Researchers Link Autism To A System That Insulates Brain Wiring

Posted by in categories: health, neuroscience

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.

He remarks that we are at Kittyhawk as far as life extension goes. Most folks, including the Wright brothers, did not see a widespread use for aircraft at the time. Today in life extension the scientists working on it really do know what they are chasing.

My mission is to drastically improve your life by helping you break bad habits, build and keep new healthy habits to make you the best version of yourself.

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.

Mongoose’s Immunity to Cobra Venom Explained

Posted by in category: neuroscience

Why could the mongoose Rikki Tikki Tavi attack deadly snakes with impunity in Kipling’s “Jungle Book?” Because he has a uniquely mutated receptor for a brain neurotransmitter called acetylcholine, researchers at the Weizmann Institute of Science report in the Proceedings of the National Academy of Sciences.

The toxins in many snake venoms, including that of cobras, bind to the acetylcholine receptors of their victims, blocking nerve-muscle communications. Molecular biologist Sara Fuchs and her colleagues found that the acetylcholine receptor in mongooses—like that in the snakes themselves—is slightly mutated so that the venom simply bounces off the muscle cells, causing them no harm.
