Visual attention network

MH Guo, CZ Lu, ZN Liu, MM Cheng, SM Hu - Computational Visual Media, 2023 - Springer
While originally designed for natural language processing tasks, the self-attention
mechanism has recently taken various computer vision areas by storm. However, the 2D …

Separable processes for live “in-person” and live “zoom-like” faces

N Zhao, X Zhang, JA Noah, M Tiede… - Imaging Neuroscience, 2023 - direct.mit.edu
It has long been understood that the ventral visual stream of the human brain processes

A dual-stream neural network explains the functional segregation of dorsal and ventral visual pathways in human brains

M Choi, K Han, X Wang, Y Zhang… - Advances in Neural …, 2023 - proceedings.neurips.cc
The human visual system uses two parallel pathways for spatial processing and object
recognition. In contrast, computer vision systems tend to use a single feedforward pathway …

Feature-specific salience maps in human cortex

DD Thayer, TC Sprague - Journal of Neuroscience, 2023 - Soc Neuroscience
Priority map theory is a leading framework for understanding how various aspects of
stimulus displays and task demands guide visual attention. Per this theory, the visual system …

Top-down control of exogenous attentional selection is mediated by beta coherence in prefrontal cortex

A Dubey, DA Markowitz, B Pesaran - Neuron, 2023 - cell.com
Salience-driven exogenous and goal-driven endogenous attentional selection are two
distinct forms of attention that guide selection of task-irrelevant and task-relevant targets in …

[HTML][HTML] Towards reliable object representation via sparse directional patches and spatial center cues

M Jian, H Yu - Fundamental Research, 2023 - Elsevier
In the process of image understanding, the human visual system (HVS) performs multiscale
analysis on various objects. HVS primarily focuses on marginally conspicuous image …

[HTML][HTML] Eye movement evidence for the V1 Saliency Hypothesis and the Central-peripheral Dichotomy theory in an anomalous visual search task

J Liang, S Maher, L Zhaoping - Vision Research, 2023 - Elsevier
Typically, searching for a target among uniformly tilted non-targets is easier when this target
is perpendicular, rather than parallel, to the non-targets. The V1 Saliency Hypothesis (V1SH) …

Functional imaging and anatomical connections in squirrel monkeys reveal parietal–frontal circuits underlying eye movements

I Stepniewska, S Kahler-Quesada, JH Kaas… - Cerebral …, 2023 - academic.oup.com
The posterior parietal cortex (PPC) of squirrel monkeys contains subregions where long
trains of intracortical microstimulation evoke complex, behaviorally meaningful movements …

Dynamic spatial coding in parietal cortex mediates tactile-motor transformation

J Klautke, C Foster, WP Medendorp, T Heed - Nature Communications, 2023 - nature.com
Movements towards touch on the body require integrating tactile location and body posture
information. Tactile processing and movement planning both rely on posterior parietal cortex …
