Phobias may be memories passed down in genes from ancestors
Memories may be passed down through generations in DNA in a process that may be the underlying cause of phobias
Memories can be passed down to later generations through genetic switches that allow offspring to inherit the experience of their ancestors, according to new research that may explain how phobias can develop. Scientists have long assumed that memories and learned experiences built up during a lifetime must be passed on by teaching later generations or through personal experience. However, new research has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. Researchers at the Emory University School of Medicine, in Atlanta, found that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations. The results may help to explain why people suffer from seemingly irrational phobias – it may be based on the inherited experiences of their ancestors.

i would love to know what this means in the context of slave descendants.
Yes, me as well, and also what this means for surviving families of not just enslavement, but also Indigenous genocide, and in some cases, both simultaneously. We have our great grandmothers memories. For some of us, this inherently means trauma. I have heard of a book called “Post Traumatic Slave Syndrome” but as far as I’m aware this is just that, and not peer reviewed.
However, I think we’ll come to find that this will play a huge role in the way we shape and form academia in the future. As it becomes clear that anything from multi-generational wariness to European-looking people to fears of water or possibly even animals used to enforce enslavement can be explored as a genetic memory… Maybe those atrocities themselves will no longer be forced under the rug.
There is a systematic downplaying of colonial history; to the point where people don’t even know what land they stand on or who it originally belongs to. However, for the descendants, even if they are forced out of their own histories and cultures, they will STILL carry some form of memory of these decades/centuries long traumas. It will affect them throughout their lives and they may not even know it… I often see this now in the form of all-to-regular self hatred.
When it is empirically proven that the descendants of the enslaved and survivors of genocide carry a genetic memory, maybe the colonizer’s academic structure will force itself to honor those it constantly erases. Or maybe it will simply shape itself again to continue on how it already does; as active agents of social violence.
In an emotionally charged talk, MacArthur-winning activist Majora Carter details her fight for environmental justice in the South Bronx — and shows how minority neighborhoods suffer most from flawed urban policy.
"Environmental justice, for those of you who may not be familiar with the term goes something like this: No community should be saddled with more environmental burdens and less environmental benefits than any other. Unfortunately, race and class are extremely reliable indicators as to where one might find the good stuff, like parks and trees, and where one might find bad stuff, like power plants and waste facilities. As a Black person in America, I am twice as likely as a white person to live in an area where air pollution poses the greatest risk to my health. I am five times more likely to live within walking distance of a power plant or a chemical facility, which I do. These land use decisions created the hostile conditions that lead to problems like obesity, diabetes and asthma. Why would someone leave their home to go for a brisk walk in a toxic neighborhood?”
Childhood poverty and chronic stress may lead to problems regulating emotions as an adult, according to research published online in the Proceedings of the National Academy of Sciences.
"Our findings suggest that the stress-burden of growing up poor may be an underlying mechanism that accounts for the relationship between poverty as a child and how well your brain works as an adult," said Dr. K. Luan Phan, professor of psychiatry at University of Illinois at Chicago College of Medicine and senior author of the study.
The study was conducted by researchers at UIC, Cornell University, University of Michigan and University of Denver.
The researchers found that test subjects who had lower family incomes at age 9 exhibited, as adults, greater activity in the amygdala, an area in the brain known for its role in fear and other negative emotions. These individuals showed less activity in areas of the prefrontal cortex, an area in the brain thought to regulate negative emotion.
Amygdala and prefrontal cortex dysfunction has been associated with mood disorders including depression, anxiety, impulsive aggression and substance abuse, according to the authors.
Phan said it is well known that the negative effects of poverty can set up “a cascade of increasing risk factors” for children to develop physical and psychological problems as an adult. But it has not been known how childhood poverty might affect brain function, particularly in emotional regulation. The ability to regulate negative emotions can provide protection against the physical and psychological health consequences of acute and chronic stress, he said.
The study examined associations between childhood poverty at age 9, exposure to chronic stressors during childhood, and neural activity in areas of the brain involved in emotional regulation at age 24.
The 49 participants were part of a longitudinal study of childhood poverty. Data on family income, stressor exposures, physiological stress responses, socio-emotional development, and parent-child interactions were collected. About half the participants were from low-income families.
Using functional magnetic resonance imaging, the researchers evaluated the participants’ brain activity as they performed an emotional-regulation task. Subjects were asked to try to suppress negative emotions while viewing pictures, using a cognitive coping strategy.
"This serves as a brain-behavioral index of a person’s day-to-day ability to cope with stress and negative emotions as they encounter them," Phan said.
Perhaps the most important finding, Phan said, was that the amount of chronic stress from childhood through adolescence—such as substandard housing, crowding, noise, and social stressors like family turmoil, violence or family separation—determined the relationship between childhood poverty and prefrontal brain function during emotional regulation.
