DOMINANT ANGLE
Rome sees this Nobel as the consecration of a tool: optogenetics, the "switch" that allows for the activation and deactivation of specific neurons with light.

ANALYSIS
Rome, October 6, 2026. The Italian press opens the week of the Nobel Prizes with the announcement of the medicine award, announced on Monday, October 5: Karl Deisseroth, Peter Hegemann, and Georg Nagel are being rewarded "for their discoveries related to light-activated ion channels and optogenetics," according to the motivation of the Nobel Assembly of the Karolinska Institutet, as reported by ANSA.
The story prioritizes education. Panorama invites readers to imagine the brain "as a huge electrical network" where one can choose a specific switch, turn it on, turn it off, and immediately observe what changes. The magazine emphasizes the difference between observing that a particular area is activated during an emotion and knowing whether this activity is the cause, consequence, or simply a concurrent phenomenon: optogenetics, it writes, provides a tool to selectively modify the activity of specific neurons with great temporal precision. It sees this as a revolution that, over the past twenty years, has changed the way the brain is studied.
ANSA details the chain of discoveries. Hegemann and Nagel paved the way with the protein called channelrhodopsine, which makes cells sensitive to light when introduced. Deisseroth then transferred the gene into rat neurons and, by exposing them to blue light, triggered a nerve signal. The method is now used in laboratories around the world to understand how the brain organizes emotions and memories.
The agency also recalls the context of the predictions: among the most cited candidates by experts were GLP-1 type anti-obesity medications, orexin for sleep regulation, the non-invasive OCT technique for the retina, and receptors of the immune system. It specifies that the week continues with the physics award on the 6th and chemistry on the 7th.
La Repubblica, written by Elena Dusi, summarizes the laureates as "brain researchers" whose technique allows for the activation and deactivation of neurons in test subjects, and notes that these prizes are in their 125th edition. The coverage remains factual and focused on the technique, without an Italian angle or debate on research funding.
