Behavioural and neural markers of tactile sensory processing in infants at elevated likelihood of autism spectrum disorder and/or attention deficit hyperactivity disorder

Journal of Neurodevelopmental Disorders, 2021
Backgrounds Atypicalities in tactile processing are reported in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) but it remains unknown if they precede and associate with the traits of these disorders emerging in ...

Stimulus-specific plasticity in human visual gamma-band activity and functional connectivity

eLife, 2021
Under natural conditions, the visual system often sees a given input repeatedly. This provides an opportunity to optimize processing of the repeated stimuli. Stimulus repetition has been shown to strongly modulate neuronal-gamma band synchronization, yet

On the relationship between persistent delay activity, repetition enhancement and priming

Frontiers in Psychology, 2015
Human efficiency in processing incoming stimuli (in terms of speed and/or accuracy) is typically enhanced by previous exposure to the same, or closely related stimuli - a phenomenon referred to as priming.

Toward a Broadband Astro-comb: Effects of Nonlinear Spectral Broadening in Optical Fibers [PDF]

, 2010
We propose and analyze a new approach to generate a broadband astro-comb by spectral broadening of a narrowband astro-comb inside a highly nonlinear optical fiber.

Human scalp electroencephalography reveals that repetition suppression varies with expectation

Frontiers in Human Neuroscience, 2011
Repetitions of a sensory event elicit lower levels of brain activity than its initial presentation (‘repetition suppression’). According to one view, repetition suppression depends on the biophysics of neuronal discharge, and is thus an automatic ...

Hemispheric Asymmetries in Repetition Enhancement and Suppression Effects in the Newborn Brain. [PDF]

PLoS ONE, 2015
The repeated presentation of stimuli typically attenuates neural responses (repetition suppression) or, less commonly, increases them (repetition enhancement) when stimuli are highly complex, degraded or presented under noisy conditions.

Investigation of noise suppression, pulse intensity and chirp of an actively mode-locked semiconductor fiber ring laser [PDF]

, 2007
An actively mode-locked fiber ring laser that utilizes an EDFA and semiconductor optical amplifier (SOA) is presented. The SOA enhances noise suppression. Active mode-locking was demonstrated at repetition rates up to 20 GHz.

A habituation account of change detection in same/different judgments [PDF]

, 2011
We investigated the basis of change detection in a short-term priming task. In two experiments, participants were asked to indicate whether or not a target word was the same as a previously presented cue.

Corticofugal regulation of predictive coding

eLife, 2022
Sensory systems must account for both contextual factors and prior experience to adaptively engage with the dynamic external environment. In the central auditory system, neurons modulate their responses to sounds based on statistical context.

Context-dependent minimisation of prediction errors involves temporal-frontal activation

NeuroImage, 2020
According to the predictive coding model of perception, the brain constantly generates predictions of the upcoming sensory inputs. Perception is realised through a hierarchical generative model which aims at minimising the discrepancy between predictions
