Brain Cells Tune to Multiple Rhythms Like a Neural Radio

New research reveals that individual neurons in the hippocampus can respond to both slow and fast brain waves at the same time by switching between different firing modes. This process, called interleaved resonance, allows brain cells to encode complex information by using bursts for slower theta waves and single spikes for faster gamma waves.

How Rhythm Rewires the Brain Moment by Moment

When you listen to a steady rhythm, your brain doesn’t just process it—it reconfigures itself in real time. A new study introduces FREQ-NESS, an advanced neuroimaging method that reveals how different frequencies of brainwaves form dynamic networks across the brain.

Spreading Brain Waves Drain Neuron Energy

Researchers have, for the first time, tracked how individual neurons lose and recover energy during spreading depolarizations — waves of electrical disturbance linked to brain disorders like stroke. Using genetically modified mice and real-time fluorescent microscopy, the team visualized adenosine triphosphate (ATP) levels in neurons under both healthy and stroke-like conditions.

Brain Wave Phase Locking May Be Key to Unconsciousness

Despite acting through different molecular mechanisms, ketamine and dexmedetomidine both disrupt brain wave phase alignment in ways that reliably induce unconsciousness. A new study reveals that these anesthetics trigger a common signature: increased phase locking at low frequencies, particularly between brain hemispheres, while disrupting local cortical communication.

Manipulating Brain Waves During Sleep With Sound

Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions. The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients' lives.

Sound Therapy May Improve Sleep

A new study reveals that stimulating alpha brain waves using sound may improve sleep in individuals with dementia. The technique, known as Alpha Closed-Loop Auditory Stimulation (aCLAS), can speed up or slow down alpha rhythms depending on the timing of the sound. This non-invasive approach could offer a new therapeutic avenue for sleep disturbances in dementia.

Brain Waves Influence How We Hear Words

A new study found that brain wave timing shapes our perception of speech. Researchers discovered that more probable sounds and words are perceived during less excitable brain wave phases, while less probable ones are noticed in more excitable phases.

Beta Rhythms May Be Master Regulators of Cognitive Control

A new study highlights the critical role of beta rhythms (14-30 Hz) in orchestrating cognitive processes. The research synthesizes experimental data and theoretical models to show that bursts of beta rhythms facilitate cognitive control by regulating the timing and location of higher-frequency gamma waves.

Hippocampus Generates Deep Sleep Waves

Scientists discovered a surprising new source for brain waves essential for deep sleep. These waves, traditionally thought to come from a different area, were also found to be generated by the hippocampus, a region crucial for memory.

Ripples of Recall: Brain Waves Play Key Role in Memory

Researchers have advanced our understanding of the neuronal basis of spatial memory. Their research reveals that during spatial memory tasks, different types of nerve cells activate in unison, coordinated by brain waves known as "ripples."

Studying Brain Oscillations to Understand What Makes a Memory Stick

Memory formation requires higher-frequency ripples in the hippocampus and lower-frequency ripples in the parietal cortex. However, to make a memory stick, coordinated high-frequency ripples between the hippocampus and parietal cortex are required.
