UgandaNobel Prize awarded for brain technique
The 2026 Nobel Prize in physiology or medicine has been awarded to three scientists for their work developing a technique to decode the inner workings of the brain. The technique, known as optogenetics, helps scientists learn more about the human mind and has potential applications in clinical medicine.

The Nobel Committee announced the award at the Karolinska Institute in Sweden. The winners are Karl Deisseroth, a US psychiatrist and neurologist, and his German colleagues Peter Hegemann and Georg Nagel.
The trio was praised for laying the foundation of a new era in neuroscience by revealing how to switch on and off neural circuits behind specific memories, feelings, and behaviours. This has helped scientists better understand how the human mind works.
Optogenetics is a way to illuminate brain pathways using a special protein borrowed from algae. The protein, known as channelrhodopsin, was discovered by Hegemann and Nagel in the early 2000s. Deisseroth later worked out how to use this light-controlled protein to switch on nerve cells in the brains of mice.
Researchers have since been able to study nerve cells and pathways in animals to see and discover more about what they do. The Nobel Committee said this has provided important insights into how the nervous system interacts with various cells in other areas of the body.
The winners will share the £900,000 prize money. Per Svenningsson, chair of the Nobel Committee for Physiology or Medicine, said optogenetics provides opportunities for mapping the brain in a way that was previously impossible.
Optogenetics has potential applications in clinical medicine, including restoring sight in people with visual impairment. The Nobel Assembly said every day brings new discoveries, helping to solve one of humanity's great mysteries: how the brain works.
The winners said it was an honour to share the accolade with friends. They described the award as absolutely wonderful.

Three perspectives
Neutral
The award recognizes the significant contribution of the trio to the field of neuroscience. Their work has the potential to lead to new treatments for various neurological and psychiatric disorders. The development of optogenetics is a major breakthrough in understanding the human brain.
Positive
The award is a well-deserved recognition of the trio's groundbreaking work. Their discovery has opened up new avenues for research and has the potential to improve the lives of millions of people. The development of optogenetics is a testament to human ingenuity and the power of scientific collaboration.
Negative
Some critics may argue that the award is too focused on basic research and does not adequately recognize the contributions of other scientists. Others may be concerned about the potential risks and ethical implications of using optogenetics in clinical medicine. The development of optogenetics also raises questions about the long-term consequences of manipulating the human brain.
