- Protocol
- SMR (sensorimotor rhythm) EEG biofeedback
Key findings
- SMR over sensorimotor cortex resembles sleep spindles and accompanies learned motor inhibition
- SMR training in cats and monkeys produced an unexpected anticonvulsant effect on drug-induced seizures
- Studies in people with epilepsy documented significant reductions in seizure frequency and severity, with EEG normalization
- Findings were extended internationally in controlled group and single-case studies summarized in meta-analyses
A review tracing EEG biofeedback (operant conditioning of brain rhythms) from animal research to a treatment option for seizure disorders. Work on behavioral inhibition revealed the sensorimotor rhythm (SMR, 12-15 Hz), and training it in animals unexpectedly protected against drug-induced seizures. Human studies followed, and the author describes later controlled work, imaging findings that may explain the effects, and the methods used in his own biofeedback program.
