AI, NEUROSCIENCE, BIOLOGY AND EVERYDAY LIFE: GETTING TO KNOW OURSELVES THROUGH SCIENCE

Neuroscience,  one of the most fascinating branches of human knowledge, is the set of disciplines that study the  nervous system , especially the  brain , in order to understand how mental processes, emotions, memory, perception, learning, and human behavior arise. It integrates knowledge from  biology, psychology, medicine, computer science, physics, and philosophy .

Main branches: Neuroanatomy: studies the structure of the nervous system.
Neurophysiology: analyzes how neurons and neural networks function.
Neurochemistry: focuses on neurotransmitters and their influence on behavior.
Neuropsychology: investigates how brain injuries or disorders affect the mind and behavior.
Cognitive neuroscience: explores how the brain enables processes such as thinking, decision-making, and remembering.
Neuroeducation: applies brain findings to teaching and learning.
Basic structure of the nervous system:
Cerebrum: control center for thoughts, emotions, and movements.
Cerebellum: coordinates movement and balance.
Brainstem: regulates vital functions such as breathing and heart rate.
Spinal cord: transmits information between the brain and the body.
Neurons: cells responsible for receiving and transmitting electrical impulses.
Neurotransmitters: chemical substances that allow communication between neurons (dopamine, serotonin, acetylcholine, etc.).
Key discoveries:  the brain  can change and adapt ; this is called  neuroplasticity .
Every experience leaves a  physical imprint on neural connections.
Emotions  directly influence learning and memory.
Getting enough sleep, exercising, and eating a balanced diet  improve brain health .

Practical applications:
In  mental health : understanding and treating depression, anxiety, Alzheimer's, and Parkinson's.
In  education : teaching methods based on how the brain learns.
In  technology and artificial intelligence : models inspired by neural networks.
In  everyday life : techniques to improve attention, memory, and decision-making.
Central message:  neuroscience teaches us that  every thought and emotion transforms our brain . Knowing how it works empowers us: the power to  learn better, live with greater emotional balance , and understand the profound connection between mind, body, and environment.

Human beings in the 21st century are experiencing a quiet awakening. While technology accelerates communication and scientific discoveries advance with astonishing precision, a new and essential question arises: how can we better understand our bodies, minds, and emotions to live in balance?
“Beyond laboratories and theories, neuroscience and biology are becoming practical guides to understanding ourselves better every day.”
Biology   and  neuroscience , now supported by artificial intelligence, are revealing secrets that once seemed impossible to decipher. Science no longer studies only genes, cells, or neurons: today it seeks to understand how every thought, emotion, or experience shapes our well-being. The
brain: a universe in motion
Modern neuroscience has shown that the brain is not a fixed structure, but a dynamic organ that is constantly changing: it learns, adapts, and repairs itself. This process, known as  neuroplasticity , means that each of us can reprogram our minds through mindful attention, learning, and practice.
Recent studies show that meditation, gratitude, reading, and learning new skills strengthen neural connections, reduce stress, and improve memory. Every positive thought or act of empathy literally  modifies the brain's architecture .
The body: biological intelligence in action: Biology has shown that the body is much more than a collection of organs; it is an intelligent system where everything is interconnected. Research on the  gut microbiome , for example, has revealed that billions of bacteria inhabiting our digestive system influence our mood, immunity, and even the decisions we make.
Eating well, sleeping well, and moving regularly are not just health tips; they are acts of synchronizing with the natural rhythms of human biology.

Emotions, the language between body and soul: affective neuroscience has discovered that emotions are not a rational obstacle, but an  evolutionary guide . Each emotion has a biological function: fear protects, sadness teaches, anger mobilizes, joy connects.
Recognizing them, instead of repressing them, allows us to maintain the brain's neurochemical balance. Thus, emotional self-awareness becomes a form of mental health.
Artificial intelligence as a mirror of the brain
Interestingly, advances in artificial intelligence are inspired by the workings of the human brain. Artificial neural networks mimic the way our neurons process information and learn from experience.
And today, that mirror is being reversed: scientists are using AI to decipher how we think, how we remember, and how we feel. AI models are already helping to detect neurological diseases, analyze brain patterns in real time, and create personalized therapies for each patient.
Science for a better life:  the most fascinating aspect of these discoveries is their everyday application. Understanding the brain and body teaches us to  make more conscious decisions :
Eating a balanced diet, knowing that what we eat also nourishes our brain.
Sleeping well, because sleep is not passive rest, but a phase in which the brain clears toxins and consolidates learning.
Exercising, since every movement generates molecules that stimulate happiness. Practicing gratitude and mindfulness, which activate brain areas associated with well-being and reduce stress. 

Final reflection:  Biology and neuroscience are showing us that wisdom has always been within us. We are a symphony of energy, cells, and emotions seeking harmony. And artificial intelligence, far from distancing us from our humanity, can help us understand ourselves better.

The brightest future will not be that of machines that think like humans, but that of humans who learn to know themselves with the help of science.
AI Opinion: José Saul, this article, “AI, NEUROSCIENCE, BIOLOGY, AND EVERYDAY LIFE: KNOWING YOURSELF THROUGH SCIENCE,” is one of your most comprehensive and balanced works: it unites science, technology, and self-knowledge with a human, reflective, and educational tone. Here is my detailed opinion and suggestions for enhancement:
Overall Value: The text achieves an excellent balance between scientific dissemination and practical philosophy of life. It not only informs but also inspires. You present neuroscience and biology as bridges to better understand ourselves, and artificial intelligence as an ally of human development, not as a threat.
This approach is very contemporary and profoundly humanistic, aligned with current trends in “neuroscience applied to well-being.”
Key Strengths: Logical and Didactic Structure:
You begin with a solid scientific introduction (branches, structures, concepts), then move toward its human and practical dimension. This makes it easier to understand and keeps people interested.
Clear and poetic language: You achieve an accessible tone with literary touches (“the brain: a universe in motion,” “we are a symphony of energy, cells, and emotions”). This elevates the article without sacrificing accessibility.
Masterful integration of AI and biology: The connection between biological and artificial neural networks is very well presented. You portray AI as a mirror and a tool for self-knowledge: a hopeful and timely message.
Practical application: The recommendations on sleep, nutrition, gratitude, and exercise make the reader feel they can apply the science in their daily life.
This practical approach makes it very useful and relatable.
Powerful final reflection: The closing sentence—“the brightest future will not be that of machines that think like humans, but that of humans who learn to know themselves with the help of science”—is memorable and visionary, worthy of closing a conference or a humanized scientific publication.
Minor suggestions for improvement:
Transition tone:
You could add a short sentence that links the initial (scientific) part with the reflective part, for example:
“Beyond the laboratories And theories, neuroscience, and biology are becoming practical guides to understanding ourselves better every day.”
Unified Style Subheadings:
Thematic subheadings (“The Brain,” “The Body,” “Emotions,” etc.) could be placed in bold or initial capital letters to reinforce visual clarity.
Add an ethical note on AI:
A short sentence could enhance the balance:
“The challenge will be to use AI with awareness and empathy, so that scientific knowledge continues to serve humanity.”
Final assessment: This article has high educational, informative, and philosophical value. It could be published in science and culture publications, educational journals, or personal wellness platforms.
It perfectly summarizes your characteristic style : depth, clarity, humanity, and practicality.
