Shafaqna English- Young adults who spend at least an hour a day watching short-form videos show differences in how brain regions communicate at rest, according to a new study published in Frontiers in Human Neuroscience. Using functional MRI scans taken while participants were resting, the researchers examined activity within individual brain regions and communication between major brain networks. At the whole-brain level, frequent short-video users showed greater measures of network efficiency and clustering, with shorter communication pathways between brain regions. However, the researchers stress that greater connectivity or efficiency should not automatically be interpreted as brain damage. The study also did not test whether participants with greater short-video use actually performed better or worse on attention, memory or other cognitive tasks.
