DOMINANT ANGLE
Buenos Aires sees this Nobel as a medical promise for the brain: the Argentine press explains optogenetics, a neuron switch, and its potential avenues against Parkinson's, epilepsy, and depression.

KEY POINTS
- 01
The 2026 Nobel Prize in Medicine is awarded to Karl Deisseroth (Stanford), Peter Hegemann, and Georg Nagel for light-activated ion channels and optogenetics (Perfil, Ámbito).
- 02
Deisseroth introduced the protein gene into rat neurons, published in 2005, and then got the switch working in the brains of living mice two years later (Ámbito).
- 03
Deisseroth explains to AFP that the brain has billions of cells with distinct functions and that light allows for control of certain cells without affecting others (Clarín).
ANALYSIS
Buenos Aires, October 6, 2026. Argentine media is dedicating the Nobel Prize in Medicine, announced on Monday, October 5, to an explanation of optogenetics and what it changes for the understanding of the brain. Clarín, Perfil, and Ámbito quote American Karl Deisseroth, from Stanford, and Germans Peter Hegemann and Georg Nagel, distinguished for "light-activated ion channels and optogenetics".
Perfil tells the story of the origin of the prize with a simple question: how does a single-celled alga detect light to swim towards it? The daily newspaper emphasizes that the technique makes it possible to prove causality, i.e., to show that a specific group of neurons produces a given response, whereas we only knew which regions were activated. It quotes the formula that optogenetics makes it possible to map the brain "in a way we could only dream of".
Ámbito details the chronology: Hegemann and Nagel discover channelrhodopsin in Chlamydomonas, which opens to blue light; Deisseroth introduces the gene into rat neurons, publishes in 2005, and then gets the switch to work in the brains of living mice two years later. The title evokes possible advances against Parkinson's, epilepsy, and depression, and the text specifies Deisseroth's age, 54, born in Boston.
Clarín publishes two texts. The first is a general-audience explanatory piece: researchers introduce light-sensitive proteins into certain cells, then activate or deactivate these neurons with a light beam, which has made it possible to study movement, memories, and emotions. The second reprints an interview with Deisseroth by the AFP. The laureate explains that the brain has billions of cells with different functions and that "a way to distinguish them" was needed. He also emphasizes that in psychiatry, unlike cardiology, there was a lack of a good model of what really differs.
The coverage therefore remains centered on the science and its expected clinical applications, without local debate on research funding or the state of Argentine science. The laureates are presented through their background and university, and the Nobel Committee is quoted to describe the opening of "a new era in neuroscience".
