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…
Women Scan For Danger When Walking at Night
Summary: A new study highlights the stark differences in how men and women perceive safety while walking at night. Through an innovative use of heat maps generated by participants’ focus…
Eating with Your Eyes and Gut? How Your Brain Decides When to Eat
Summary: The science of eating behavior goes beyond hunger cues; it involves sensory stimuli, internal signals, and the gut-brain connection. External cues like food packaging and advertisements influence our eating…
Enhancing Motor Learning with Visual-Motor Illusions
Summary: Researchers found that visual aids creating illusions of movement, like screens showing a hand’s motion, can enhance motor performance and early-stage motor learning. Functional near-infrared spectroscopy revealed distinct brain…
