CONICET researchers achieved a high-impact scientific breakthrough: they demonstrated that synchronized stimulation with intermittent light and sound can promote the generation of new neurons in aging brains, strengthening the hippocampus and opening perspectives for the treatment of Alzheimer's and other neurodegenerative diseases.

🧠 The scientific finding

• Participating institutions: CONICET and Leloir Institute Foundation.
• Methodology: application of intermittent visual and auditory stimuli, synchronized in gamma frequency.
• Results: In animal models, the integration of new neurons into brain circuits was observed, especially in the hippocampus, a key region for memory and learning.

🔑 Relevance of the discovery

• Neurogenesis in aged brains: it was proven that even at advanced ages it is possible to regenerate neurons.
• Strengthening of the hippocampus: the technique reinforces the neural circuits affected in Alzheimer's.
• Non-invasive alternative: synchronised audiovisual stimulation is emerging as an accessible and safe tool.
• Potential impact: It  could become a complementary approach to slow cognitive decline.

📊 Medical and social implications

⚠️ Challenges and next steps

• Validation in humans: so far the results are preclinical, in mice.
• Scalability: it is necessary to adapt the technique to real clinical contexts.
• Regulation and ethics: any therapeutic application must pass safety and efficacy tests.

🎙️ Conclusion

The CONICET study marks a milestone in Argentine neuroscience. With an innovative approach, the researchers showed that the combination of light and sound can reactivate the brain's ability to generate neurons, even in stages of aging. This finding opens a path of hope in the face of Alzheimer's, a disease that affects millions of people in the world.
