Behavioral and neural mechanisms of latent inhibition

open access: yesLearning & Memory, 2022
Fear is an adaptive emotion that serves to protect an organism against potential dangers. It is often studied using classical conditioning paradigms where a conditioned stimulus is paired with an aversive unconditioned stimulus to induce a threat response.

Beyond pulsed inhibition: Alpha oscillations modulate attenuation and amplification of neural activity in the awake resting state

open access: yesCell Reports, 2023
Summary: Alpha oscillations are a distinctive feature of the awake resting state of the human brain. However, their functional role in resting-state neuronal dynamics remains poorly understood.

Highly efficient neural conversion of human ES and iPS cells by dual inhibition of SMAD signaling

open access: yesNature Biotechnology, 2009
Current neural induction protocols for human embryonic stem (hES) cells rely on embryoid body formation, stromal feeder co-culture or selective survival conditions.

Neural mechanisms underlying expectation-dependent inhibition of distracting information

open access: yesbioRxiv, 2020
Predictions based on learned statistical regularities in the visual world have been shown to facilitate attention and goal-directed behavior by sharpening the sensory representation of goal-relevant stimuli in advance. Yet, how the brain learns to ignore

Stretching the limits of maximal voluntary eccentric force production in vivo

open access: yesJournal of Sport and Health Science, 2018
During eccentric contractions, muscular force production capacity is enhanced compared to isometric contractions. Although this is well accepted in terms of muscle mechanics, maximal voluntary eccentric contractions are associated with neural inhibition ...

Socioeconomic status and neural processing of a go/no-go task in preschoolers: an assessment of the P3b [PDF]

open access: yes, 2019
While it is well established that lower socioeconomic status (SES) is associated with poorer executive functioning (EF), how SES relates to the neural processing of EF in childhood remains largely unexplored.

Inhibitory control of correlated intrinsic variability in cortical networks

open access: yeseLife, 2016
Cortical networks exhibit intrinsic dynamics that drive coordinated, large-scale fluctuations across neuronal populations and create noise correlations that impact sensory coding.

Lateral inhibition: inherent recurrent processes in coherent optical propagation [PDF]

open access: yes, 1994
Processes that are analogous to the neural process of recurrent lateral inhibition can be found in optical systems that consist of a shift-invariant system and a Fabry-Perot cavity.

Engineering a Light-Regulated GABAA Receptor for Optical Control of Neural Inhibition

open access: yesACS Chemical Biology, 2014
Optogenetics has become an emerging technique for neuroscience investigations owing to the great spatiotemporal precision and the target selectivity it provides. Here we extend the optogenetic strategy to GABAA receptors (GABAARs), the major mediators of

Molecular mechanisms underlying resting-state brain functional correlates of behavioral inhibition

open access: yesNeuroImage, 2023
Previous literature has established the presence of sex differences in behavioral inhibition as well as its neural substrates and related disease risk.
