Optogenetic stimulation recruits cortical neurons in amorphology-dependent manner

This study shows that optogenetic stimulation activates cortical neurons in a morphology-dependent manner, with lateral spread influenced by neuronal layer and stimulation intensity.

In vivo optogenetic stimulation of the primate retina activates the visual cortex after long-term transduction

This study shows that optogenetic stimulation of the primate retina can activate the visual cortex for over 20 months, demonstrating long-term functionality and signal transmission.

Sonogenetic stimulation of the brain at a spatiotemporal resolution suitable for vision restoration

This paper demonstrates sonogenetic stimulation of the brain with high spatiotemporal resolution for visual restoration in rats and rodents.

Functional ultrasound imaging of the spreading activity following optogenetic stimulation of the rat visual cortex

This study uses optogenetics and functional ultrasound imaging to show that surface stimulation of the rat visual cortex activates a large volume of V1, including deep layers and areas beyond V1.

Optogenetic therapy: High spatiotemporal resolution and pattern recognition compatible with vision restoration in non-human primates

The paper evaluates an optogenetic construct for vision restoration in non-human primates, demonstrating high temporal resolution and visual acuity above legal blindness.

Modeling the Electro-chemical Properties of Microbial Opsin ChrimsonR for Application to Optogenetics-based Vision Restoration

The paper develops a model to predict ChrimsonR's electrochemical behavior under light stimulation, capturing its dynamics and adaptation mechanisms for optogenetics applications.
