Summary: For decades, neuroscience textbooks have taught that the first stage of visual processing relies on two types of cells specialized in detecting “edges”—sharp transitions between light and dark. However,…

How Invasive Moths Use Magnetic and Visual Cues to Migrate
Summary: Billions of moths navigate the night sky every year, moving across entire continents with uncanny precision. A new study has uncovered how one of the world’s most invasive pests—the…
Numbers in Vision Can Shift How We Perceive Space
Summary: New research reveals that numbers in our visual field can subtly distort how we judge spatial positions, showing that perception is shaped by both numerical magnitude and object-based processing.…
Cues Can Hijack Decision Making in Some People
Summary: Some individuals rely heavily on visual and sound cues when making decisions, and this sensitivity can lead to persistent maladaptive choices. When cue–outcome associations shift, these individuals struggle to…
Brain Decoder Translates Visual Thoughts Into Text
Summary: A new brain decoding method called mind captioning can generate accurate text descriptions of what a person is seeing or recalling—without relying on the brain’s language system. Instead, it…
New Therapy Reshapes Images That Fuel Psychosis
Summary: A new imagery-focused therapy called iMAPS may help people with psychosis gain control over disturbing mental images that fuel paranoia, fear, and hallucinations. In a feasibility trial of 45…
Brain Reveals Attention Works Like a Zoom Lens
Summary: A new study shows that our brain’s attention system first prepares broadly, then zooms in on specific details within fractions of a second. Using EEG and machine learning, researchers…
Promise of Reward Changes How We Pay Attention
Summary: A new study reveals that our brains treat sensitivity and decision bias as separate processes when rewards are at stake. Using eye-tracking and EEG during a visual task, researchers…
Blurry Beginnings Shape Brain’s Visual Pathways
Summary: New research reveals how early-life blurry, low-color vision may help shape the brain’s visual pathways into specialized systems. Using computational models trained on low-quality images followed by high-quality ones,…
