Julia Rodríguez Teba, neuroscience expert: “Mental noise is one of the major invisible causes of stress”

Julia Rodríguez Teba is an expert in neuroscience applied to emotional management and human performance, with training in neuropsychology, epigenetics, integrative medicine and advanced mental control techniques. She has developed the Brain Star Training method, a system designed to reduce internal noise and enhance cognitive regulation, neuroemotional stability and overall brain performance.

As a mental mentor and brain trainer, she works with executives, professionals and teams undergoing transformation. Her goal is to make applied neuroscience accessible to anyone who wants to better understand and regulate their mind, regardless of their field or prior experience. With that in mind, Rodríguez Teba has published Sin ruido – a book that explains how to silence your mind “to think and choose better.”

“Mental noise is one of the great invisible causes of stress, paralysis and difficulty making decisions, especially in a context of cognitive and emotional overload in which we live permanently accelerated,” she explains. “From applied neuroscience, neuropsychology and brain training, I guide mental training processes that help people understand what is happening in the brain, regulate its functioning and recover a more stable, present and conscious way of thinking, feeling and deciding.”

Your mind can be your greatest ally – or your worst enemy

The neuroscientist acknowledges that mental noise takes a toll: thoughts that spiral, emotions that drag us along and inherited patterns that distort our perception. “That constant hum exhausts us, confuses us and distances us from what we truly want. But the brain is not a fixed organ – it is malleable, capable of reorganizing itself and profoundly trainable.”

In Sin ruido, Rodríguez Teba guides readers through a process of self-knowledge grounded in neuroscience, psychology and clinical observation. Through a clear and accessible lens, you discover how your thoughts are formed, how they shape your emotions and how your body translates those internal states. You come to understand what is happening in your mind – and what you can begin to change today.

Through breathing exercises, guided visualizations, mindful attention practices and real-life case studies, readers learn to train their brains to quiet what is unnecessary, strengthen what matters and sustain a mind with greater calm, focus and direction. Based on the Brain Star Training method, the book offers a structured path designed to create a more ordered, stable and connected inner space.

“One of the most important keys to understanding your mind is recognizing that not all your thoughts come from the present. And this is where the difference between adaptive and conditioned thinking arises. Adaptive thinking is connected to your current reality. Conditioned thinking, on the other hand, does not respond – it repeats. It comes from the past. From mandates, expectations, invisible loyalties. It is that automatic thought that activates without asking whether it still makes sense. And often, it no longer does. The difference between one and the other can change your entire day and your whole way of living,” she concludes.
