Revisiting Persistent Neuronal Activity During Covert Spatial Attention

open access: yesFrontiers in Neural Circuits, 2021
Persistent activity has been observed in the prefrontal cortex (PFC), in particular during the delay periods of visual attention tasks. Classical approaches based on the average activity over multiple trials have revealed that such an activity encodes ...

The time course of spatial attention shifts in elementary arithmetic [PDF]

open access: yes, 2017
It has been proposed that elementary arithmetic induces spatial shifts of attention. However, the timing of this arithmetic-space association remains unknown. Here we investigate this issue with a target detection paradigm. Detecting targets in the right

Spatial distribution of attentional modulation at columnar resolution in macaque area V4

open access: yesFrontiers in Neural Circuits, 2016
Attention to a location in a visual scene affects neuronal responses in visual cortical areas in a retinotopically specific manner. Optical imaging studies have revealed that cortical responses consist of two components of different sizes: the stimulus ...

iEnhancer-DCSV: Predicting enhancers and their strength based on DenseNet and improved convolutional block attention module

open access: yesFrontiers in Genetics, 2023
Enhancers play a crucial role in controlling gene transcription and expression. Therefore, bioinformatics puts many emphases on predicting enhancers and their strength.

Paying attention to working memory: similarities in the spatial distribution of attention in mental and physical space [PDF]

open access: yes, 2016
Selective attention is not limited to information that is physically present in the external world, but can also operate on mental representations in the internal world.

Top-Down Control of Visual Attention by the Prefrontal Cortex. Functional Specialization and Long-Range Interactions

open access: yesFrontiers in Neuroscience, 2017
The ability to select information that is relevant to current behavioral goals is the hallmark of voluntary attention and an essential part of our cognition. Attention tasks are a prime example to study at the neuronal level, how task related information

Noise Exclusion in Spatial Attention [PDF]

open access: yesPsychological Science, 2000
Precue validity affects the performance of perceptual tasks. These spatial attention effects have been variously attributed to facilitation of processing, capacity allocation, or noise reduction. We used a new attention-plus-external (stimulus)-noise paradigm and model to identify the mechanisms of attention in cue-validity paradigms. A new phenomenon

Decoding Adaptive Visuomotor Behavior Mediated by Non-linear Phase Coupling in Macaque Area MT

open access: yesFrontiers in Neuroscience, 2020
The idea that a flexible behavior relies on synchronous neural activity within intra- and inter-associated cortical areas has been a matter of intense research in human and animal neuroscience. The neurophysiological mechanisms underlying this behavioral

Spatial judgment in Parkinson's disease: Contributions of attentional and executive dysfunction [PDF]

open access: yes, 2019
Spatial judgment is impaired in Parkinson's disease (PD), with previous research suggesting that disruptions in attention and executive function are likely contributors.

Right-lateralised lane keeping in young and older British drivers [PDF]

open access: yes, 2018
Young adults demonstrate a small, but consistent, asymmetry of spatial attention favouring the left side of space (“pseudoneglect”) in laboratory-based tests of perception.
