  "account": "The Nobel Prize in Physiology or Medicine 2026 has been awarded to Karl Deisseroth, Peter Hegemann, and Georg Nagel for their groundbreaking work in optogenetics. This revolutionary technology involves the use of light-gated ion channels to control and manipulate specific neuronal cell types within intact circuits in the brain. Deisseroth, who is a Professor at Stanford University, Hegemann, a Hertie Senior Research Chair at Humboldt University, and Nagel, a professor at the University of Würzburg, were recognized for their discoveries that have transformed neuroscience research.\n\nOptogenetics enables researchers to map the brain in unprecedented detail, a feat once thought impossible. The technology was first proposed by Francis Crick in the 1960s, who suggested that light could be used to selectively activate or inactivate specific types of neurons. The concept gained momentum in the 1970s with the discovery of algal protein channelrhodopsin, which can directly convert photon energy into transmembrane ion flux.\n\nThe first direct evidence of a light-gated ion channel was discovered by the Hegemann lab and named channelrhodopsin-1 (ChR1). Just a year later, a collaborative team led by Nagel demonstrated that a second protein, channelrhodopsin-2 (ChR2), functioned differently from ChR1, with a distinct blue-shifted activation spectrum and broad, non-selective cation channel properties. The Deisseroth lab took the lead in developing optogenetics further, successfully expressing ChR2 in neurons and triggering nerve signals using blue light.\n\nSince its inception, optogenetics has been used to investigate various biological questions in neuroscience, including the causal relationship between the activation of specific neurons and transitions from sleep to wakefulness, the search for memory engrams, and the understanding of dopaminergic neurons in the retina. The technology has also found clinical applications, such as restoring vision in mice with retinitis pigmentosa by expressing ChR2 in retinal ganglion cells.",
