This method has worked well in animals and humans. It's especially good at reaching the hippocampus. Studies show it can help with brain problems like Alzheimer's.

Flicker also changes how our immune system talks to our brain. This could help with many health issues. It's a powerful tool for scientists to study and treat brain problems.

Key Takeaways

• Rhythmic neural activity is crucial for coordinating brain regions and functions, but is often impaired in neurological and psychiatric conditions.
• Noninvasive flicker stimulation has emerged as a novel approach to modulate neural activity in both deep and superficial brain regions.
• Flicker stimulation has demonstrated efficacy in targeting the hippocampus and addressing impairments in Alzheimer's disease models.
• The technique has also shown promise in treating a range of other conditions, including cerebral ischemia and circadian rhythm disorders.
• The versatility and therapeutic potential of flicker stimulation make it a valuable tool for researchers to explore the impact of rhythmic neural activity on brain function and clinical applications.

Introduction to Brainwave Stimulation

Neural oscillations are rhythmic brain activities studied for their role in processing senses and thoughts. These brain waves, categorized by frequency, are linked to different mental states and functions.

What are Brain Oscillations?

The different types of brain rhythms include:

• Gamma frequencies (40-100+ Hz), linked to higher cognitive functions like consciousness, attention, learning, and memory.
• Beta frequencies (13-40 Hz), show normal waking alertness and stress or anxiety.
• Alpha frequencies (8-13 Hz), represent a relaxed state of focus and peak performance.
• Theta frequencies (4-8 Hz), show deep relaxation and focus, aiding in meditation and creativity.
• Delta frequencies (0.5-3 Hz), mark deep sleep and mental and physical regeneration.

Therapeutic Potential of Driving Brain Rhythms

Research has found neural frequency deficits in diseases like Alzheimer's disease. Studies show that boosting gamma-frequency oscillations can help. This is done through noninvasive rhythmic sensory stimulation, like lights and sounds at 40 Hz.

This method has been shown to reduce Alzheimer's symptoms, attract immune cells, and enhance memory in mice. It shows the promise of using noninvasive techniques to treat diseases by adjusting brain waves.

Noninvasive Deep Brain Modulation

Many studies have found odd brain rhythms in various diseases. But, we couldn't easily target deep brain areas without surgery. So, scientists came up with a way to use sensory stimulation to change brain rhythms. This method works well in animals and humans, even in hard-to-reach areas like the hippocampus.

Neurological diseases affect about 30% of the world's health problems. This shows how big of an issue brain disorders are. Tools like transcranial magnetic and electrical stimulation have helped in many studies. Also, deep brain stimulation has helped with Parkinson's and obsessive-compulsive disorder.

New methods like temporal interference (TI) stimulation aim to stimulate deep brain areas without surgery. Studies on humans have shown it works for the cortex. But, it wasn't clear if it could reach deeper areas until now.

Computers and real brain measurements showed TI stimulation can reach the hippocampus. This is a big deal. It means we might be able to treat more diseases without surgery.

Studies on healthy people showed TI stimulation can change the hippocampus and improve memory. This is exciting. It means we might be able to use non-invasive brain stimulation, deep brain stimulation, and therapeutic neuromodulation to help many conditions.
