🧠🔦 It’s finally there: #NeuropixelsOpto which integrates high-density #electrophysiology and #optogenetics on the same probe.

The just presented prototype combines 960 recording sites w 14 blue & 14 red light emitters on a 70 µm-wide shank, enabling spatially addressable #optogenetic activation, silencing and #optotagging during large-scale recordings.

Using light, animal behaviors cease to be internal choices and become external toggles. Scientists can flick a switch to turn fundamental drives up or down, including aggression, nurturing, hunger, thirst, and sleep. This mechanical ease implies our own complex actions might be far more programmable than we care to acknowledge.

Section two, "Flipping the behavioral switch," explores how internal choices can become biological toggles. At Stanford, Karl Deisseroth industrialized mind control via optogenetics. Light-activated genes from algae are inserted into animal neurons, allowing researchers to control brains using fiber-optic pulses of light.

Visual perception is the result of orderly, stepwise computations in the mammalian brain, where specific cortical neurons construct complex visual information from broadly tuned neural inputs. This step-by-step processing allows the brain to selectively respond to distinct visual features, such as edges, contrast, and object orientation.

Proof for theory of visual perception

A scientific dispute spanning six decades about fundamental mechanisms of visual perception in mammals has now been settled.

The tegmentum region in the zebrafish midbrain integrates light signals from both the eyes and the pineal organ (the "third eye") to coordinate spatial orientation. This neural integration allows the fish to adjust its up-and-down swimming behavior based on the specific wavelengths of ambient environmental light.

Researchers Develop Light-Controlled Protein Evolution for Dynamic Cellular Functions

Scientists at the Ecole Polytechnique Fédérale de Lausanne have developed a novel method called ‘optovolution’ that uses light to guide the evolution of proteins with dynamic behaviors.
