The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Study reveals new role for the 'hormone of love'

Much of the body's chemistry is controlled by the brain - from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the body. In the process, they discovered a surprising new role for the 'hormone of love,' showing that it helps to direct the development of this brain structure.

Nicotine might prime the brain to enhance behavioral effects of cocaine

A landmark study in mice identifies a biological mechanism that could help explain how tobacco products could act as gateway drugs, increasing a person's future likelihood of abusing cocaine and perhaps other drugs as well, according to the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study is the first to show that nicotine might prime the brain to enhance the behavioral effects of cocaine.

Study highlights profound impact of maternal separation on infants

A woman goes into labor, and gives birth. The newborn is swaddled and placed to sleep in a nearby bassinet, or taken to the hospital nursery so that the mother can rest. Despite this common practice, new research published in Biological Psychiatry provides new evidence that separating infants from their mothers is stressful to the baby.

Cypin protein may prevent long-term brain damage after stroke

One of two proteins that regulate nerve cells and assist in overall brain function may be the key to preventing long-term damage as a result of a stroke, the leading cause of disability and third leading cause of death in the United States.

Nmnat1 protein may help prevent brain damage in babies with cerebral palsy

Scientists at Washington University School of Medicine in St. Louis have shown that a protein may help prevent the kind of brain damage that occurs in babies with cerebral palsy.

Argus II Retinal Prosthesis System successfully implanted in advanced Retinitis Pigmentosa patient

Second Sight Medical Products, Inc., the world's leading developer of retinal prostheses for the blind, announced that the first ever commercial implantation of such a prosthesis was successfully completed on Saturday, October 29th in Pisa, Italy.

Leeches shift the way they locate prey in adulthood

Many meat-eating animals have unique ways of hunting down a meal using their senses. To find a tasty treat, bats use echolocation, snakes rely on infrared vision, and owls take advantage of the concave feathers on their faces, the better to help them hear possible prey.

Study supports existence of metastable frequency-band-dependent scaffold of brain connectivity

Over the past two decades, the increased ability to analyze relationships among neural structures has provided novel insights into brain function. Most network approaches, how-ever, focus on static representations of the brain's physical or statistical connectivity.

Hospital architecture, design and sensory stimulation make rehabilitation more effective

How does the hospital environment affect our rehabilitation? New research from the University of Gothenburg, Sweden, into how the space around us affects the brain reveals that well-planned architecture, design and sensory stimulation increase patients' ability to recover both physically and mentally. Digital textiles and multisensory spaces can make rehabilitation more effective and reduce the amount of time spent in care.

Birth control shot may impair a person's memory

The birth control shot Depo Provera offers a convenient alternative for women who don't want to remember to take a daily pill. Ironically, research from Arizona State University has shown the shot actually may impair a person's memory.

Massive clotting can destroy placenta and cause miscarriages

Researchers at St. Michael's Hospital have identified a potential new cause for unexplained miscarriages in mice.

Ocrelizumab drug holds promise for multiple sclerosis

An experimental drug called Ocrelizumab has shown promise in a Phase 2 clinical trial involving 220 people with multiple sclerosis (MS), an often debilitating, chronic autoimmune disease that affects an increasing number of people in North America.

SmartTots sets agenda for research on anesthetic safety in children

A special section of the November issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS), presents new research, updates, and commentaries about possible toxic effects of anesthetics and sedatives in infants and young children. The IARS is a key partner in the SmartTots initiative, dedicated to finding scientific answers to these urgent public health concerns.

$Adiponectin linked to osteoporosis and increased risk of fractures$

Adiponectin linked to osteoporosis and increased risk of fractures

While obesity is a well-known cause of cardiovascular disease, research from the Sahlgrenska Academy at the University of Gothenburg, Sweden, has now revealed that the body's obesity hormones - adiponectin - are also linked to osteoporosis and an increased risk of fractures.

MIT develops new software to speed up MRI scans

Magnetic resonance imaging (MRI) devices can scan the inside of the body in intricate detail, allowing clinicians to spot even the earliest signs of cancer or other abnormalities. But they can be a long and uncomfortable experience for patients, requiring them to lie still in the machine for up to 45 minutes.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

New e-tool to catch youth depression before it takes hold

Australian researchers will for the first time harness e-technology to develop a customised internet program to identify and arm healthy young people most at risk of depression before the illness takes hold.

Happiness good for health: Study

A new study suggests that happiness is good for health. Epidemiologists at University College, London, reported their results Monday in the journal Proceedings of the National Academies of Science.

Restoration of dopamine levels could potentially prevent drug abuse

Portuguese researchers have discovered that rats exposed before birth to glucocorticoids not only show several brain abnormalities similar to those found in addicts, but become themselves susceptible to addiction (the glucorticoids, which are stress hormones, were used to mimic pre-natal stress).

Emotional and psychological traumas may contribute to adult IBS

The psychological and emotional traumas experienced over a lifetime--such as the death of a loved one, divorce, natural disaster, house fire or car accident, physical or mental abuse—may contribute to adult irritable bowel syndrome (IBS), according to the results of a study unveiled today at the American College of Gastroenterology's (ACG) 76th Annual Scientific meeting in Washington, DC.
