Out-of-sync brain waves may underlie learning deficit linked to schizophrenia

Study reveals specific brain wave patterns that underlie the ability to remove irrelevant learned associations to make way for new, updated information. The research shows a particular behavior can be dependent on the synchronization of high-frequency brain waves in different parts of the brain. Read More

Brief bursts, big insights

A new method for analyzing brain oscillation data can detect short beta wave bursts in real-time within neural frequency bands of 20 Hertz. The method also shows how rats can increase the occurrences of these bursts. Read More

Ayahuasca DMT compound changes brainwaves to vivid ‘waking-dream’ state

DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness. Read More

Epilepsy: Seizures not forecastable as expected

A new study challenges the belief that epileptic seizures can be predicted by brain wave patterns. Researchers report they have found no evidence that specific brain wave patterns can be a predictive indicator of seizure onset. Read More

VA-led study of combat personnel with brain injuries pinpoints abnormal brain waves

Neuroimaging study reveals veterans who suffered a mild traumatic brain injury (mTBI) have higher levels of fast, high-frequency gamma waves in the prefrontal and posterior parietal lobes, areas of the brain associated with consciousness, attention and problem-solving. Read More
