Why People Are Better at Guessing the Past Than Predicting the Future

A new study shows that people are better at inferring past events than predicting future ones when watching scenes from TV dramas. The researchers found that participants were more accurate in guessing what had happened earlier in the story because characters tend to talk about their pasts more often than their futures.

Serotonin Levels Rise With Reward Anticipation

Serotonin, known as the "happiness molecule," increases in anticipation of a reward and scales with the value of that reward. Using a biosensor called GRAB-serotonin, researchers measured serotonin in real time in mice as they received treats.

New Brain Template Created

Researchers have developed "OpenNeuro Average" (onavg), a new cortical surface template that improves the accuracy and efficiency of neuroimaging data analysis. This template is based on 1,031 brains, providing a more uniform and less biased map compared to previous models.

How the Brain Regulates Emotion

A new study provides a novel understanding how the human brain regulates emotions, distinguishing between emotion generation and regulation. By analyzing fMRI studies, researchers identified specific brain regions, including areas of the anterior prefrontal cortex, that are key to emotion regulation.

Aging Brain Cells Have Prolonged Death Process

Mature oligodendrocytes, crucial for brain function and myelin production, have an unusually prolonged death process after damage, surviving up to 45 days post-trauma, a stark contrast to the rapid demise of their younger counterparts within 24 hours. This study illuminates a previously unknown pathway of cell longevity, suggesting a potential shift in strategies for treating aging-related damage and neurodegenerative diseases like multiple sclerosis.

Devil in the Details: The Visual World of Prosopometamorphopsia

Researchers conducted a pioneering study on prosopometamorphopsia (PMO), a rare condition where individuals perceive facial features as distorted. The study details the unique case of a 58-year-old male who experiences facial distortions exclusively in person, not when viewing images on screens or paper, allowing researchers to create accurate visualizations of his perceptions.

Meaningful Stimuli: The Key to Expanding Visual Memory Capacity

Researchers discovered our capacity for visual working memory is not rigid, but can be expanded when stimuli are meaningful. Traditional theories proposed that the capacity for visual working memory, crucial for various cognitive abilities, was fixed.

The Key to Debunking False Beliefs Is by Addressing Underlying Belief Systems

A new study suggests that to debunk false beliefs, it may be more effective to target a person's system of beliefs rather than trying to change the false belief itself. The study found that people have a system of interrelated beliefs that depend on each other and may anchor their system, making it difficult to change beliefs even with evidence against them.
