The Role of Temporal and Spatial Attention in Size Adaptation
Frontiers in Neuroscience, 2020 One of the most important tasks for the visual system is to construct an internal representation of the spatial properties of objects, including their size.

Attentional Distribution and Spatial Language [PDF]
, 2014 Whether visual spatial attention can be split to several discontinuous locations concurrently is still an open and intensely debated question. We address this question in the domain of spatial language use by comparing two existing and three newly proposed computational models.

Revisiting Persistent Neuronal Activity During Covert Spatial Attention
Frontiers 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 ...

Spatial attention and the apprehension of spatial relations. [PDF]
Journal of Experimental Psychology: Human Perception and Performance, 1994 Seven experiments examined the role of spatial attention in apprehending spatial relations above, below, left, and right. In Experiment 1, visual search was difficult when targets differed from distractors only in the spatial relation between their elements. Reaction time increased linearly with display size with a slope greater than 60 ms/item.

The Retinotopy of Visual Spatial Attention [PDF]
Neuron, 1998 We used high-field (3T) functional magnetic resonance imaging (fMRI) to label cortical activity due to visual spatial attention, relative to flattened cortical maps of the retinotopy and visual areas from the same human subjects. In the main task, the visual stimulus remained constant, but covert visual spatial attention was varied in both location and

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

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