- New Study Links Reward and Aggression through Brain Chemistryby Samer SiwaniNews, Could our urge to fight actually feel rewarding? A study published in Nature Communications suggests yes, and serotonin may hold the key to stopping it. Most of us know that dopamine is involved in reward because of addiction research, and we know that serotonin can regulate emotions, as evidenced by the effects of antidepressants… Read more: New Study Links Reward and Aggression through Brain Chemistry
- Scientists rewire fear: How Transcranial Stimulation Can Turn Danger Into Safetyby Samer SiwaniNews, A recent study out of Dortmund, Germany has found that transcranial stimulation of a brain region in the prefrontal cortex can change the brain’s view of a perceived danger as safe. In this study, researchers recorded brain activity in healthy individuals with an MRI machine, while they underwent a conditioning task. In the task,… Read more: Scientists rewire fear: How Transcranial Stimulation Can Turn Danger Into Safety
- Is your brain older than you? It can now be predicted by AI with 3-year precisionby Samer SiwaniNews, In a recent study published in Scientific Reports, researchers in Egypt trained a deep learning model to predict brain age. They applied a spatial and temporal analysis on MRI datasets to map anatomical features and how they change over time. This model, they report, outperforms others in error margin, achieving a lower Mean Absolute… Read more: Is your brain older than you? It can now be predicted by AI with 3-year precision
