A flexible high-precision photoacoustic retinal prosthesis

This paper presents a photoacoustic retinal prosthesis that stimulates retinal cells with high precision and safety, showing neural modulation in rat models.

Ectopic expression of two cone opsins in mouse RGCs results in opposite responses to light stimulation, likely due to differential G protein activation

This study shows that expressing short-wavelength cone opsin in RGCs causes hyperpolarization, opposite to mid-wavelength opsin's depolarization, due to different G-protein activation.

Encoding surprise by retinal ganglion cells

This study investigates whether retinal ganglion cells encode surprise by analyzing their responses to stochastic flash sequences and finding that their responses align with a normative model of surprise encoding.

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.

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.

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.
