Have you ever stopped to consider how the things you do today might shape the destinies of your future generations, and no, I’m not talking about climate change?
My father would often tell me how his mother would purchase a whole basket of fruits or candies from a street vendor and then distribute them to the neighborhood kids for free. It was a simple act of kindness that probably left a lasting impression on many. While there’s this spiritual concept of karma, that’s not what I wish to talk about either.
Instead, let’s take a scientific dive and explore a little into the realms of neuroscience and genetics that may provide us some clues to the relationship between our experiences, memories, and our DNA.
Throughout our lives, we make decisions—some seemingly insignificant, others pregnant with highly charged emotions. These decisions set off a chain of events, with stronger emotions leading to more long-term and strongly etched memories of these events in our minds. But how does this affect the lives of our future generations?
During emotionally charged events, our brains release neurotransmitters like dopamine and serotonin. These chemicals not only affect our immediate reactions but also penetrate the nucleus of our brain cells. There, they interact with core proteins called histones, initiating a cascade of epigenetic modifications. This intricate process, known as epigenetics, entails changes to the genome that regulate gene expression.
Traditionally, memories have been understood as synaptic connections—the wiring of our brains. However, recent discoveries suggest a deeper complexity. Yes, memories still involve connections, but beneath the surface, changes can occur at the level of DNA, which we also pass on to our offspring.
It’s crucial to recognize that the impact extends beyond individual family lineages & societies —it encompasses humanity as a whole. We’re all interconnected, constantly shaping experiences that leave impressions on young minds. Recognizing that our actions today have far-reaching consequences beyond our own imagination and lifetimes not only makes me feel more responsible for my actions but also inspires me to leave this world with more positivity and empathy.
What I have shared here is just my understanding and is definitely not coming from a place of authority on any subject. Feel free to share your thoughts or correct me if I am wrong. I’m always open to learning and growing.
