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.

Great Apes’ Gaze Reveals Human-Like Event Perception

Great apes track events involving agents and patients, like humans, suggesting shared cognitive mechanisms. When watching video clips, apes alternated their gaze between agents (e.g., a cat) and patients (e.g., a mouse), similar to adult humans, though apes paid more attention to background details.

How Expectations Shape Our Gaze in a Changing World

Our expectations about potential changes in a scene influence how we move our eyes, even when viewing static images. Participants looked more at areas with a high "potential for change" (PfC)—such as objects likely to move—when they expected the scene to become dynamic, despite no motion occurring during the observation period.

Brainstem Neurons Guide Gaze, Maintain Short-Term Memory

Researchers used zebrafish larvae to uncover how brainstem neurons guide gaze and maintain short-term memory. By mapping neuronal circuits, they built a computational model that accurately predicted network activity. The findings shed light on visual-motor systems and offer insights for treating eye movement disorders.

Earpiece Tech Detects Early Alzheimer’s Through Eye Movement Signals

Researchers are exploring how earpiece microphones, or "hearables," could detect early signs of Alzheimer’s disease by monitoring subtle eye movement changes. Alzheimer’s impacts motor and cognitive functions, with slowed or delayed eye movements (saccades) being an early indicator.
