New Capabilities

Deisseroth, Hegemann and Nagel win for turning light-sensitive algal proteins into switches for brain cells

2 days ago: Nobel Prize in Physiology or Medicine awarded

Overview

Updated 1 hour ago

The 2026 Nobel Prize in Physiology or Medicine went to three scientists who built a way to switch individual nerve cells on and off with light. Karl Deisseroth, Peter Hegemann and Georg Nagel share the 12 million Swedish kronor prize for optogenetics.

The prize caps a two-decade arc. Hegemann and Nagel found a light-sensitive protein in pond algae; Deisseroth turned it into a switch that works in living brains. The method has restored partial vision in a blind patient and is being tested for cochlear implants.

Why it matters

Optogenetics lets researchers prove which brain cells cause which behaviors, opening a path to treating psychiatric and neurological disorders.

  1. Nobel Prize in Physiology or Medicine awarded

    Latest Award

    Deisseroth, Hegemann and Nagel share the 12 million Swedish kronor prize for optogenetics.

  2. Memory engram activated in mice

    Breakthrough

    Deisseroth and Tonegawa reactivate fear memory nerve cells, causing mice to show fear without danger.

  3. Optogenetics works in living mice

    Breakthrough

    Deisseroth's group controls whisker movement by illuminating nerve cells in the motor cortex.

  4. Method named optogenetics

    Milestone

    The technique gets its name, combining 'optic' and 'genetics.'

  5. First light-controlled nerve cell switch

    Breakthrough

    Deisseroth introduces the channelrhodopsin gene into rat nerve cells and triggers signals with blue light.

  6. Channelrhodopsin discovered in algae

    Discovery

    Hegemann and Nagel identify a light-gated ion channel in the single-celled alga Chlamydomonas.

Scenarios

1

Optogenetics restores vision in more patients

Possible Resolves by End of 2028

Discussed by: Nobel Committee member Anna Wedell and the Nobel popular information

Clinical trials aim to restore vision in people blinded by retinitis pigmentosa, a disease that destroys the eye's rods and cones. A patient who received a channelrhodopsin-like protein regained some vision and could grasp objects. If trials expand and succeed, optogenetics becomes the first approved therapy built on this research.

2

Optogenetics moves into cochlear implants

Possible Resolves by End of 2028

Discussed by: Nobel popular information

Current cochlear implants stimulate the auditory nerve with electricity. Optogenetics could activate the nerve with greater precision. A first human trial would mark the method's second clinical application.

3

Optogenetics stays a research tool

Likely Resolves by End of 2028

Discussed by: Nobel Committee member Anna Wedell

Most optogenetics work happens in animal models. Wedell said the method is still primarily a basic science tool. Clinical applications beyond vision restoration may take years, and the method's main impact remains in mapping brain circuits.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

October 2021

Nobel Prize for temperature and touch receptors (2021)

David Julius and Ardem Patapoutian won the Nobel Prize in Physiology or Medicine for discovering TRP channels and Piezo proteins, the molecular sensors that let the body detect heat, cold and touch.

Then

The prize recognized work on sensory transduction that began in the 1990s.

Now

The discoveries opened new targets for pain and touch disorder treatments.

Why this matters now

Like optogenetics, the work identified specific proteins that convert physical stimuli into nerve signals, showing how molecular discovery can illuminate whole sensory systems.

October 2004

Nobel Prize for olfactory receptors (2004)

Richard Axel and Linda Buck won the Nobel Prize in Physiology or Medicine for discovering the family of receptors that detect odors. Their work showed how a large receptor family encodes a vast range of smells.

Then

The prize recognized the first molecular understanding of smell.

Now

The receptor family became a model for studying how sensory information is encoded in the brain.

Why this matters now

Both prizes recognized molecular discoveries that explained how sensory systems translate external signals into neural activity.
