Optogenetic Activation of a Lateral Hypothalamic-Ventral Tegmental Drive-Reward Pathway. [PDF]

PLoS ONE, 2016
Electrical stimulation of the lateral hypothalamus can motivate feeding or can serve as a reward in its own right. It remains unclear whether the same or independent but anatomically overlapping circuitries mediate the two effects. Electrical stimulation

Functional MRI Readouts From BOLD and Diffusion Measurements Differentially Respond to Optogenetic Activation and Tissue Heating

Frontiers in Neuroscience, 2019
Functional blood-oxygenation-level-dependent (BOLD) MRI provides a brain-wide readout that depends on the hemodynamic response to neuronal activity. Diffusion fMRI has been proposed as an alternative to BOLD fMRI and has been postulated to directly rely ...

Alternation of Neuronal Feature Selectivity Induced by Paired Optogenetic-Mechanical Stimulation in the Barrel Cortex

Frontiers in Neural Circuits, 2021
Paired stimulation has been applied to modulate neuronal functions in the primary somatosensory cortex but its utility in the alternation of tuning function, such as direction tuning for whisker stimuli, remains unclear.

Near physiological spectral selectivity of cochlear optogenetics

Nature Communications, 2019
Cochlear implant spectral resolution is limited by current spread from each stimulation electrode. Here the authors compare optogenetic, electric and acoustic stimulation in gerbils and demonstrate improved spectral resolution of optogenetic over ...

Caudal optogenetic spinal stimulation promotes better therapeutic outcomes than rostral optogenetic stimulation following a cervical spinal cord injury

Frontiers in Neuroscience
PurposeSpinal stimulation, including optogenetic stimulation, is a promising therapeutic approach for promoting functional recovery after spinal cord injury (SCI).

A shape-memory and spiral light-emitting device for precise multisite stimulation of nerve bundles

Nature Communications, 2019
Optogenetic stimulation of damaged peripheral nerves has advantages over electrical stimulation but it’s limited to single-site stimulation. Here the authors develop a spiral-shaped LED implant for precise optogenetic stimulation of peripheral nerve ...

Activation of CamKIIα expressing neurons on ventrolateral periaqueductal gray improves behavioral hypersensitivity and thalamic discharge in a trigeminal neuralgia rat model

The Journal of Headache and Pain, 2021
Background Preceding studies have reported the association of chronic neuropathic orofacial pain with altered ongoing function in the ventrolateral periaqueductal gray (vlPAG). However, its role in trigeminal neuralgia (TN) lacks attention.

Bimodal activation of different neuron classes with the spectrally red-shifted channelrhodopsin chimera C1V1 in Caenorhabditis elegans [PDF]

, 2012
The C. elegans nervous system is particularly well suited for optogenetic analyses of circuit function: Essentially all connections have been mapped, and light can be directed at the neuron of interest in the freely moving, transparent animals, while ...
