DOMINANT ANGLE
Mexico City retains the 2026 Nobel Prize for the "light switch" that controls neurons and explains the formation of memories, emotions, and brain disorders.
Dominant angle identified — does not reflect unanimity of this country’s media
KEY POINTS
- 01
The 2026 prize is awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for light-activated ion channels and optogenetics, with 12 million Swedish crowns shared equally (Vanguardia MX).
- 02
According to El Financiero, the method has shown how neural circuits control memories, pain, social behaviors, thirst, feeding, attention, and circadian rhythms.

Per Svenningsson, Nobel committee president, states that optogenetics allows for brain mapping "like we could only dream of" (El Financiero).
ANALYSIS
Mexico, October 6, 2026. Mexican media is covering the awarding of the Nobel Prize in Physiology or Medicine to American Karl Deisseroth and Germans Peter Hegemann and Georg Nagel on Monday, October 5, from the angle of how the technique is changing the understanding of the brain.
El Financiero reports on a jury that distinguished three researchers "for having opened a new era in neuroscience". The economic daily highlights the explanation of memories: optogenetics shows how nerve cells form memories, feelings, and behaviors. It lists the functions illuminated by the method: the sensation of pain, social behaviors, thirst, food, attention, circadian rhythms, and even fever triggered by the immune system.
Vanguardia MX uses the metaphor of a switch in its title. The newspaper describes a technique that activates or deactivates precise groups of neurons through light stimuli, which has allowed for more precise observation of the role of circuits in memories, emotions, movements, and states of wakefulness. It recalls the award of 12 million Swedish crowns, shared equally among the three laureates.
Both titles quote Per Svenningsson, president of the Nobel Committee: optogenetics offers "possibilities to map the brain like we could only dream of". El Financiero adds the words of medical genetics professor Anna Wedell on a "giant step": we had anatomical maps, we can now produce functional maps and understand how different cells communicate.
On the medical front, El Financiero cites treatments currently being developed to restore vision in people with altered vision, and a better understanding of depression, anxiety, schizophrenia, Parkinson's, and Alzheimer's. The scientific story begins with the single-celled alga Chlamydomonas, studied by Hegemann in the 1990s for its rapid reaction to light, according to Vanguardia.
The articles essentially reproduce the press release from the Nobel Assembly of the Karolinska Institute. They do not mention any connection to Mexican research or debate on the clinical limitations or funding of these works.
