Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 5Not checkedScientists who worked out how to control brain cells with light won this year's Nobel Prize in physiology or medicine for research into light-gated ion channels and optogenetics.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 2 of 5Not checkedHegemann and Nagel were studying how Chlamydomonas senses light when they discovered that the alga uses a protein called channelrhodopsin for light detection.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 3 of 5Not checkedWhen light hits retinaldehyde in channelrhodopsin, the protein changes shape and opens a membrane passage that lets positively charged particles enter the algal cell.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 4 of 5Not checkedResearchers realized that putting channelrhodopsin into nerve cells could allow those cells to be switched on simply by shining light on them, and that is what Deisseroth, Hegemann and Nagel later did.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 5 of 5Not checkedOptogenetics has become a powerful research tool for switching specific groups of nerve cells on and off to see what happens, and it may also have future therapeutic uses.View evidenceHide evidence
Not checked
NewsLink could not identify one source study, so this claim was not compared against a paper.
Method layer
No single source study was found.
NewsLink still surfaces nearby research so you can inspect the field instead of a single paper.
