Understanding the Brain's Role in Shaping Your Identity
Written on
Chapter 1: The Emotion-Generating Organ
The brain, a three-pound marvel infused with your joys and sorrows, plays a pivotal role in crafting your emotions and shaping your identity. In this exploration, we will delve into how the brain influences who you are.
I have a profound appreciation for books written by esteemed neuroscientists and psychologists, particularly those that present complex ideas in accessible terms for non-specialists. This article draws from two significant works: "The Brain: The Story of You" by David Eagleman and "How Emotions Are Made: The Secret Life of the Brain" by Lisa Feldman Barrett.
This is not a rigorous lecture on neuroscience; rather, it unfolds like a narrative.
Our thoughts, dreams, memories, and experiences stem from a peculiar neural substance. The essence of our being resides in the intricate patterns of electrochemical signals within our brains. When these patterns cease, so do we. A transformation in this activity, whether due to injury or substances, can also alter our very character. — Eagleman, David. The Brain: The Story of You (p. 5)
Let's delve into the workings of our brains and their influence on our identities.
Our Brains: Adaptable and Not Preordained
The wiring of the human brain is not predetermined; rather, genes provide broad guidelines for the formation of neural networks, while life experiences fine-tune this wiring, enabling adaptation to our environment.
Human infants require years to develop fully, unlike many other mammals that are born with innate capabilities, such as walking or swimming. This extended development process may seem disadvantageous, but it actually grants humans a remarkable adaptability.
Eagleman illustrates this with the example of a rhinoceros placed in New York City, which would struggle to survive. Similarly, a giraffe in the Arctic would face insurmountable challenges. In contrast, humans can adjust to a multitude of environments, thriving even in adversity. Take, for instance, the resilience of individuals in Gaza, who endure the hardships of war yet maintain their faith and strength.
The human brain's capacity to adjust to its surroundings has enabled our species to dominate diverse ecosystems and even extend our reach into the cosmos. — Eagleman, David. The Brain: The Story of You
Emotional Understanding
Barrett presents two distinct theories regarding the origin of emotions:
- Classical Theory: Proposes the existence of "universal emotions" such as sadness, fear, anger, and happiness. This viewpoint is often reflected in popular media representations, like those found in films such as "Inside Out."
- Emotion Construction Theory: This more nuanced approach argues that emotions are not innate. Instead, they are constructed based on individual upbringing, environmental influences, and cultural contexts. Barrett contends that there is substantial research highlighting deficiencies in the classical theory, and the construction theory offers a more comprehensive understanding of emotions.
Barrett acknowledges that while this perspective may initially seem counterintuitive, a deeper examination reveals its validity. (I intend to explore this theory further in a future article.)
Our Upbringing and Its Impact
Eagleman notes that the formative years from birth to age 21 significantly shape our personalities. Our experiences, habits, and upbringing during this period influence who we become as adults.
Childhood Development
Our brains form connections by establishing synapses, which act as pathways between neurons. If these pathways are not utilized, they will eventually deteriorate, emphasizing that our identities are shaped not only by what is developed in our brains but also by what remains unformed.
Both Eagleman and Barrett argue that our upbringing influences:
- Our identities
- Our beliefs
- Our emotional expressions
- Our reactions to various situations
For instance, someone who has experienced the loss of a loved one may empathize deeply with another who has undergone similar grief, while someone without such experience might only feel a superficial sympathy.
A Case Study in Early Adversity
Eagleman highlights the plight of Romanian orphans to underscore the significance of early life experiences. During the political turmoil of the 1980s and 1990s, many children were placed in neglectful orphanages, leading to severe emotional and cognitive repercussions. The lack of nurturing and cognitive engagement stunted their emotional and social development.
This case powerfully illustrates the brain's plasticity—the ability to adapt in response to experiences—and underscores the necessity of a supportive environment during early childhood for healthy brain development.
Summary
- The brain's wiring is adaptable, shaped by both genetics and life experiences.
- Humans exhibit exceptional adaptability compared to many animals due to our ability to form new neural connections.
- Emotion theories encompass both the classical view of universal emotions and the constructivist perspective, which emphasizes environmental influences.
- Experiences in childhood and adolescence significantly mold personality and emotional expression.
- Neuroplasticity allows for ongoing change and learning throughout adulthood, challenging the idea of fixed identities.
- It is essential to be mindful of one's environment and relationships, as they all contribute to shaping an individual's identity.

Chapter 2: The Power of Storytelling
In this chapter, we will explore how storytelling influences our understanding of the world and ourselves.
The first video, "Your Brain on Story," discusses the profound impact that narratives have on our brains, illuminating how stories can evoke emotions and foster connections.
Chapter 3: Leadership and Emotional Intelligence
The next chapter will delve into the significance of storytelling in leadership, drawing insights from Karen Eber's TED talk.
In "How your brain responds to stories -- and why they're crucial for leaders," Eber explains how effective storytelling can enhance leadership and emotional intelligence.
