Optimal Being

Summary:  A new study unveiled a crucial role of sleep: brainwaves facilitating the cleansing of the brain by flushing out waste. This discovery not only underscores the brain’s non-dormant state during sleep but also highlights a sophisticated system where neurons’ synchronized activity powers the flow of cerebrospinal fluid, effectively removing metabolic waste and potentially neurodegenerative disease-causing toxins. This insight opens up possibilities for enhancing brain cleaning processes to combat neurological diseases and improve sleep efficiency, hinting at a future where optimized sleep could lead to better health outcomes. Key Facts: Brainwaves Propel Cleansing Fluids : During sleep, neurons coordinate to produce rhythmic waves that drive the movement of fluid through the brain, washing away waste. Potential for Disease Prevention : Understanding and enhancing this cleansing process could delay or prevent diseases like Alzheimer’s and Parkinson’s by ensuring the effective...

  Summary:  Withdrawal from psychostimulants including methamphetamines, cocaine, and nicotine, produced restructuring of brain regions and major increases in functional connectivity, a new mouse study reveals. Source:  UCSD Addictive psychostimulants, from nicotine in cigarettes to illicit drugs like  methamphetamine and cocaine, affect different regions of the brain. The same  is believed true during withdrawal; finding a common brain pathway has proved el usive.  In a new paper, publishing September 27, 2021 in the journal  eNeuro , a multi-institution team of researchers describe how withdrawal from nicotine, methamphetamine and cocaine altered the functional architecture and patterns in the brains of mice, compared to control animals.  They found that each drug produced a unique pattern of activity in the brain, but that mouse brains in withdrawal shared similar features. Perhaps more notably, the researchers said all psychostimulants shared ...

E xperienced meditators can voluntarily induce unconscious states, known as cessations, without the use of drugs. This ability, observed in Tibetan Buddhist practice, allows meditators to experience a momentary void of consciousness, followed by enhanced mental clarity. Conducted across multiple countries, the study utilized EEG spectral analysis to objectively measure brain activity during these cessation events. By correlating the meditator’s first-person experience with neuroimaging data, researchers have gained insights into the profound modulation of consciousness achievable through advanced meditation practices. Key Facts: Experienced meditators can voluntarily enter a state of cessation, momentarily losing consciousness without external aids. The study analyzed 37 cessation events in one expert meditator across 29 sessions using EEG spectral analysis. This research opens new avenues for understanding consciousness modulation through meditation. Source:  BIAL Foundation A stu...
