Researchers Observe New Complexity of Traveling Brain Waves in Memory Circuits

A new micro-grid recording device allowed researchers to measure hippocampal activity in epileptic patients. They found brain waves travel back and forth across the brain structure, integrating messages from different areas of the brain.

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.

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.

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.

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.
