Cranial Electro Therapy
stimulation (CES) is a neuromodulation tool used for treating several clinical disorders, including insomnia, anxiety, and depression.

More recently, a limited number of studies have examined CES for altering affect, physiology, and behavior

Theta-burst stimulation (TBS) is a non-invasive brain stimulation technique that delivers rhythmic electrical pulses in a specific frequency range (3-8 Hz) to mimic natural brain rhythms, potentially modulating brain activity and influencing cognitive processes or disease states.
It's a form of repetitive transcranial magnetic stimulation (rTMS) that uses bursts of 3 pulses at a high frequency (50 Hz) repeated every 200 ms, creating a 5 Hz rhythm
