Multifocal Lenses Reduce Myopia Risks

New research demonstrates that high-add multifocal contact lenses significantly slow myopia progression in children, with benefits that persist even after discontinuation. The lenses, designed to slow eye growth and reduce long-term myopia-related risks, showed no rebound effect after treatment stopped.

This shows the outline of a head and a brain.

Brain Merges Sight and Sound to Understand Speech in Noisy Settings

Researchers are investigating how the brain combines visual and auditory cues to improve speech comprehension in noisy environments. The study focuses on how visual information, like lip movements, enhances the brain's ability to differentiate similar sounds, such as "F" and "S."

Pupil Dynamics During Sleep Reveal Brain’s Memory-Saving Secrets

Researchers have discovered that pupil size during non-REM sleep correlates with memory consolidation. When pupils contract, the brain focuses on consolidating new memories; when dilated, it processes older ones.

Ancient Brain Reflex Develops Without Sensory Input

Researchers uncovered that the vestibulo-ocular reflex, a vital brain circuit stabilizing gaze during body tilts, matures independently of sensory input in newborns. This reflex, essential for perceiving a stable environment, enables the eyes to counter-rotate with body movements.

Genes Behind Dyslexia Linked to Brain Changes in Motor, Vision, and Language

A large-scale study revealed that genetic variants linked to dyslexia are associated with differences in brain areas controlling motor coordination, vision, and language. Using data from over a million individuals, researchers calculated genetic "polygenic scores" for dyslexia and analyzed their relationship to brain structures. Higher genetic risk for dyslexia was tied to lower volumes in brain regions related to speech processing and movement, and increased volumes in the visual cortex.

Study Ties Visual Errors to Paranoid Beliefs

A new study suggests complex beliefs like paranoia may have roots in visual misperception. Participants prone to paranoia or teleological thinking were more likely to wrongly identify one moving dot as chasing another in a visual task.

Targeted or Broadcast? How the Brain Processes Visual Information

Researchers have uncovered how visual information is processed across the brain’s complex and flexible networks. One study showed visual signals are selectively targeted or broadly broadcast, challenging the idea of a simple, linear flow of visual input.

Being Watched Changes How Your Brain Processes Faces

A new study shows that knowing you're under surveillance triggers a faster, automatic brain response to detect faces and gaze direction. Researchers found that participants monitored via CCTV became hyper-aware of facial stimuli nearly a second faster than those not being watched, even without realizing it.

Visual Silence: Exploring Aphantasia

A new study reveals that aphantasics, people unable to visualize, are more resistant to involuntary visual thoughts, such as imagining a pink elephant. While vivid visual imaginations often lead to intrusive imagery, aphantasics seem to redirect their thoughts to other mental processes, like abstract ideas or auditory daydreaming.

Why Autistic Children View Faces Differently

Children with autism exhibit distinct eye movement patterns when viewing faces, particularly in the initial stages of visual processing. A new study found that autistic children are more likely to use an exploratory eye movement pattern, focusing on broader areas rather than immediately fixating on facial features. This behavior may be linked to reduced visual sensitivity to social cues and is associated with autism-related challenges in social communication.

How the Brain Sorts Noise from Signal to Maintain Stable Perception

New research reveals how the brain separates internally generated noise from sensory signals, ensuring stable perception. The study shows that in lower visual areas, spontaneous brain activity and stimulus-evoked responses are similar, but in higher cortical areas, they become increasingly independent, a process known as orthogonalization.

Sleep Apnea May Increase Risk of Wet Macular Degeneration

A new study has linked moderate-to-severe obstructive sleep apnea (OSA), characterized by low oxygen levels overnight, with an increased risk of developing wet age-related macular degeneration (AMD). The research suggests nocturnal hypoxia could affect the oxygen-sensitive retina, contributing to AMD progression.
