A new study of high school football players found that concussions affect an often-overlooked but important brain signal.
Radiological Society of North AmericaNov 26 2024 The findings are being presented next week at the annual meeting of the Radiological Society of North America .
Most previous neuroscience research has focused on rhythmic brain signaling, which is also called periodic neurophysiology. On the other hand, aperiodic neurophysiology refers to brain signals that are not rhythmic." "While it's often overlooked, aperiodic activity is important because it reflects brain cortical excitability," said study senior author Christopher T. Whitlow, M.D., Ph.D., M.H.A., Meschan Distinguished Professor and Enterprise Chair of Radiology at Wake Forest University School of Medicine.
Pre- and post-season resting-state magnetoencephalography data was collected from 91 high school football players, of whom 10 were diagnosed with a concussion. MEG is a neuroimaging technique that measures the magnetic fields that the brain's electrical currents produce. Slowed aperiodic activity was present in areas of the brain that contain chemicals linked with concussion symptoms like impaired concentration and memory.
The findings from the study may also influence tracking of post-concussion symptoms and aid in finding new treatments to improve recovery.
