It is said that when a person dies, his soul takes 17 days to overcome and leave the earth’s electromagnetic field forever, and it is also said that the relatives of the deceased continue to feel the proximity of the deceased within the same time, to receive clear and reassuring signals about his presence. According to popular beliefs, the soul of a deceased person goes to heaven, paradise, purgatory or hell 40 days after death, and until that time his spirit floats and remains among his loved ones on earth. The Russian scientist Garjaiev was the first to experiment with this space-time, with light in a vacuum chamber, a variable spectrum laser capable of modeling itself on DNA samples and reproducing, although in a different way, like a hologram, the image of the human soul, defined as the “ghost effect”, and the laser continues to record the ghost of the deceased for 40 days after death.
The soul is still a mystery of interest to most religious and philosophical cultures, it is the object of the most different speculations, it is considered a continuation of life in the form of a spirit, often defined as immortal, and although it is an invisible entity, someone, such as Duncan MacDougall, has even tried to weigh it with a famous experiment, relating it to the weight of 21 grams that a terminal patient loses immediately after the last breath, when the soul is thought to leave the body in which it resides throughout its earthly life.
But for science, the problem of the soul does not arise at all, because for science, it does not exist at all, neither as it was understood in the past, ethereal, intangible and imperishable, nor as an empirical or otherworldly spirit, because for science itself the soul is a neurobiological product, it does not come from the depths of the heart, but from the dark subcortical regions of the brain, that is, from the brain circuits where consciousness arises and dies at the same time as it, when the heart stops along with the vital organs with the entire physical substrate, including the brain.
Therefore, scientifically, the soul is an abstract and real emotion that manifests itself from the depths of our thinking organs, it already exists at the moment of birth, but it is not an inanimate, independent and solitary entity, because biologically it goes hand in hand with consciousness, and based on chemical structure and phenomenology, the soul is inherent in all mammals and most vertebrates, that is, in all animals like us.
Therefore, for science, the soul originates from the working of the brain mechanisms of living beings, is linked to the psychological dimensions it generates, and changes depending on the period in which a person lives, often filling a void, which the mind, rationality and intelligence cannot fill. Yet the soul of each of us is an invisible and impractical presence, which constantly speaks to us in the depths of our conscience, making us rejoice or suffer, and because it is invisible, without organic mass, or rather not organized as an organ, it is also incurable in the pain it causes, one of the most intense and heartbreaking, such as occurs at the end of an important love or coincides with an inevitable loss. In fact, science, skeptical of its existence, has not been able to produce a cure for mental pain, that intense and unbearable pain that explodes in despair, in the most difficult moments of life, which produces depression, which is also random and very difficult to cure, and since it is assumed that the emotions of the soul are generated by brain circuits, doctors all over the world usually try to numb that elusive and inevitable pain with psychotropic drugs, to weaken negative emotions, to calm suffering or to quell worsening discomfort.
But the soul never remains silent, it continues to speak to us in our moments of choice and important decisions, engaging and strengthening our instincts to guide us, to comfort us intimately or reproach us when we are frustrated, disappointed or demotivated, and always radiates a vital spirit that nourishes it, making its presence felt strongly.
The brain is considered the organ responsible for perception, memory, feelings, morality, personal identity, knowledge, thinking, intelligence, rationality, and even instinct, and current neuroscientific studies that question human interiority, containing drives, ambitions, personality and essence, consider the soul to be merely an echo of consciousness and the brain’s level of connectivity, unique and different for each human, as there are no two identical brains even in monochorionic twins.
But is it true that everything can be traced back to the brain and is it possible to explain the soul only in terms of the brain? In reality, all theories have proven inadequate in explaining how the different mechanisms of nerve centers and the workings of their molecules can be traced back to brain activity alone, and these theories have never completely compromised the human version of soul and body, because the attempt to separate the two actually strengthens the concept of the soul, which we all feel we possess and store in our body or bodies.
our brain, the vital breath that animates us and has its own “weight”, although immaterial, in human existence, an enigma that continues to fascinate, and continues to exist, beyond all scientific certainty.
