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.

Single dose of LSD shows promise against alcoholism

Forty years ago, LSD was used in the treatment of alcoholics - with good results. Perhaps it's time to look at it again? In the 1950s, '60s and '70s, researchers in many places in the world experimented with LSD in the treatment of various disorders, including alcoholism. Not all experiments were scientifically tenable by today's standards, but some were.

Biologists identify how and where the brain processes FM sweeps

In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. For example, the pitch of someone's voice, and how it changes as they are speaking, depends on a complex series of varying frequencies. Knowing how the brain sorts out these different frequencies-which are called frequency-modulated (FM) sweeps-is believed to be essential to understanding many hearing-related behaviors, like speech.

Measuring wellbeing in Huntington’s disease

The new tool, the first Huntington’s disease-specific quality of life instrument of its kind, aims to fully capture the impact of this complex disease on the everyday life of sufferers. By using this new tool to more accurately measure the impact of Huntington’s and also any effect of therapeutic interventions, scientists will be in a better position to evaluate the usefulness of interventions on patients’ everyday quality of life to see if there is actually a practical benefit. It is hoped that in this way, this tool will lead to more effective treatments.

Cancer-based blood vessel theory questioned

Johns Hopkins scientists have published laboratory data refuting studies that suggest blood vessels that form within brain cancers are largely made up of cancer cells. The theory of cancer-based blood vessels calls into question the use and value of anticancer drugs that target these blood vessels, including bevacizumab (Avastin).

Patients with advanced Alzheimer’s benefit from drugs: Study finds

According to new developments patients with advanced Alzheimer’s disease could benefit from drug treatment to slow its progression. Scientists have shown for the first time that drugs used to slow the disease in its early stages also work when the condition is advanced, greatly extending the population who could be treated.

Heart rate lowering drug may reduce “implicit” racial prejudices: Study

It was found that volunteers given the beta-blocker, used to treat chest pains and lower heart rates, scored lower on a standard psychological test of “implicit” racist attitudes. They appeared to be less racially prejudiced at a subconscious level than another group treated with a “dummy” placebo pill.

Scientists believe that ageing can be programmed in the womb

Ageing is a complex process involving physical, psychological, and environmental factors. Scientists believe that ageing can be programmed in the womb. One example of stress during pregnancy is the administration of glucocorticoids, i. e. synthetic stress hormones to accelerate fetal lung maturation in premature labor to allow breathing after birth. Could exposure to these stress hormones have an effect on health later in life?

Surgical intervention can be life-restoring for people with intractable temporal lobe epilepsy

While the thought of any type of surgery can be disconcerting, the thought of brain surgery can be downright frightening. But for people with a particular form of epilepsy, surgical intervention can literally be life-restoring.

CB2 receptor involved in regulating impulsive behaviour

A new study lead by the Neuroscience Institute of Alicante reveals how manipulating the endocannabinoid system can modulate high levels of impulsivity. This is the main problem in psychiatric illnesses such a schizophrenia, bipolar disorder and substance abuse.

Scientists identify 2,000 important genes linked to singing

Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism.

Daylight-saving time may increase risk of heart attack

Daylight-saving time this year begins March 11, and while we all might look forward to another hour of sunshine a University of Alabama at Birmingham expert says the time change is not necessarily good for your health.

Berry fruits help the brain stay healthy in several ways

Strong scientific evidence exists that eating blueberries, blackberries, strawberries and other berry fruits has beneficial effects on the brain and may help prevent age-related memory loss and other changes, scientists report.

Loss of glutamate receptor linked to negative effects of chronic stress

Chronic stress has a more powerful effect on the brain during adolescence than in adulthood and now there's proof at the molecular level, according to findings published in Neuron by University at Buffalo researchers.

Scientists focus on genes linked with autism spectrum disorders

With the "Refrigerator Mother" notion about the cause of autism a distant and discredited memory, scientists are making remarkable progress in untangling the genetic roots of the condition, which affects millions of children and adults, according to an article in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

Some top researchers no longer think of glaucoma solely as an eye disease

A new paradigm to explain glaucoma is rapidly emerging, and it is generating brain-based treatment advances that may ultimately vanquish the disease known as the "sneak thief of sight." A review now available in Ophthalmology, the journal of the American Academy of Ophthalmology, reports that some top researchers no longer think of glaucoma solely as an eye disease.
