Les Fehmi PhD: Dissolving Pain
Dissolving Pain: Simple Brain-Training Exercises for Overcoming Chronic Pain by Dr. Les Fehmi and Jim Robbins
For four decades, Dr. Les Fehmi has been a leader in brainwave biofeedback (also called neurofeedback), training individuals how to balance and regulate their brainwave patterns to improve mental, emotional, and physical health.
Dissolving Pain is based on the premise that although pain is perceived to exist in a particular part of the body, pain in fact resides in the brain. Dr. Fehmi shows us that it is possible to learn to resolve pain at the brain level, using simple attention exercises. Drawing on scientific research, Dr. Fehmi explains how to quiet the pain signal in the brain, empowering readers to free themselves from many forms of pain and discomfort.
Included with the book is a 65-minute audio CD in which Dr. Fehmi guides listeners through the fundamental Dissolving Pain exercises.

Sensory Motor Rhythm
From Wikipedia
The Sensory Motor Rhythm (SMR) is brain wave rhythm. It is an oscillatory idle rhythm of synchronized electromagnetic brain activity. It appears in spindles in recordings of EEG, MEG, and ECoG over the sensorimotor cortex. For most individuals, the frequency of the SMR is in the range of 12 to 15 Hz. The feline SMR has been noted as being analogous to the human mu rhythm.
Meaning
The meaning of SMR is not fully understood. Phenomenologically, a person is producing a stronger SMR amplitude when the corresponding sensory-motor areas are idle, e.g. during states of immobility. SMR typically decrease in amplitude when the corresponding sensory or motor areas are activated, e.g. during motor tasks and even during motor imagery.
Conceptually, SMR is sometimes mixed up with alpha waves of occipital origin, the strongest source of neural signals in the EEG. One reason might be, that without appropriate spatial filtering the SMR is very difficult to detect as it is usually superimposed by the stronger occipital alpha waves.
Relevance in research
Neurofeedback
Neurofeedback training can be used to gain control over the SMR activity. Neurofeedback practitioners believe—and have produced experimental evidence to back up their claims —that this feedback enables the subject to learn the regulation of their own SMR. People with learning difficulties, ADHD, epilepsy, and autism may benefit from an increase in SMR activity via neurofeedback. In the field of Brain-Computer Interfaces (BCI), the deliberate modification of the SMR amplitude during motor imagery can be used to control external applications.
