AI Article Synopsis

  • - The study aimed to explore how eye movement patterns change based on the presence of color in images, with 40 participants viewing both colored and grey-scale pictures.
  • - Findings revealed that, despite colored images being more complex, people spent less time looking at them compared to grey-scale images, indicating that color helps in distinguishing details more quickly.
  • - Additionally, color usage led to greater variation in where different participants looked, highlighting that color significantly influences visual attention more than previously thought.

Article Abstract

The aim of this study was to investigate how oculomotor behaviour depends on the availability of colour information in pictorial stimuli. Forty study participants viewed complex images in colour or grey-scale, while their eye movements were recorded. We found two major effects of colour. First, although colour increases the complexity of an image, fixations on colour images were shorter than on their grey-scale versions. This suggests that colour enhances discriminability and thus affects low-level perceptual processing. Second, colour decreases the similarity of spatial fixation patterns between participants. The role of colour on visual attention seems to be more important than previously assumed, in theoretical as well as methodological terms.

Delayed Progression of Ataxia with a Static Cerebellar Lesion- Consider SCA27B.

Cerebellum

Department of Neurology, Donders Institute for Brain, Cognition & Behaviour, Radboud University Medical Center, Nijmegen, The Netherlands.

Repeat expansions in the fibroblast growth factor 14 gene (FGF14), associated with spinocerebellar ataxia type 27B (SCA27B), have emerged as a prevalent cause of previously unexplained late-onset cerebellar ataxia. Here, we present a patient with residual symptom of gait ataxia after complicated meningioma surgery, who presented with progressive symptoms of oculomotor disturbances, speech difficulties, vertigo and worsening of gait imbalance, twelve years post-resection. Neuroimaging revealed a surgical resection cavity in the dorsolateral side of the left cerebellar hemisphere, accompanied by gliosis in left cerebellar hemisphere extending into the vermis, extensive non-specific supratentorial periventricular white matter abnormalities, and mild atrophy of the cerebellar vermis.

Subsets of extraocular motoneurons produce kinematically distinct saccades during hunting and exploration.

Animals construct diverse behavioral repertoires by moving a limited number of body parts with varied kinematics and patterns of coordination. There is evidence that distinct movements can be generated by changes in activity dynamics within a common pool of motoneurons or by selectively engaging specific subsets of motoneurons in a task-dependent manner. However, in most cases, we have an incomplete understanding of the patterns of motoneuron activity that generate distinct actions and of how upstream premotor circuits select and assemble such motor programs.

To maintain stable vision, behaving animals make compensatory eye movements in response to image slip, a reflex known as the optokinetic response (OKR). Although OKR has been studied in several avian species, eye movements during flight are expected to be minimal. This is because vertebrates with laterally placed eyes typically show weak OKR to nasal-to-temporal motion (NT), which simulates typical forward locomotion, compared with temporal-to-nasal motion (TN), which simulates atypical backward locomotion.

How are arbitrary sequences of verbal information retained and manipulated in working memory? Increasing evidence suggests that serial order in verbal WM is spatially coded and that spatial attention is involved in access and retrieval. Based on the idea that brain areas controlling spatial attention are also involved in oculomotor control, we used eye tracking to reveal how the spatial structure of serial order information is accessed in verbal working memory. In two experiments, participants memorized a sequence of auditory words in the correct order.
