Divergent projections of the prelimbic cortex bidirectionally regulate active avoidance

open access: yeseLife, 2020
The prefrontal cortex (PFC) integrates incoming information to guide our actions. When motivation for food-seeking competes with avoidance of danger, the PFC likely plays a role in selecting the optimal choice. In platform-mediated active avoidance, rats

The role of higher-order thalamus during learning and correct performance in goal-directed behavior

open access: yeseLife, 2022
The thalamus is a gateway to the cortex. Cortical encoding of complex behavior can therefore only be understood by considering the thalamic processing of sensory and internally generated information.

A high-light sensitivity optical neural silencer: development, and application to optogenetic control of nonhuman primate cortex

open access: yesFrontiers in Systems Neuroscience, 2011
Technologies for silencing the electrical activity of genetically-targeted neurons in the brain are important for assessing the contribution of specific cell types and pathways towards behaviors and pathologies.

Specificity, Versatility, and Continual Development: The Power of Optogenetics for Epilepsy Research

open access: yesFrontiers in Cellular Neuroscience, 2018
Optogenetics is a powerful and rapidly expanding set of techniques that use genetically encoded light sensitive proteins such as opsins. Through the selective expression of these exogenous light-sensitive proteins, researchers gain the ability to ...

Off-Target Influences of Arch-Mediated Axon Terminal Inhibition on Network Activity and Behavior

open access: yesFrontiers in Neural Circuits, 2020
Archaerhodopsin (ArchT)-mediated photoinhibition of axon terminals is commonly used to test the involvement of specific long-range neural projections in behavior.

Activation of the rostral nucleus accumbens shell by optogenetics induces cataplexy-like behavior in orexin neuron-ablated mice

open access: yesScientific Reports, 2023
Cataplexy is one of the symptoms of type 1 narcolepsy, characterized by a sudden loss of muscle tone. It can be seen as a behavioral index of salience, predominantly positive emotion, since it is triggered by laughter in humans and palatable foods in ...

Transgenic Archaerhodopsin-3 Expression in Hypocretin/Orexin Neurons Engenders Cellular Dysfunction and Features of Type 2 Narcolepsy

open access: yesJournal of Neuroscience, 2019
Narcolepsy, characterized by excessive daytime sleepiness, is associated with dysfunction of the hypothalamic hypocretin/orexin (Hcrt) system, either due to extensive loss of Hcrt cells (Type 1, NT1) or hypothesized Hcrt signaling impairment (Type 2, NT2)

Cl-out is a novel cooperative optogenetic tool for extruding chloride from neurons

open access: yesNature Communications, 2016
Chloride regulation is important for setting GABAergic reversal potential, though tools to manipulate chloride levels are limited. Here, the authors combine Archaerhodopsin with a chloride channel opsin to generate an optogenetic chloride extrusion ...

Optical silencing of C. elegans cells with arch proton pump. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Optogenetic techniques using light-driven ion channels or ion pumps for controlling excitable cells have greatly facilitated the investigation of nervous systems in vivo. A model organism, C.
