Neuroscience—the science of the brain and its complex pathways—is no longer just about understanding brain injuries or diseases. It is fast emerging as the key to decoding human happiness, motivation, decision-making, and emotional health. Every thought you think, every emotion you feel, and every choice you make triggers the release of neurochemicals that directly influence your physical health and mental well-being.
What is Neuroscience?
At its core, neuroscience is the study of the brain and nervous system. It examines how neural activity translates into behavior, emotions, and bodily functions. It also explores how the release of neurotransmitters—the brain’s chemical messengers—affects our daily lives.
Every time you experience joy, stress, excitement, or anxiety, your brain responds by releasing specific chemicals. These include:
- Dopamine – motivation and reward
- Serotonin – mood and happiness
- Oxytocin – love and bonding
- Endorphins – pleasure and pain relief
- Cortisol – stress response
The Brain-Heart Conflict
Modern neuroscience reveals a critical conflict between the analytical mind and the intuitive heart. While the brain calculates, analyzes, and reacts with speed, the heart feels, loves, and operates on emotional intelligence. However, the brain’s hyperactivity—especially under stress—can overpower the calm rhythms of the heart.
Just like a lightbulb bursts with excess electricity, the body too can crash under emotional overload, often leading to cardiac arrests or sudden strokes. These events are not just physiological; they’re deeply tied to emotional and neural stress.
To manage this overload, heart health specialists recommend methods to reduce cardiac exertion, such as using antioxidants like vitamin E to regulate overactive heartbeats. However, the real preventive medicine lies in emotional self-regulation—keeping stress hormones like cortisol in check.
Healing the Heart, Then the Brain
Once heart function is stabilized, the next battleground is the brain under emotional pressure. A brain flooded with cortisol may become reactive, impulsive, and drained. The antidote lies in consciously fostering a mental environment that releases more of the “happy hormones”—dopamine, oxytocin, serotonin, and endorphins.
This is where emotional awareness and mental discipline become vital.
Internal Dominant Focus (IDF): Your Emotional Compass
The concept of Internal Dominant Focus (IDF) helps individuals assess whether they are primarily focused on positivity or stress. It is easy to detect:
- If your inner self feels calm, authentic, and uplifted, your IDF is likely positive.
- If you feel tense, irritable, or drained despite outward attempts at cheerfulness, your IDF is likely negative.
In such cases, detachment is the first step—emotionally stepping back from the situation before transitioning into true positivity. This is a step-by-step process that rewires neural circuits over time, supported by the science of neuroplasticity.
Positivity vs. Mindfulness: What Impacts Happiness More?
In a recent statistical study conducted by the author (Swati Rao Shiv), striking results emerged about what truly enhances human happiness:
- A 1-unit increase in positivity led to a 51% rise in happiness.
- A 1-unit increase in mindfulness resulted in a 19% increase in happiness.
- Comparatively, even a 1-unit increase in income showed only a 17% increase in happiness, regardless of whether the income was low, medium, or high.
These results emphasize that mental orientation—particularly toward positive thoughts and emotional awareness—has a far stronger impact on happiness than financial gains.

Future Directions: Connecting Thoughts to Chemicals
What lies ahead for neuroscience is not just recovery after disease—but preventive emotional medicine. There’s an urgent need to help people become aware of how their thoughts influence neurochemical patterns, and how small changes in thinking can significantly improve well-being and even increase lifespan by up to 50%.
By learning to rewire our brains through intentional focus on positive emotions, mindfulness, and self-regulation, we can reclaim control over our health and happiness—starting now, from within.
