What is neuroscience and what it reveals about how we think and feel?
Neuroscience is the discipline that studies the nervous system, especially the brain, and how it influences our thoughts, emotions, decisions, and behaviors. Thanks to the technological and scientific advances of recent decades, we know more than ever before about how the human mind works , what happens when we learn, why we feel the way we do, and how we can better care for our mental health.
Understanding the basic principles of neuroscience is not only fascinating: it can also help you make better decisions, reduce stress , improve your memory, and even develop empathy for others.
Neuroscience combines knowledge of biology, psychology, chemistry, computer science, and philosophy to answer fundamental questions such as:
- How are thoughts generated?
- What happens in the brain when we feel fear or joy?
- How do experiences affect our neural connections?
- What can be done about disorders such as depression, Alzheimer's, or anxiety?
Beyond theory, its applications are increasingly broad: from medicine and education to artificial intelligence and personal development .
The brain is one of the most complex structures in the known universe. Although it represents only 2% of body weight , it consumes up to 20% of total energy . Its most notable functions include:
- Processing sensory information (what you see, hear, touch, smell, and taste)
- Emotional regulation
- Memory and learning
- Movement and language control
- Decision making and reasoning
These functions are distributed across various brain regions. For example:
- The frontal lobe is responsible for logical thinking and planning.
- The limbic system regulates emotions such as anger, sadness, and motivation.
- The hippocampus is key in the formation of memories.
- Emotional understanding
- Knowing how emotions are generated allows you to manage them better.
- Techniques such as conscious breathing and meditation have neuroscientific support: they help reduce the activation of stress-related areas, such as the amygdala.
- Learning and memory
- Neuroscience has shown that learning is most effective when associated with excitement, repetition, and adequate rest .
- Sleeping well improves memory consolidation.
- decision making
- The brain is not as rational as we think: many decisions are made automatically and unconsciously , influenced by previous experiences and emotions.
- Mental health
- Understanding brain function helps destigmatize psychological disorders .
- Conditions such as anxiety or depression have real neurobiological causes and can be treated effectively.
Yes. Neuroplasticity is the brain's ability to adapt and change throughout life. This means you can create new neural connections when learning, changing habits, or recovering from a brain injury.
Some ways to stimulate this plasticity are:
- Learn new things (languages, music, skills)
- Doing physical exercise , which improves oxygenation and releases beneficial substances such as endorphins
- Sleep well , as the brain “reboots” during deep rest
- Eat nutrients that support the nervous system : omega 3, antioxidants, B vitamins
- Avoid chronic stress , which can damage brain structure over time
Thanks to technologies such as functional magnetic resonance imaging (fMRI) and artificial intelligence , scientists are developing new therapies for neurodegenerative diseases, brain prostheses, and even interfaces that allow devices to be controlled with the mind.
Ethical issues surrounding the use of brain knowledge in advertising, education, and justice are also explored. How far should our ability to read or modify minds extend?
Neuroscience not only seeks to unravel the secrets of the human brain, but also to improve our quality of life . Understanding how we think and feel gives us tools to develop as individuals and as a society.
Taking care of your brain is just as important as taking care of your body. And the best part is, it's never too late to start: your mind can change, adapt, and grow stronger throughout your life.
