When the Brain's "Go Signal" Runs Low: Could Dopamine Explain Why the Mind and Body Slow Down Together? (Video Lay Summary OER)

This open educational resource (OER) accompanies the video lay summary, When the Brain’s “Go Signal” Runs Low: Could Dopamine Explain Why the Mind and Body Slow Down Together? It translates the complex neuroscience of psychomotor slowing into an accessible narrative, exploring whether reduced dopamine signalling may help explain shared slowing of movement, speech and thinking across Parkinson’s disease, depression and catatonia. The resource was developed in close collaboration with Dr Jonathan Rogers, an academic clinical psychiatrist at UCL with expertise in catatonia, neuropsychiatry and related brain–behaviour disorders. His specialist guidance helped ensure that the translation remained faithful to the underlying science. Dr Anja Harrison contributed substantially to the creation and development of the script and quality assessment checklist, helping to uphold both the scientific integrity and accessibility of the final resource. Her scientific insight, feedback and continued guidance supported the accurate, clear and meaningful communication of complex concepts to a wider audience. The resource brings together the video lay summary, full written lay summary, quality assessment materials and the original peer-reviewed scientific review, providing an accessible entry point for students, researchers, clinicians and members of the wider public interested in dopamine, psychomotor slowing and transdiagnostic neuroscience.
