## Definition
Optogenetics is a neural manipulation method identified in the source article's light-controlled excitation or inhibition of genetically targeted neurons layer.
## Relationships
[[wiki/Optogenetics|Optogenetics]] is related to [[wiki/Optogenetics and Chemogenetics|Optogenetics and Chemogenetics]] as light-controlled excitation or inhibition of genetically targeted neurons.

- In [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]], **V.2 — Optogenetics, Chemogenetics, and Causal Manipulation** provides the narrative context for **Optogenetics**: Recording activity establishes correlation between neural patterns and behavior; causal manipulation establishes which patterns are functionally responsible for which behaviors.

- **INF-0029 — Analytic.** Optogenetics gives cell-type specificity but is bounded by the optical scattering length of tissue; magnetic and acoustic modalities give depth but coarser selectivity. Every serious non-surgical interface program is now attempting the same synthesis of the two, and whichever pairing lands first sets the modality standard for decades.
- **INF-0036 — Established.** Optogenetic vision restoration has already produced partial clinical results in humans, which means installing a light-responsive receptor in a human nervous system is a completed procedure rather than a proposal. Every write-side architecture inherits that precedent.

## Simple Reminders, Quotations, and Thoughts
> "Given that one in five Americans is now taking a mind-altering drug(s), the experiment continues and accelerates. Never mind fields like optogenetics, which alter and reconnect our brains, thoughts, memories, fears using light stimuli projected inside the brain. Eventual implants will radically change brain design, inputs, and outputs. Having a baseline, a good paleoneurological history of brain design, for ourselves and many other basic species, may teach us a lot about what our brains were, where they came from, but even more important, what they are becoming. I bet this is a challenge Tilly Edinger would have relished."

> "I foresee that the ability to measure and recreate brain activity at the level of specific neurons at will is about to transform us in ways that no other invention ever has. The invention of fire, of the wheel, of antibiotics or the Internet changed how we live our lives in profound ways. It made our lives safer, more comfortable, and more exciting. But they have not changed who we are. Being able to record and manipulate brain activity will change who we are. It will serve as an interface through which computers can become part of our brain, and through which our brains could directly interface with each other."

From [[wiki/Cyborg Soldier 2050|Cyborg Soldier 2050]]: The projected controller would guide a novice's movement through a proposed optogenetic sensor-and-stimulation system.
> "The optogenetic controller would, in effect, take control of the motions of a warfighter's limbs, thereby allowing a novice (i.e., the warfighter) to perform functions professionally."
