What is Transcranial Photobiomodulation and How Does it Work?
Transcranial photobiomodulation (tPBM) is a non-invasive brain stimulation technique that involves the use of near-infrared light to improve brain function. This therapy is gaining popularity for its potential to treat various neurological and psychiatric disorders, including Alzheimer's disease, depression, and traumatic brain injury (TBI).
Neural Oscillations: An Overview of the Brain's Electrical Activity
Neural oscillations are the electrical activity of the brain that underlies various cognitive processes such as attention, perception, and memory. These oscillations occur at different frequencies and can be measured using electroencephalography (EEG).
How Can Transcranial Photobiomodulation Modulate Neural Oscillations?
Recent research has shown that tPBM can modulate neural oscillations and improve brain function. By targeting specific brain regions, tPBM can increase or decrease neural oscillations in those regions, leading to improved cognitive performance.
One study found that tPBM increased alpha and beta oscillations in the prefrontal cortex, resulting in improved working memory performance. Another study showed that tPBM decreased delta oscillations in the default mode network, leading to reduced symptoms of depression.
Transcranial Photobiomodulation as a Potential Therapy for Neurological and Psychiatric Disorders
As research in this field continues to expand, tPBM is becoming an increasingly promising therapy for neurological and psychiatric disorders. However, optimizing the parameters of tPBM, such as wavelength, intensity, and duration, is essential to maximize its effectiveness.
In conclusion, tPBM is a safe and effective therapy for modulating neural oscillations and improving brain function. With continued research, tPBM has the potential to revolutionize the treatment of neurological and psychiatric disorders.
