AI Article Synopsis
- Evaluation of eye movements is crucial for understanding neurological disorders, but assessing children poses challenges due to developmental changes and lack of standard data.
- A study analyzed smooth pursuit eye movements in 65 children aged 7-11 years, revealing that horizontal smooth pursuit (HSP) was more effective than vertical smooth pursuit (VSP).
- The difference in effectiveness between HSP and VSP appeared to lessen with age, indicating that the networks controlling VSP mature later than those for HSP in certain brain regions.
Article Abstract
An evaluation of eye movements is very useful in neurological disorders but is complicated by issues such as maturation and lack of normative data in children. In order to address these issues we studied smooth pursuit eye movements of 65 normal children aged 7-11 years old. The gain of horizontal smooth pursuit (HSP) was higher than the gain of the vertical smooth pursuit (SP) and this difference had a statistical tendency to disappear with aging from 7 to 11 years. These data suggest that, in the cerebral regions involved in the control of SP, i.e. posterior parietal and superior temporal lobe regions, the networks for VSP mature latter than those for HSP.

Achieving atomic-level characterization of the diamond (001) surface has been a persistent goal over recent decades. This pursuit aims to understand the smooth growth of diamonds and investigate surface defects and adsorbates relevant to applications. However, the inherently low conductivity and the short C-C bonds present significant challenges for atomic resolution imaging.

Background: Eye movement research serves as a critical tool for assessing brain function, diagnosing neurological and psychiatric disorders, and understanding cognition and behavior. Sex differences have largely been under reported or ignored in neurological research. However, eye movement features provide biomarkers that are useful for disease classification with superior accuracy and robustness compared to previous classifiers for neurological diseases.

Sensory-motor systems can extract statistical regularities in dynamic uncertain environments, enabling quicker responses and anticipatory behavior for expected events. Anticipatory smooth pursuit eye movements (aSP) have been observed in primates when the temporal and kinematic properties of a forthcoming visual moving target are fully or partially predictable. To investigate the nature of the internal model of target kinematics underlying aSP, we tested the effect of varying the target kinematics and its predictability.
