Repetition enhancement and perceptual processing of visual word form

Frontiers in Human Neuroscience, 2012
The current study investigated the cerebral basis of word perceptual repetition priming with fMRI during a letter detection task that manipulated the familiarity of perceptual word form and the number of repetitions.

Predictability engenders more efficient neural responses [PDF]

, 2009
The neural response to a stimulus diminishes with repeated presentations, a phenomenon known as repetition suppression. We here use neuroimaging to demonstrate that repetition suppression appears to be a special case of "prediction suppression"-

An ultra-sensitive pulsed balanced homodyne detector: Application to time-domain quantum measurements

, 2001
A pulsed balanced homodyne detector has been developed for precise measurements of electric field quadratures of pulsed optical quantum states. A high level of common mode suppression (> 85 dB) and low electronic noise (730 electrons per pulse) provide a

Does fMRI repetition suppression reveal mirror neuron activity in the human brain? Insights from univariate and multivariate analysis

European Journal of Neuroscience, 2019
Mirror neurons (MN) have been proposed as the neural substrate for a wide range of clinical, social and cognitive phenomena. Over the last decade, a commonly used tool for investigating MN activity in the human brain has been functional magnetic ...

Stimulus repetition probability effects on repetition suppression are position invariant for faces

NeuroImage, 2012
It has been shown that the probability of face repetitions influences the magnitude of repetition-related response reductions (Summerfield et al., 2008), implying that perceptual expectations affect adaptation and repetition suppression processes in the human central nervous system. An unresolved question is whether probability effects are specific for

Phonological repetition-suppression in bilateral superior temporal sulci [PDF]

NeuroImage, 2010
Evidence has accumulated that posterior superior temporal sulcus (STS) is critically involved in phonological processing during speech perception, although there are conflicting accounts regarding the degree of lateralization. The current fMRI experiment aimed to identify phonological processing during speech perception through repetition-suppression ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Neural Basis for Priming of Pop-Out during Visual Search Revealed with fMRI [PDF]

, 2017
Maljkovic and Nakayama first showed that visual search efficiency can be influenced by priming effects. Even "pop-out” targets (defined by unique color) are judged quicker if they appear at the same location and/or in the same color as on the preceding ...

Experimental investigation of the impact of optical injection on vital parameters of a gain-switched pulse source [PDF]

, 2007
An analysis of optical injection on a gain-switched distributed feedback (DFB) laser and its impact on pulse parameters that influence the performance of the pulse source in high-speed optical communication systems is presented in this paper.
