This work indicates that some prescriptions drugs might be able to reactivate HHV-6, leading to life-threatening danger for the patient. It may be very useful to identify these cases early.”

The Relationship Engine that Defines Biology

 

If we step out of our structural model of โ€œorganismโ€ and โ€œgeneticsโ€ and look instead through a relational model that defines biology in general, we see a relationship climate in the biological landscape spectrum that spans from obligate (necessary) mutualism, through commensal relationships that benefit both parties, all the way to predatorily competitive where one benefits and the other is destroyed. Through this lens we begin to see the basis for the emergent intertwined systems we see in biology.

With this model a full spectrum of behaviors would happen in the context of a single organism for instance. Our own system has certain obligate mutualistic relationships such as that between our vital organs. We have commensal relationships with microbes that provide valuable services for the proper processing of food and get to flourish themselves as a result. We also have an immune system that predatorily looks for antagonists and seeks to destroy them.

Systems that align themselves around coherence through the acquisition and support of sustainable nourishment and defense of that coherence through the destruction, or compensation for antagonistic factors (pathogens) that are perceived to threaten that coherence. (Autoimmune diseases would be an example of a disproportionate response in this process)

This twofold relational axiom (Coherence and defense of coherence) is what defines adaptive biological systems. When we look through this coherence lens, the membrane that defines sustained coherence is not defined by genetics, or by the skin of any one organism, neither is it based on a singular organism. It is defined by an adaptive array of relationships across the spectrum that lend themselves to establishing and maintaining coherence. These various relationships are threaded through many organisms and sometimes only parts of other organisms which together define a single relational system.

A sustainable relational economy is one that is adapted to the environment with a proportional amount sampled from that full spectrum. In other words, nourishing coherence and defense of coherence is threaded through many creatures that form a collective body.

Here is an accidental discovery that happened to discover one of these defensive systems in plants which occurred when trying to study the effects of gravity on plants.

“…When plants are under attack… their defense systems are raised in other parts…. plants use the same signalling molecules that animals use in their nervous system… the signals as they travel in waves through plants in response to a stressor… there’s this systemic signalling system, and if you wound in one place the rest of the plant triggers its defense responses… if a plant gets wounded, an electrical charge fires, propagating across the plant. In animals, an excited nerve cell releases an amino acid called glutamate, which triggers a wave of electrically charged calcium ions that propagate to cells farther and farther away from the site… what happened to the plants is… Waves of light flow out from the source of the wound, spreading through the plant… once the wave hits, defensive hormones rise in that region of the plant.”

The Biological Community Defines Our Experience of Life

If we unpack the implications of the fact that a single celled parasite like Toxoplasma gondii can develop a strategy to modify mammalian neurophysiology and behaviors to suit its own biological ends, we can begin to appreciate the fact that the community of friends and foes in our local biological relationship field set the tone for what we experience as life.

There is a full spectrum of relationships that is possible in any given biological community that can span the spectrum from obligate (necessary) mutualism to parasitic and predatory relationship dynamics where seizing the fruit produced by other organisms is the core behavioral property of the organism.

Depending on the biological community’s bias toward cooperation involving mutual nourishment and common defense, or toward parasitic and predatory relational dynamics, the organism based community will tend toward homeostasis (balance), or instability. This makes whether or not we learn about, and act to appropriately tend the many organisms from which our local biology is composed is a key factor in whether balance or imbalance (health or disease) will happen. It also plays a key role in defining our identity and shaping experience of life. This makes understanding and cultivating the biological relational system we are part of a critical factor in effectively steering our experience of life.

Here is an article outlining howย a number of parasitic and predatory organisms press their agenda within the larger biological community. It is important to remember that there is a full spectrum of relationship possibilities, some of which bring nourishment, strength and health or defense of the integrity of the system against disruptive agents.

Biology Reveals Insights into Human Culture

This is an excellent documentary that illustrates how biological ecosystems find an equilibrium that is a suitable adaptive response to the environment. This means all the organisms that express nourishing and defense behaviors in a given ecosystem become specifically suited to the environment and each other. Islands are one of the places this biological balance is illustrated clearly; where the particulars of the environment along with the baseline biological ecosystem that inherited the island come to express a behavioral economy that is adaptive in that specific context. Islands with no large land predators may bring about flightless birds for instance because of the lack of need to fly away.

Christmas Island is an excellent illustration of how that biological equilibrium can be dramatically disrupted by a newcomer to the biological social economy. This disruption can expose weaknesses that are present because there was no need to build defenses against the strategies of the imported invader prior to its arrival. This is what drives biology’s own evolutionary expression of a “Game of Thrones” and may also be a good insight into the way the various human cultures evolved throughout the world – a reflection of populations finding equilibrium with the environment, reflecting its nature, coupled with the periodic need to adapt to “invaders” as we began to cross pollinate as a result of things like trade, climate shifts and so on, leading to the human version of “Game of Thrones”.

Powerful Influence from Small Changes

While this article is on *Brain Inflammation and Obesity* specifically, there seems to be a number of deeper implications if we apply a wide angle lens to the fact that certain infections, or microbiome populations, or traumas, etc. in the context of our complex biological system can shift behavioral expressions on more than physical scales. This influence on our relational landscape has a powerful influence on our experience of life. Extrapolated further we might begin to get a glimpse of how our evolution, history, culture and sense of identity might all be far more nebulous and arbitrary than we are used to believing.

The Language of Biology

Biology is a complex relational economy that produces coherent “meaning” in the form of structures and ongoing relationships that are aimed at specific goal oriented ends. Like verbal language and its capacity to produce the more complicated structures that are possible within its range of expression, like comedy or drama for instance, to accomplish the communication effectively requires certain contexts in order for them to work as intended. We see this same communication requirement in biology. Here’s an example of how that opportunity for a complex communication to convey something constructive or restorative can be destroyed by context:
