The Science of Sleep: Dreaming, Depression, and How REM Sleep Regulates Negative Emotions

The Science of Sleep: Dreaming, Depression, and How REM Sleep Regulates Negative Emotions
by Maria Popova “Memory is never a precise duplicate of the original… it is a continuing act of creation. Dream images are the product of that creation.” For the past half-century, sleep researcher Rosalind D. Cartwright has produced some of the most compelling and influential work in the field, enlisting modern science in revising and expanding the theories of Jung and Freud about the role of sleep and dreams in our lives. In The Twenty-four Hour Mind: The Role of Sleep and Dreaming in Our Emotional Lives (public library), Cartwright offers an absorbing history of sleep research, at once revealing how far we’ve come in understanding this vital third of our lives and how much still remains outside our grasp. One particularly fascinating aspect of her research deals with dreaming as a mechanism for regulating negative emotion and the relationship between REM sleep and depression: The more severe the depression, the earlier the first REM begins.

Scientists Induced Lucid Dreaming With An Electrical Current screenshot/Inception NEW YORK (Reuters) - Nighttime dreams in which you show up at work naked, encounter an ax-wielding psychopath or experience other tribulations may become a thing of the past thanks to a discovery reported on Sunday. Applying electrical current to the brain, according to a study published online in Nature Neuroscience, induces "lucid dreaming," in which the dreamer is aware that he is dreaming and can often gain control of the ongoing plot. The findings are the first to show that inducing brain waves of a specific frequency produces lucid dreaming.

Oxytocin Enhances Pleasure of Social Interactions by Stimulating Production of “Bliss Molecule” UCI study uncovers role of oxytocin in triggering marijuana-like neurotransmitters. The hormone oxytocin, which has been associated with interpersonal bonding, may enhance the pleasure of social interactions by stimulating production of marijuana-like neurotransmitters in the brain, according to a University of California, Irvine study. The research provides the first link between oxytocin – dubbed the “love hormone” – and anandamide, which has been called the “bliss molecule” for its role in activating cannabinoid receptors in brain cells to heighten motivation and happiness. Results appear the week of Oct. 26 in the early online edition of Proceedings of the National Academy of Sciences. The researchers discovered that social contact increased production of anandamide in a brain structure called the nucleus accumbens, which triggered cannabinoid receptors there to reinforce the pleasure of socialization. When cannabinoid receptors were blocked, this reinforcement disappeared.

Anti-diabetic drug slows aging and lengthens lifespan, animal study suggests A study by Belgian doctoral researcher Wouter De Haes (KU Leuven) and colleagues provides new evidence that metformin, the world's most widely used anti-diabetic drug, slows aging and increases lifespan. In experiments reported in the journal Proceedings of the National Academy of Sciences, the researchers tease out the mechanism behind metformin's age-slowing effects: the drug causes an increase in the number of toxic oxygen molecules released in the cell and this, surprisingly, increases cell robustness and longevity in the long term. Mitochondria -- the energy factories in cells -- generate tiny electric currents to provide the body's cells with energy. Highly reactive oxygen molecules are produced as a by-product of this process.

The Relation Between the Moon and the Human Mind Every thing around us has an effect on something within us – be it our exposure to the sun’s ultraviolet radiation (UVR), looking at the morning sky, taking a walk in the forest, or swimming in the sea – nature’s beauty prompts the flow of hormones and energy in our body. But not everything that’s present in nature is fundamentally good for human beings. The Moon, romanticised by poets and artists since ages, has a series of negative effects on the human mind, scientifically and spiritually. 6 Real People With Mind-Blowing Mutant Superpowers If the insane, explosive popularity if superhero movies is any indication, we are fascinated by people who are insanely better than us at any given thing. Probably because, in real life, we're all such a bunch of incompetent boobs that we've been enslaved by blue paint, flashing lights and crying French babies. But it turns out, superpowers are real.

Right Side of Brain Can Compensate for Loss of Speech Following a Stroke After a debate that has lasted more than 130 years, researchers at Georgetown University Medical Center have found that loss of speech from a stroke in the left hemisphere of the brain can be recovered on the back, right side of the brain. This contradicts recent notions that the right hemisphere interferes with recovery. While the findings will likely not put an immediate end to the debate, they suggest a new direction in treatment.

Google signs deal to put sensors directly on your eye Google and Novartis have this morning announced an agreement to collaborate on the development of the smart contact lens that was unveiled by Google X in January. Using non-invasive sensors, the lens promises to analyze tear fluid in the eye to provide constant measurements of a person's blood glucose levels. Those can then be sent wirelessly to a mobile device and help diabetics manage their disease more easily.
