Find out how neuroscience is changing our understanding of the brain, according to neuroscientist Diego Redolar

The human brain, a complex and interesting structure, not only regulates our vital functions, but also develops and adapts to environmental stimuli. Diego Redolar, director of the Cognitive Neurolaboratory at the Oberta University of Catalonia, explains how our experiences, habits and stress affect brain function. In this interview, he explores topics such as neural plasticity, learning, and the impact of technology on our cognitive abilities.

How does the brain adapt to change?

Brain plasticity initially associated with childhood continues to operate throughout life. This ability allows our brain to adapt to new circumstances, optimizing responses and ensuring our survival. According to Redolard, this flexibility played a key role in human evolution, allowing us to adapt to changing environments.

A prime example is the amygdala, which is responsible for processing danger signals. Under unfavorable conditions, this structure becomes more reactive, while under safe conditions it reduces its activity. However, this adaptability can also cause disorders such as anxiety, where we perceive non-existent threats.

How do routine and technology influence?

Redolar emphasizes that simple activities such as walking promote neurogenesis, especially in the hippocampus, which is important for memory. On the other hand, technology also affects the brain. For example, heavy mobile device use alters the motor representation of fingers in the cerebral cortex. Likewise, video games, although controversial, improve cognitive skills such as attention and spatial memory.

Learning and genes: how do they influence?

Although we can learn throughout our lives, ease decreases as we age due to the maturation of critical structures. For example, language learning as an adult is more complex, especially in aspects such as intonation.

In addition, Redolar notes that factors such as stress and cortisol can activate or inhibit brain genes. The effects of these substances depend on the context and perception of the individual, demonstrating that even the emotional environment plays a critical role in genetic regulation.

What can we do to improve our brain health?

To optimize brain function, Redolar recommends:

• Exercise: Daily walking stimulates the formation of neurons.
• Restful sleep: removes metabolic waste from the brain.
• Cognitive activity: reading and learning improve memory and plasticity.
• Social media: Emotional support reduces the impact of stress.

The combination of these factors helps maintain optimal brain health and prevent disorders such as depression.

Diego Redolar invites us to think about the impact of our daily activities on brain health. Understanding how our daily routine, environment and emotions affect the brain is key to improving our well-being.
