Three-dimensional scanless holographic optogenetics with temporal focusing (3D-SHOT). [PDF]

open access: yes, 2017
Optical methods capable of manipulating neural activity with cellular resolution and millisecond precision in three dimensions will accelerate the pace of neuroscience research. Existing approaches for targeting individual neurons, however, fall short of

X-Optogenetics and U-Optogenetics: Feasibility and Possibilities

open access: yesPhotonics, 2015
Optogenetics is an established technique that uses visible light to modulate membrane voltage in neural cells. Although optogenetics allows researchers to study parts of the brain like never before, it is limited because it is invasive, and visible light

Step Sequence is a Critical Gait Parameter of Unilateral 6-OHDA Parkinson's Rat Models

open access: yesCell Transplantation, 2017
Parkinson's disease is a progressive neurological disorder, marked by the loss of dopaminergic neurons in the nigrostriatal pathway that leads to abnormal gait, rigidity, slowness of movement, and tremor.

Optical excitation and detection of neuronal activity [PDF]

open access: yes, 2017
Optogenetics has emerged as an exciting tool for manipulating neural activity, which in turn, can modulate behavior in live organisms. However, detecting the response to the optical stimulation requires electrophysiology with physical contact or ...

The Roles of Optogenetics and Technology in Neurobiology: A Review

open access: yesFrontiers in Aging Neuroscience, 2022
Optogenetic is a technique that combines optics and genetics to control specific neurons. This technique usually uses adenoviruses that encode photosensitive protein. The adenovirus may concentrate in a specific neural region.

Rods progressively escape saturation to drive visual responses in daylight conditions

open access: yesNature Communications, 2017
Rod photoreceptors are thought to be saturated under bright light. Here, the authors describe the physiological parameters that mediate response saturation of rod photoreceptors in mouse retina, and show that rods can drive visual responses in photopic ...

AAV1 is the optimal viral vector for optogenetic experiments in pigeons (Columba livia)

open access: yesCommunications Biology, 2021
Rook et al. establish a viral gene transfer system to perform optogenetics in pigeons. They deliver ChR2 via AAV1 into the visual entopallium and show its behavioral relevance for contrast perception, verifying the applicability of optogenetics in an ...

Separate roles of PKA and EPAC in renal function unraveled by the optogenetic control of cAMP levels in vivo [PDF]

open access: yes, 2013
Cyclic AMP (cAMP) is a ubiquitous second messenger that regulates a variety of essential processes in diverse cell types, functioning via cAMP-dependent effectors such as protein kinase A (PKA) and/or exchange proteins directly activated by cAMP (EPAC ...

Fighting against fast speckle decorrelation for light focusing inside live tissue by photon frequency shifting [PDF]

open access: yes, 2020
Light focusing inside live tissue by digital optical phase conjugation (DOPC) has drawn increasing interest due to its potential biomedical applications in optogenetics, microsurgery, phototherapy, and deep-tissue imaging.

Prospects for optogenetic augmentation of brain function

open access: yesFrontiers in Systems Neuroscience, 2015
The ability to optically control neural activity opens up possibilities for the restoration of normal function following neurological disorders. The temporal precision, spatial resolution and neuronal specificity that optogenetics offers is unequalled by
