Neural oscillations research, explained
8 open-access neural oscillations studies, each with a flashcard deck and a quiz.
- Boosting short-term memory by slowing down brain waves
Slowing down a person's individual theta brain wave frequency using electrical stimulation temporarily increases how much information they can hold in their short-term memory.
- Can timing brain stimulation suppress Parkinson's beta waves?
Timing electrical pulses to match specific points of a patient's abnormal brain waves can successfully dampen those waves.
- How does mindfulness meditation quiet the neural sense of self?
By directing their attention, experienced meditators can turn down distinct brain networks that produce our everyday sense of identity and immediate physical experience.
- How do alpha brain waves help us hear speech in noisy rooms?
Paying attention to speech in noise triggers alpha brain wave suppression in the auditory cortex, which directly predicts how well a listener understands the words.
- Does ketamine model brain activity changes in schizophrenia?
Although S-ketamine mimics schizophrenia symptoms, it triggers the opposite effects on brain wave intensity and connectivity compared to patients.
- Can brain stimulation reduce anxiety long-term?
Repetitive rhythmic electrical stimulation of the brain's visual areas reduces anxiety and strengthens long-distance brain networks over several days.
- Connecting the brain's mu rhythm to multiple neural networks
The brain's sensorimotor mu rhythm is linked to several different neural networks, showing it is not just a simple indicator of movement control.
- How Brain Stimulation Affects Risky Choices
Applying 20-Hz electrical stimulation to the left prefrontal cortex increases a person's willingness to make risky financial decisions.
