This Week We Learn About The Brain And The Nervous System As We Lear This week we learn about the brain and the nervous system. As we learn about how chemical reactions affect us, it made me think of a question. Do we truly control our actions and behaviors? Or do we act based solely on the chemical reactions that happen in brains and nervous systems? What do you think? Which is it? Free will or chemical reactions? In your discussion post, which option do you agree with? Support your response with information from either our textbook or from the video below.
Paper For Above instruction The relationship between free will and chemical reactions in the brain and nervous system is a profound philosophical and scientific debate that has engaged scholars for centuries. Recent advances in neuroscience suggest that our behaviors, thoughts, and emotions are deeply influenced by neurochemical processes, raising questions about the extent of our free will. This essay explores whether human actions are primarily governed by autonomous decision-making or are the result of biochemical reactions within the brain, drawing on contemporary research from neuroscience and psychology. The human brain, a complex organ composed of billions of neurons, functions largely through electrical and chemical signals. Neurotransmitters such as dopamine, serotonin, and norepinephrine play critical roles in regulating mood, motivation, and behavior (Kandel et al., 2013). For example, dopamine is associated with reward processing, influencing our tendency to seek pleasurable experiences. These neurochemical processes operate automatically and often below conscious awareness, suggesting that much of our behavior could be driven by biochemical reactions rather than a conscious exercise of free will (Eagleman, 2011). Supporters of the view that our actions are primarily influenced by chemical reactions argue that neurobiological evidence indicates that decisions are the result of complex brain chemistry and neural firing patterns. For instance, studies have demonstrated that manipulating neurotransmitter levels can alter mood, impulsivity, and even decision-making processes (O’Connor et al., 2018). This indicates that many behaviors we perceive as voluntary are, in fact, modulated or constrained by biochemical states, undermining notions of complete free agency. On the other hand, proponents of free will maintain that humans possess the capacity for autonomous decision-making, despite the influence of neurochemical processes. They argue that while brain chemistry influences behavior, it does not eliminate the possibility of conscious control. The human capacity for
