The neurochemical work of the brain provides many arguments that question or even refute the concept of the soul as an immaterial entity independent of physiological processes. First, all mental processes, including consciousness, emotions, and decision-making, have a clear neurochemical basis. For example, neurotransmitters such as dopamine, serotonin, and glutamate directly affect our mood, motivation, and perception of reality. Damage or imbalance of these substances leads to personality changes, depression, hallucinations, or memory loss, which indicates that "personality" and "consciousness" are products of the brain, and not manifestations of an immaterial soul.
Secondly, experiments with electrical stimulation of the brain (for example, the work of Wilder Penfield) show that artificial exposure to certain areas can evoke memories, emotions, or even religious experiences. If the soul were independent of the brain, such manipulations would not have such an effect. Moreover, in clinical death, when the brain stops receiving oxygen, consciousness turns off almost instantly, and "near-death experiences" are explained by hypoxia and the release of endorphins, rather than the exit of the soul from the body.
Thirdly, evolutionary biology shows that consciousness developed gradually as an adaptive mechanism, rather than being "injected" into humans in a supernatural way. Primitive animals with less complex brains show the beginnings of consciousness, emotion, and learning, which contradicts the idea of an exclusively human soul. If there were a soul, it would either have to be absent in animals or manifest itself in some material way, but there is no evidence of this.
Finally, the phenomenon of split brain (when the severing of the corpus callosum leads to the emergence of "two consciousnesses" in one body) it calls into question the unity of the soul. How can one soul split into two independent streams of consciousness? All these data indicate that the "soul" is just a metaphor for complex neurochemical processes, and not an independent substance.
Logically speaking, there is a neurochemical brain function that completely negates the soul, and which has been proven. She denies it as follows:

How can one soul split into two independent streams of consciousness? All these data indicate that the "soul" is just a metaphor for complex neurochemical processes, and not an independent substance.
