Keeping Your Attention

Activity of the brain stem area 'locus coeruleus' controls goal-directed behaviour and attention

Keeping Your Attention

As you may have experienced in 2020 when working from home, maintaining your attention comes down to the capacity to ignore distractions while controlling impulses to do something else. These two abilities, although operated independently, can be traced to one area of the brainstem called the locus coeruleus (LC). A team of scientists recently showed how distractibility and impulsivity are controlled by LC neurons that target separate regions of the prefrontal cortex. The team were able to demonstrate this in mice in real-time using optogenetics, a technique that uses light and the light-sensitive protein channelrhodopsin to control the electrical signals neurons use to communicate. Here, we see LC neurons (in purple) expressing channelrhodopsin (in green). The ability to control the neural pathways for distractibility and impulsivity could in future lead to new treatments that tackle conditions where these abilities are impaired, such as attention deficit hyperactivity disorder (ADHD).

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
