Involvement of the dorsal and ventral attention networks in visual attention span

Abstract

Visual attention span (VAS), which refers to the window size of multielement parallel processing in a short time, plays an important role in higher-level cognition (e.g., reading) as required by encoding large amounts of information input. However, it is still a matter of debate about the underlying neural mechanism of VAS. In the

Impaired brain networks functional connectivity after acute mild hypoxia

“…[ 29 ] The ventral AN has been shown to be involved in visual attention span; that is, the stimulus-evoked attention significantly activates the ventral AN to reorient the visuospatial attention. [ 30 ] A possible explanation for our finding is the decreased perception of endogenous and exogenous stimuli after hypoxia exposure. Overall, decreased functional connectivity may reflect impaired cognitive function of pilots after hypoxia exposure, and such findings seem to provide valuable insights into understanding the psychophysiological mechanisms of flying.…”

Functional connectivity across dorsal and ventral attention networks in response to task difficulty and experimental pain

“…Figure 5c also revealed the left IPS to be the most significant hub of activity, acting as a destination for top-down, interhemispheric pathways and serving as source for bottom-up pathways to the right hemisphere. There is evidence of the left IPS serving a pivotal role in the coordination of DAN and VAN during a study of visual attention span (Zhao et al, 2022), and while some have focused on connectivity in the right hemisphere between IPS and TPJ (Wen et al, 2012), others have argued for greater consideration of left hemispheric areas as potential nodes and hubs in the DAN/VAN dichotomy (Mengotti et al, 2020;Vossel et al, 2012). In our case, it is important to note that our participants were right-handed and used the right thumb to play the game, hence it is possible that the prominence of the left IPS during high difficulty gaming resulted from contralateral activation.…”

The brain‐derived neurotrophic factor Val66met polymorphism is associated with better attention and working memory performance and resilience to mild chronic stress

“…The ventral attention network is important for inhibition and filtering out distractors but is suppressed during multi‐elemental tasks (Zhao et al, 2022), whereas the dorsal attention network is related to spatial attention and working memory (Vossel et al, 2014; Zhao et al, 2022). It is likely that the more complex measures of decision‐making, working memory and visual learning require more dynamic attentional control than the attention measure (simple reaction time) and therefore would rely on the dorsal attention network while suppressing the ventral attention network.…”
