New findings clarify where and how the brain’s “slow waves” originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. For the first time, researchers have shown conclusively that slow waves start in the cerebral cortex, the part of the brain responsible for cognitive functions. They also found that such a wave can be set in motion by a tiny cluster of neurons.
Psychologists, psychiatrists and brainwave biofeedback clinicians all differ in their opinions about what is the best way to treat panic attacks and insomnia. For therapists, the root causes of these and other conditions are imbedded in childhood and adult traumas. Psychiatrists believe in the neuro-chemical/medication model of treatment, while neurofeedback practitioners view panic and insomnia as one of several bio-electrical imbalances within the brain that can be corrected by way of neurological training.
It seems that the challenges for adolescents in the digital age are too numerous to count. A nationwide survey on mental health for teens 13-18 showed an 8 percent having a definable anxiety disorder, with early symptoms starting around 6 years old. Sadly, of this 8 percent, only 18% received treatment by the time they turn 18.
Do you have trouble sleeping? Consider yourself not alone. Up to a 100 million Americans, and certainly millions more worldwide are struggling with chronic insomnia on a nightly basis.
Sleep researchers from Wageningen University and the National Institute for Public Health and the Environment (RIVM) are studying a link between the total amount and quality of restorative sleep and the incidence of cardiovascular disease among a group of 20.000 test subjects.
