Cognitive deficits frequently occur after stroke. Neurofeedback and biofeedback training have been shown to be a valuable treatment option in several disorders such as attention deficit hyperactivity disorder (ADHD), epilepsy or migraine. However, controlled studies demonstrating specific effects are rare, especially concerning neurological disorders. This book examines whether neurofeedback and heart rate variability (HRV) biofeedback are beneficial to people suffering from stroke with resultant memory disturbances in the rehabilitation process and whether different neurofeedback or biofeedback protocols result in specific changes of electrophysiological parameters and cognitive performance - thereby focusing on memory but also exploring attentional processes as well. Therefore two different kinds of neurofeedback training (increasing alpha power or decreasing theta power) are compared with the effects of HRV biofeedback training

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows. I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.

how good the product is
These pillows are soft, fluffy, and surprisingly supportive for the price. They’re comfortable no matter how you sleep — whether on your side, back, or stomach — and they maintain their shape well overnight without going flat. The fabric cover feels smooth and breathable, keeping things cool through the night. After a few days of fluffing and use, they settle nicely into a perfect medium firmness. They also wash and dry easily without clumping. Overall, a great‑value pillow set that offers comfort, versatility, and quality — ideal if you need an affordable yet cozy bedding refresh.
