People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
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.
EEG and AI technology can directly decode the direction in which people are listening from brainwaves alone, without having to link them to direct sounds.
A dynamic interplay of different brainwave frequencies, not dedicated networks, governs how the brain acts to a novel surprise and downplays predictable stimuli.
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.
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.
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.
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.
Two activities support the brain's ability to establish reliable connections in the presence of significant biological background noise.
Hyperscanning reveals the brains of patients and musicians sync during music therapy.
Theta oscillations help the brain remember locations to which a person is trying to navigate.
Memory performance can be enhanced by rhythmic neural stimulation, using both invasive and non-invasive techniques.
