Scientists Identified a Chemical Helping Us Suppress Undesired Thoughts
A team of scientists from the University of Cambridge has identified a chemical within the region of the brain responsible for memory that allows us to suppress undesired thoughts. This helps explain why people with anxiety, post-traumatic stress disorder (PTSD), depression, and schizophrenia often have persistent intrusive thoughts when these circuits go wrong.
In their study, the researchers used a task known as the ‘Think/No-Think’ procedure to identify a significant new brain process enabling the prefrontal cortex to successfully inhibit our thoughts.
Using functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy, the scientists managed to observe what was happening within the key regions of the brain as the participants tried to inhibit their thoughts. The researchers were able to measure brain chemistry with the help of spectroscopy.
