SOUND STIMULATION CAN ALTER BRAIN WAVES AND HELP US HEAL!

-

 



Summary:

Recent research from the University of Surrey has revealed that sound stimulation can alter brain waves during REM sleep, a crucial stage for memory and cognition. This non-invasive technique, using advanced technology, could enhance memory functions by increasing the frequency of brain oscillations that slow down in dementia patients. This approach holds promise for innovative dementia treatments by targeting brain activity during sleep with minimal disruption to patients' lives.

Key Facts:

  • REM Sleep and Brain Waves: REM sleep is vital for memory and cognitive functions, but brain oscillations slow down in dementia patients. Sound stimulation during REM sleep can increase brain wave frequency.
  • Technological Innovation: Researchers employed closed-loop auditory stimulation technology, which adjusts sound stimuli in real-time to match brain wave phases. This technique demonstrated the ability to manipulate brain wave speeds.
  • Study Details: The study, conducted with 18 participants, used high-density EEG to monitor sleep and apply auditory stimuli precisely. The results showed that sound stimuli could accelerate or decelerate brain oscillations based on their phase in the REM sleep cycle.
  • Future Implications: This technique offers a potential new treatment method for dementia, providing a non-invasive, less disruptive way to enhance cognitive functions during sleep.

  • Institution: University of Surrey, in collaboration with the UK Dementia Research Institute Centre for Care Research and Technology at Imperial College London.
  • Publication: "Closed-loop auditory stimulation targeting alpha and theta oscillations during REM sleep induces phase-dependent power and frequency changes" by Ines Violante et al. in Sleep.

Dr. Valeria Jaramillo and Professor Derk-Jan Dijk from the University of Surrey emphasize that this non-invasive method could transform dementia treatment by improving brain function during REM sleep with minimal patient disruption. Dr. Ines Violante highlights the potential of this technique as a cost-effective and innovative treatment option, given the current lack of a cure for dementia.

SIMPLE SHOULDER SHRUG TARGETED MUSCLES: SHOULDER/NECK A 2011 study  involving 537 people in Denmark found that participants with work-related neck pain got significant relief by doing specific neck-strengthening exercises, including shoulder shrugs with dumbbells Start with your feet flat on the floor, in a standing position. Your feet should be shoulder-width apart. With your arms at your sides, turn your palms to face each other. If you’re doing the exercise with weights, bend down and grab them now.  Bend your knees slightly so that they line up with (not past) your toes. Keep your chin up, facing straight ahead, and your neck straight. While you inhale, bring your shoulders as high up toward your ears as you can. Do the movement slowly so that you feel the resistance of your muscles. Hold..Hold..Hold.. for 10 seconds. Lower your shoulders back down and breathe out before repeating the movement. Aim for 3 sets of 10 repetitions to start. ...
