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.

Researchers observe brain cell development in real time

For the first time anywhere, a researcher at the Hebrew University of Jerusalem has succeeded in observing in vivo the generation of neurons in the brain of a mammal.

Link between mild infection and hypoxic apnoea

Apnoea and sudden infant death syndrome (SIDS) represent major medical concerns in the neonatal population, and infection may play a crucial role in their pathogenesis.

Study challenges conventional wisdom about cancer cells

A team of St. Jude investigators challenged conventional wisdom about the eye cancer retinoblastoma by using a mouse model that allowed them to study the tumors as they develop and grow.

Tracing the path of depression

David Nutt, Professor of Psychopharmacology, said: "The development of one of these radioactive tracers to enable the study of noradrenaline and its related processes in those suffering depression is critical to our proper understanding of this disease.

Some cancers linked to extremely low frequency electromagnetic fields

The researchers opted to study this group, because railway workers in Switzerland tend to change jobs infrequently and are exposed to much higher levels of electromagnetic field radiation than the general population.

New adult brain cells may be central to lifelong learning

The steady formation of new brain cells in adults may represent more than merely a patching up of aging brains, a new study has shown.

Immune antibodies penetrate neurons to clear Alzheimer's-linked amyloid

Researchers at Weill Cornell Medical College have gotten much closer to understanding how immune-based therapies can treat Alzheimer's disease -- by studying how antibodies go inside brain cells to reduce levels of Alzheimer's-linked amyloid peptides that form plaques between neurons.

Visual short-term memory capacity drops following sleep deprivation

When an air traffic controller at the end of a double shift forgets the location of an aircraft that had recently appeared on his screen, it may be that he did not properly take in the visual information.

Check and balance for neuron activity provides insight into schizophrenia, seizures

Two genes important for human development and implicated in cancer and schizophrenia also help keep a healthy balance between excitation and inhibition of brain cells, researchers say.

New adult nerves have a deeper role than simply replacing dead ones

You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child.

Pure oxygen harms the brain

A paramedic or doctor plops a mask over the face of a person struggling to breathe and begins dispensing pure oxygen.

More evidence found indicating potassium channels play a critical role in sleep

A gene that controls the flow of potassium into cells is required to maintain normal sleep in fruit flies, according to researchers at the University of Wisconsin School of Medicine and Public Health (SMPH).

Veterans with extreme mixed handedness and high combat exposure five times more likely to have PTSD

A recent study conducted by investigators with the Geisinger Center for Health Research shows a clear link between combat veterans' use of both hands for common tasks and the likelihood that they will experience post-traumatic stress disorder (PTSD).

Ramelteon does not impair balance, mobility or memory performance in older adults with insomnia

A new study presented today showed that ramelteon did not impair middle-of-the-night balance, mobility or memory performance in older adults with insomnia, relative to placebo.

New patented method for transporting medicine across the blood-brain barrier

Researchers at the Blanchette Rockefeller Neurosciences Institute have patented a new way of safely transporting medicine across the blood-brain barrier.

Yoga shows promise in improving symptoms associated with depression, anxiety and epilepsy

Researchers at Boston University School of Medicine (BUSM) and McLean Hospital have found that practicing yoga may elevate brain gamma-aminobutyric (GABA) levels, the brain's primary inhibitory neurotransmitter.
