Scientists Use Sound and Light to Trigger Brain Waves in Innovative Approach to Treat Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

A recent study by MIT found a low-pitched buzz-like sound and strobe lights can be used to replicate brain waves impeded by Alzheimer’s, which improved cognitive function and helped remove plaque in mice displaying symptoms of the disease. The approach hasn’t been tested in humans yet, but if it’s possible to copy these results, it might turn into a drug-free, inexpensive way to treat this condition.

The Secret: Applying Sound and Light at the Same Frequency

The study in question follows up on a previous one, which showed that flashing light and playing sound 40 times a second into the eyes of mice with Alzheimer’s, improved their condition. According to MIT researcher Li-Huei Tsai, there is substantial reduction of amyloid protein and increased prefrontal cortex engagement when visual and auditory stimulation is combined over a period of one week. The prefrontal cortex is the part of the brain most active in cognitive functions.

Molecular ‘switch’ reverses chronic inflammation and aging

Posted by in categories: biotech/medical, life extension, neuroscience

Chronic inflammation, which results when old age, stress or environmental toxins keep the body’s immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer’s and Parkinson’s to diabetes and cancer.

Now, scientists at the University of California, Berkeley, have identified a molecular “switch” that controls the immune machinery responsible for in the body. The finding, which appears online Feb. 6 in the journal Cell Metabolism, could lead to new ways to halt or even reverse many of these age-related conditions.

“My lab is very interested in understanding the reversibility of aging,” said senior author Danica Chen, associate professor of metabolic biology, nutritional sciences and toxicology at UC Berkeley. “In the past, we showed that aged stem cells can be rejuvenated. Now, we are asking: to what extent can aging be reversed? And we are doing that by looking at physiological conditions, like inflammation and insulin resistance, that have been associated with aging-related degeneration and diseases.”

Revitalizing the Aging Brain by Activating Immune Cells

Posted by in categories: biotech/medical, life extension, neuroscience

Researchers at Albany Medical College in New York have discovered that a specific type of immune cell accumulates in older brains, and that activating these cells improves the memory of aged mice. The study, which will be published on February 5, 2020, in the Journal of Experimental Medicine (JEM), suggests that targeting these cells might reduce age-related cognitive decline and combat aging-associated neurodegenerative disease in humans.

The brain is highly susceptible to aging, with cognitive functions, such as learning and memory, gradually declining as we get older. Much of the body’s immune system also deteriorates with age, resulting in increased susceptibility to infection and higher levels of inflammation. In their new JEM study, however, a team of researchers led by Qi Yang and Kristen L. Zuloaga at Albany Medical College reveal that aging-related changes in a class of immune cell known as group 2 innate lymphoid cells (ILC2s) could allow doctors to combat the effects of aging on the brain.

ILC2s reside in specific tissues of the body and help to repair them when they are damaged. Recently, for example, ILC2s in the spinal cord were shown to promote healing after spinal cord injury. “However, whether ILC2s also reside in other parts of the central nervous system, and how they respond to aging, was unknown,” Yang says.

Researchers Link Autism To A System That Insulates Brain Wiring

Study Links Autism To ‘Insulation’ That Coats Brain Cells And Speeds Signals : Shots — Health News Brains affected by autism appear to share a problem with cells that make myelin, the insulating coating surrounding nerve fibers that controls the speed at which the fibers convey electrical signals.

Early Life Experiences Biologically and Functionally Mature the Brain

Posted by in categories: biological, education, health, neuroscience

Experiences early in life have an impact on the brain’s biological and functional development, shows a new study by a team of neuroscientists. Its findings, which centered on changes in mice and rats, reveal how learning and memory abilities may vary, depending on the nature of individual experiences in early life.

“The implications of this are many, including environmental influences on mental health, the role of education, the significance of poverty, and the impact of social settings,” says Cristina Alberini, a professor in New York University’s Center for Neural Science and the senior author of the paper, which appears in the journal Nature Communications.

“These results also offer promise for potential therapeutic interventions,” add Alberini and Benjamin Bessières, an NYU postdoctoral researcher and the paper’s co-lead author. “By identifying critical time periods for brain development, they provide an indicator of when pharmaceutical, behavioral or other type of interventions may be most beneficial.”

The scent of a rose improves learning during sleep

Posted by in categories: biotech/medical, education, health, neuroscience

Fragrance helps learning even during sleep!


Effortless learning during sleep is the dream of many people. The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg—Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) and the Faculty of Biology at the University of Freiburg have now shown that this effect can be also achieved very easily outside the lab. For the study, pupils in two school classes learned English vocabulary—with and without scent sticks during the learning period and also at night. The students remembered the vocabulary much better with a scent. The study was published in the Nature Group’s Open Access journal Scientific Reports on 27 January 2020.

“We showed that the supportive effect of fragrances works very reliably in and can be used in a targeted way,” said study leader PD Dr. Jürgen Kornmeier, head of the Perception and Cognition Research Group at the Freiburg-based IGPP and scientist at the Department of Psychiatry and Psychotherapy at the University of Freiburg—Medical Center in Germany.
