00:00Scientists may have found a clue that could make brain stimulation more reliable.
00:04A new study suggests the brain's activity, just before stimulation, can influence how strongly it responds.
00:10Researchers analyzed brain recordings from 36 people with epilepsy.
00:14The data covered about 320 sessions and more than 10,000 individual stimulations.
00:20Scientists examined 125 different measures of brain activity before each stimulus.
00:26These included brain synchronization, connectivity, and signal complexity.
00:30The researchers found that whole brain activity was more informative than signals from one local area.
00:37The strongest predictions were seen when stimulation targeted visual and sensorimotor networks.
00:42When specific pre-stimulation brain patterns were selected, response variability fell by as much as 24%.
00:49The patterns appeared in both intracranial and scalp EEG recordings.
00:53That could eventually allow doctors to monitor brain activity in real time.
00:58Researchers say this approach may help make neuromodulation treatments more precise and predictable.
