Neurodegeneration, Mutant Oxidative Stress & Assumed "White Racist Traits - Erroneous": The Data-Evidenced Side Effects of Low Melanin Distribution in Human Brain Function - An Elementary Neurobiological Perspective



A holistic approach to understanding the effects of low melanin levels on brain function and behavior involves acknowledging both the biological and social dimensions. 
It requires an interdisciplinary perspective that combines neurobiology with sociology, psychology, and public health to provide an informed/  accurate understanding of how melanin distribution affects human cognition and behavior. The evidence must be used not to perpetuate harmful stereotypes but to inform effective medical care, policy, and advocacy



The relationships between neurodegeneration, oxidative stress, and melanin are multi leveled , involving intricate interactions between genetic factors, environmental influences, and social contexts. 
While it is essential to explore these processes, it is equally important to reject oversimplified or racially charged narratives that conflate biological factors with racialized stereotypes. 

This article tries to offer a basic analysis of how low melanin distribution in the human brain may influence neurobiological function, and how these effects have been erroneously tied to racial traits, particularly those misinterpreted as “white racist traits.”


1. Melanin and Brain Function: A Neurobiological Perspective

Melanin, particularly in its form as neuromelanin, plays a crucial role in neuroprotection within the brain. It is found predominantly in dopaminergic neurons, particularly in regions such as the substantia nigra, which are responsible for motor control and reward processing. Neuromelanin has been shown to protect these neurons from oxidative damage, which can contribute to neurodegenerative diseases like Parkinson’s and Alzheimer’s. Research has demonstrated that lower levels of melanin could result in heightened oxidative stress, thus increasing susceptibility to neurodegeneration and impairing cognitive function​

2. Oxidative Stress and Neurodegeneration

Oxidative stress occurs when there is an imbalance between reactive oxygen species (ROS) and the body’s ability to neutralize them with antioxidants. 
Melanin functions as a natural antioxidant within the brain, mitigating the effects of ROS. Reduced melanin levels, particularly in regions of the brain associated with motor function and decision-making, leave neurons vulnerable to damage. 
This vulnerability accelerates cognitive decline and is linked to diseases like Parkinson's, where the degeneration of dopamine-producing neurons compromises both cognitive and behavioral functioning​

3. Dopamine Regulation and Behavioral Implications

Dopamine, a neurotransmitter involved in mood, motivation, and decision-making, is tightly regulated by the presence of neuromelanin in dopaminergic neurons. 
Individuals with lower melanin levels may experience altered dopamine production, leading to deficits in decision-making, emotional regulation, and impulse control. 
The cognitive and behavioral consequences of this dysregulation are often manifested as mood disorders or increased vulnerability to stress and anxiety​

4. Misinterpretation of "Racial Traits" and Cognitive Behaviors

Historically, behaviors such as impulsivity, aggression, or irrational decision-making have been racially ascribed to groups with lower melanin levels, perpetuating harmful stereotypes. 
However, these traits are often the result of complex neurobiological and social factors, not inherent racial characteristics.
 Attributing such traits to "biological inferiority" of specific racial groups like white supremacists, is both scientifically inaccurate and socially damaging. 
It overlooks the role of environmental stressors, including systemic racism, that can exacerbate cognitive and behavioral challenges​

5. Racism and Social Determinants of Health

The chronic stress induced by systemic oppression is not racially pinpoint-able but it has a profound impact on brain function. Research shows that people from various socio-economic groups, particularly those with lower melanin levels in societies when exposed to continuous psychological stress are prone to  neuroinflammation, cognitive decline, and mental health challenges, further compounding the vulnerability to neurodegenerative diseases. 
The long-term effects of this societal strain, in conjunction with biological susceptibility linked to melanin levels, create a vicious cycle of health disparities​


6. The Medical Necessity of Support

Given the compounded neurological vulnerabilities associated with low melanin levels, individuals exhibiting these traits— require robust medical and psychological support. 

