Eye saccades enable mammals to chase prey and navigate through complex environments by aligning with optic flow, reducing motion blur. This mechanism allows animals to track erratic movements and react flexibly to changes in direction.
A study found that people's eyes are drawn to areas with high potential for change before any movement occurs, even when the scene appears static. This behavior is not limited to animate objects and has significant implications for intelligent machines.
Researchers from École de Technologie Supérieure and Dartmouth University are investigating the use of earpiece microphones to spot early signs of Alzheimer’s. They aim to develop health-monitoring algorithms for hearables capable of continuous, long-term monitoring and early disease detection.
A study by the University of Münster's research team led by Prof Markus Lappe found that smooth eye movements cannot be performed for all types of visual motion, leading to a disruption of spatial perception. The researchers also discovered that the compensation mechanism for rapid eye movements is overridden when certain non-rigid mov...
A new AI system uses artificial neural networks to recognize objects more accurately and stably, despite changing visual inputs. The system mimics human eye movements to improve machine vision capabilities, reducing errors in self-driving cars and other applications.
Researchers found that batters keep their eye on the ball but move their head to direct their gaze. The study suggests that this movement may help reduce visual calculations needed for accurate bat placement. Further investigation is needed to determine if eye-gaze-based training can improve batting performance.
Researchers at the University of Alabama at Birmingham have identified a novel population of neurons, called saccade-vergence burst neurons (SVBNs), that control disjunctive saccades in 3D space. These findings could lead to new treatments for strabismus, a condition where eyes don't properly align.
A study by Tohoku University's Research Institute of Electrical Communication reveals that visual stability across saccades occurs when parvo-pathway signals suppress magno-pathway signals immediately after a saccade. This finding has implications for AI and robots to perceive the world as humans do.
Researchers have developed a novel method enabling infinite walking in VR by manipulating user eye movements during saccadic suppression. The system successfully redirects users away from obstacles in the physical space while avoiding scene distortions.
A University of Pittsburgh bioengineer uses experimental and computational approaches to study the neural mechanisms of eye movements directed to stationary and moving objects. The team records activity in neurons of the superior colliculus to understand how the brain processes visual information during saccadic eye movements.
A study found that individuals with ADHD showed different patterns of eye movements compared to neurotypical individuals, indicating difficulties with predicting and reacting to upcoming events. This suggests the use of eye movements as an objective measure of temporal expectation, potentially complementing existing diagnostic tools.
Researchers at NYU Langone Health found that non-native English speakers performed slower on sideline vision tests and had higher saccade rates compared to native English speakers. The study suggests that clinicians and trainers need to consider language when interpreting test results, which may impact concussion detection.
Research by Dr. Christopher Pack suggests brain activity oscillations have a role in resetting sensitivity of neurons after eye movements and supporting representation of space. These patterns allow for rapid neural communication across different spatial positions.
Research reveals that Chinese ethnicity is a stronger factor than culture in determining eye movement patterns, contrary to previous reports. The study found that similar numbers of British Chinese and mainland Chinese participants made high numbers of express saccades.
Researchers found a strong correlation between fast eye movements and impulsivity in decision-making. The study suggests that people who make quick decisions may have a different way of evaluating time and reward in their brains.
Researchers have found a brain mechanism that coordinates eye and arm movements, which may have implications for rehabilitation and prosthetics. The study used macaque monkeys to examine the neurological activity of the posterior parietal cortex, finding coherent patterns of firing in regions specialized for moving eyes or arms.
Researchers have developed a novel biometric authentication method based on human reflexes, which cannot be replicated or spoofed by malicious individuals. By tracking blind spot position and saccade responses, this approach provides unique identification for each user.
Researchers at UCLA discovered that fruit flies integrate visual and olfactory information to track odors, using visual markers to navigate through complex environments. This crossmodal integration enables flies to efficiently find food despite their limited sensory capabilities.
Researchers Robert Schafer and Tirin Moore studied how the frontal eye field generates saccades, finding that attentional circuitry governs motor circuitry. The study used eyetracking and microstimulation to analyze saccade patterns, revealing a mechanism for attention to modulate saccade motor commands.
Pitt and NIH researchers provide a circuit-level explanation for why our eyes appear to move smoothly despite making saccades. They found that a corollary discharge signal from the brainstem causes visual neurons to shift their receptive field, enabling visual stability.
Researchers discovered that younger people struggle to ignore secondary targets due to an undeveloped frontal cortex, leading to rapid eye movements and multiple saccades. This study may hold clues for understanding developmental delays in cerebral palsy patients.
Researchers evaluated saccadic performance in adults with a family history of alcoholism, finding they were slower than those without a history. The study suggests that adaptive response to alcohol is associated with a family-history status known to be associated with genetic influence on alcoholism risk.
