Targeted or Broadcast? How the Brain Processes Visual Information
Summary: 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…
Being Watched Changes How Your Brain Processes Faces
Summary: 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…
Visual Silence: Exploring Aphantasia – Neuroscience News
Summary: 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…
Reduced Brain Response to Visual Cues Linked to Psychosis in Parkinson’s
Summary: People with Parkinson’s disease (PD) who experience visual hallucinations have reduced brain responses to unexpected visual changes, a marker known as visual mismatch negativity (vMMN). Using EEG, researchers compared…
Serotonin Receptor Dampens Visual Input to Enhance Internal Processes
Summary: 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…
Childhood Vision Loss Affects Sound Distance Judgement
Summary: New research reveals that individuals who experience vision loss before age 10 struggle more with judging sound distance compared to those who lose sight later in life. This difficulty…
How Our Brain Deciphers Gaze Direction
Summary: A new study reveals the precise moment the brain detects gaze direction, enhancing our understanding of social interactions and disorders like autism and Alzheimer’s. Researchers used EEG and machine…
