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.

Nanocomposite brain probe induces less scarring after implantation

A hard probe inserted in the cerebral cortex of a rat model turns nearly as pliable as the surrounding gray matter in minutes, and induces less of the tough scarring that walls off hard probes that do not change, researchers at Case Western Reserve University have found.

Brain and cooperation

When Nancy Grace and her partner danced a lively rumba to Spandau Ballet's 1980's hit, "True," on a recent "Dancing with the Stars," more was going on in the legal commentator's brain than worry over a possible wardrobe malfunction. Deep in Grace's cortex, millions of neurons were hard at work doing what they apparently had been built to do: act and react to partner Tristan MacManus's movements to create a pas de deux that had the dancers functioning together (for the most part) like a well-oiled machine.

Study reveals how default-mode network neurones interfere with our ability to pay attention

A study carried out by a team at the Centre de Recherche en Neurosciences de Lyon has just revealed how this network interferes with our ability to pay attention, by assessing the activity of the human brain's default-mode network neurones on a millisecond scale for the first time ever, in collaboration with Philippe Kahane's epilepsy department in Grenoble.

Cerebellum contributes to creation of cognitive map in the hippocampus

The cerebellum is far more intensively involved in helping us navigate than previously thought. To move and learn effectively in spatial environments our brain, and particularly our hippocampus, creates a "cognitive" map of the environment. The cerebellum contributes to the creation of this map through altering the chemical communication between its neurones. If this ability is inactivated, the brain is no longer able to to create an effective spatial representation and thus navigation in an environment becomes impaired.

Impulsive men have lower levels of GABA in dorsolateral prefrontal cortex

Impulsive individuals tend to display aggressive behavior and have challenges ranging from drug and alcohol abuse, to problem gambling and difficult relationships. They are less able to adapt to different social situations. Impulsivity is also a common feature of psychiatric disorders.

Einstein scientists receive two NCI grants to study cancer metastasis

The National Cancer Institute (NCI) has awarded Albert Einstein College of Medicine of Yeshiva University two grants totaling $8 million to study the microenvironments that drive the spread of cancer from the primary tumor to other parts of the body in the process known as metastasis.

University of Nebraska to honor UT Dallas director for communication research

The University of Nebraska will honor Dr. Thomas Campbell, executive director of the UT Dallas Callier Center for Communication Disorders, for a long record of research and academic achievement at the university's annual Alumni Masters Week.

Ten rules for good sleep

Generally, it is always easier to stay up an hour later than to go to sleep an hour earlier, so most people have relatively little problem setting the clocks back in the Fall. This is because our basic circadian rhythm (the "body clock") actually seems to be programmed for a longer than 24 hour day: it runs a little slow.

Amphetamine use in adolescence can affect brain chemistry and behaviour

Amphetamine use in adolescence can cause neurobiological imbalances and increase risk-taking behaviour, and these effects can persist into adulthood, even when subjects are drug free. These are the conclusions of a new study using animal models conducted by McGill University Health Centre (MUHC) researcher Dr. Gabriella Gobbi and her colleagues.

Scientists identify mechanism by which GBM promotes neurodegeneration

Researchers from Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine have discovered a mechanism by which glioblastoma multiforme (GBM), the most common form of brain cancer, promotes the loss of function or death of neurons, a process known as neurodegeneration.

Scientists discover neurons responsible for light-induced arousal response

Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

Edwards Life Sciences heart valve approved in the US

The U.S. Food and Drug Administration (FDA) this Wednesday approved the sale of Edwards Life Sciences Corp's Sapien heart valve for patients deemed too sick to have open-heart surgery.

The brain and the heart may not be so different after all

What do heart disease and dementia have in common? Perhaps more than meets the eye, according to researchers at the University of Rochester Medical Center.

Study reveals what causes lysosome to overflow in Batten disease

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood.

Pupil can constrict without any input from brain

You've seen it on television: A doctor shines a bright light into an unconscious patient's eye to check for brain death. If the pupil constricts, the brain is OK, because in mammals, the brain controls the pupil. Or does it? Now, researchers at Johns Hopkins have discovered that in most mammals, in fact in most vertebrates, the pupil can constrict without any input from the brain.

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.