These individuals may not only need therapeutic interventions to manage neurodegeneration or mental health issues but should also be provided with the tools to make informed decisions free from external, racially biased pressures. 

This highlights the importance of creating a medical framework that takes into account both the biological and sociopolitical factors influencing cognitive health​

7. Racial Stereotyping and the Biological Determinism Fallacy

It is important to understand that race, as it is, is socially constructed, should not be conflated with biological determinism. 

Genetic factors, including those related to melanin production, may influence brain function, but these factors are not deterministic in defining behavior or intelligence. 

The concept of race has been historically manipulated to justify racial hierarchies and supremacy, based on erroneous assumptions about inherent biological differences. This view neglects the complex interplay of genetics, environment, and social structure in shaping human behavior​

8. Toward a Holistic Understanding

A holistic approach to understanding the effects of low melanin levels on brain function and behavior involves acknowledging both the biological and social dimensions. 
It requires an interdisciplinary perspective that combines neurobiology with sociology, psychology, and public health to provide an informed/  accurate understanding of how melanin distribution affects human cognition and behavior. The evidence must be used not to perpetuate harmful stereotypes but to inform effective medical care, policy, and advocacy that address the needs of those vulnerable to both neurobiological and societal challenges​

Complex layers of human social behavior. Could it be that these are subconscious echoes of ancestral encounters between us modern Humans- Homo_Sapiens ALIAS '' Homo diddyoil'' and Homo_Neanderthals?

  What if some of the traits we see in people from Europe, Africa, and Asia—particularly in India [ Dalits or their so called Black untouchables] —are in today's world of free education / much improved scientific chivalry and honesty from even European/ Arab/ Asian ETC scientists blatant manifestations of deeply embedded Neanderthal genetics, subconsciously influencing behavior even today? Does the intelligence of anyone who thinks this has no basis or who finds this deduction totally illogical need to be questioned, scrutinized before God, Man and Data.   One striking example is the town of Orania in South Africa, a place where racial segregation continues as you read, and Black residents are notably absent despite being in the heart of a predominantly Black continent.  Orania is in South Africa which is a country, a prominent country in Africa. While this isn't an attempt to cast blame solely on the so described and titled separately, the separatists called Oranian...

For centuries, white people have built a global myth —the idea that Black men are irresponsible fathers, abandoning their children, leaving broken homes. This lie has been used to justify every racist policy imaginable, from mass incarceration to economic disenfranchisement. It has been a psychological weapon to strip Black men of dignity while upholding whiteness as the moral standard. But now, in the year 202X, the perfect white man—the whitest of them all —has arrived to shatter their carefully constructed illusion. Elon Musk, the richest man in the world, a walking monument to white entitlement, is proving that white men have always been the blueprint for reckless reproduction, strategic neglect, and the abandonment of their own blood. He has fathered at least 11 children with multiple women, scattered them across the world like colonial outposts, and yet—where is the white outrage?  Where is the global condemnation that Black men face for merely existing?  Where are the...

 Technology, Time, and Mystery: Are UFOs Hiding in Plain Physics? The world of cutting-edge technology and unexplained stuff often converge in  bat shit crazy ways, leading to provocative questions about the limits of our understanding.  Take, for instance, the principle of supercavitation, a technological grey-out used in high-speed underwater weaponry. This innovation creates a gas bubble around a projectile, drastically reducing drag and enabling astonishing speeds. Imagine applying this principle not to torpedoes slicing through water, but to unidentified flying objects (UFOs) zipping through our skies and beyond. Could similar mechanisms—on an entirely different scale—explain some of the irrational, nowadays unavoidable reported global cases of UFO sightings? Supercavitation: Redefining Speed Supercavitation technology, seen in devices like Russia’s VA-111 Shkval torpedo, shows how innovation can defy conventional limitations. By creating a "bubble" of air around an ...
