The Brain HelpDesk

In a digital era defined by an overwhelming abundance of information (both accurate and misleading), the need for accessible, trustworthy scientific information has become increasingly important. To strengthen the dialogue between neuroscientists and the general public, we launched the Brain HelpDesk (BHD), an online platform where non-scientists can submit questions related to the brain and receive clear, accessible, and scientifically grounded answers. This paper offers a practical guide for researchers interested in creating similar initiatives. We position the BHD in the current science communication landscape and describe our workflow design, standardised answer template, and the geographic spread of our audience. The questions we have received and addressed so far highlight the public's interest in fundamental and mechanistic over more pathology-focused topics. Based on our own experience, we recommend (1) using a clear and consistent answer format, (2) starting with a small dedicated team, (3) designing a user-friendly, yet privacy-minded website, (4) having both an online and (5) in-person presence, (6) creating a structured workflow and (7) using institutional support to boost both visibility and credibility. With this paper, we aim to inspire and support fellow scientists in launching their own scientific helpdesks, fostering dialogue and making science more accessible and understandable to everyone.
