#optogenetics — Public Fediverse posts

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.

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.

#KnowledgeByte: #Optogenetics is a biological technique that combines genetics and optics to control the activity of individual, light-sensitive neurons or cells in living tissue with high temporal precision (milliseconds).

Adam Claridge-Chang and Shiqiang Gao analyse K+ channelrhodopsins:

"both the absolute K+ to Na+ permeability ratio and its stability over time determine the inhibition to activation transition, which limits their utility for silencing neural circuits."

And they found that a single aminoacid mutant, KCR1-C29D, "shows a relatively high and the most stable K+ to Na+ permeability ratio during illumination", better than heavily protein engineered versions.

It's interesting that uses of optogenetic therapies work well with goggles that translate RGB video input to "retinal codes" that are projected in the frequency range and amplitudes appropriate for the light sensitive rhodopsins. Fascinating.

Researchers used #optogenetics to stimulate epidermal cells in #drosophila larvae, triggering escape behaviours even without injury.

This shows that mechanosensory signals can drive nociceptive responses, linking touch detection to pain responses.

Hi folks! Here is my #introductionpost. I am a #neuroscientist & #psychiatrist based in NYC. I started a lab at Columbia in 2021 focused on how #stress disrupts the #brain #circuits that govern social, cognitive & reward seeking #behavior. We use #electrophysiology & #optogenetics in freely moving mice to study how dynamic #neural activity, eg, #oscillations yield insight into #susceptibility #resilience #anhedonia & new treatments. I also post about #cooking. #twitterMigration #NeuroMastodons
