Color Knowledge Tied to Language-Visual Brain Circuitry

A new study shows that our ability to recall details about familiar objects—like a banana’s typical color—depends on strong connections between visual and language-processing areas of the brain. Researchers found that stroke patients with disrupted neural pathways between these regions had weaker object-color knowledge and altered brain activity.

Face Blindness Affects 1 in 50

A new study reveals that people with developmental prosopagnosia, or face blindness, struggle daily to recognize even close friends and family, despite having normal vision and memory. Many participants described coping strategies like keeping spreadsheets or using voices and clothing to identify others, but these are often exhausting and unreliable.

How Visual Neurons Adapt in Real Time

New research reveals that neurons in the visual cortex are far more adaptable than previously thought, responding dynamically to complex stimuli during object recognition tasks. While visual processing has traditionally been viewed as mostly feedforward, this study shows that feedback from higher brain areas conveys prior knowledge and behavioral context to shape perception.

This shows people surrounded by screens.

Brain Learns to Tune Out Distractions with Repeated Exposure

Our brains can adapt to filter out repeated distractions, according to a new EEG study. Participants learned to ignore frequent visual distractions, such as a red shape in the same location, while searching for a target.

Study Links Schizophrenia to Visual Contrast Sensitivity Deficits

People with schizophrenia experience impaired contrast perception, affecting their ability to differentiate light intensity and recognize shapes and textures. This deficit may stem from disruptions in glutamate neurotransmission, a key neural mechanism in the disease.

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."

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.

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.

Brain Processes Sentence Structures as Fast as Visual Scenes

The human brain can detect the structure of a short sentence in as little as 150 milliseconds, the speed of a blink. Using brain imaging, scientists found that the brain's language comprehension system processes sentences flashed on a screen similarly to how it perceives a visual scene.

How Visual Clutter Disrupts Information Flow in the Brain

A new study reveals that visual clutter alters how information flows between neurons in the brain’s primary visual cortex, but not the order in which it's processed. Researchers found that the efficiency of information transfer changes depending on the location of clutter in the visual field.

Neuroimaging Reveals How OPC Cells Shape Visual Processing

Researchers revealed the intricate role of OPC cells in shaping the brain's neural circuits. Previously known mainly for supporting neuron insulation, OPCs also prune unnecessary synaptic connections, refining the brain’s wiring as we accumulate experiences.

Serotonin Receptor Dampens Visual Input to Enhance Internal Processes

The 5-HT2A receptor in the brain reduces incoming visual information, allowing more space for internal thought processes. Researchers found that this receptor, when overactivated, suppresses sensory input, potentially explaining the effects of hallucinations from drugs like LSD.
