Electron microscope reveals minute morphology of dendritic trees

Neurons in the brain play a role as an electric wire conveying an electrical signal. Because this electric wire is connected with various joints, various brain functions can occur. A neuron which has dendritic trees on it, receives the signals with many synapses located on those dendritic trees, and carries out functions by combining the received signals.

UC Berkeley scientists offer treatment hope for patients with tinnitus

Neuroscientists at the University of California, Berkeley, are offering hope to the 10 percent of the population who suffer from tinnitus - a constant, often high-pitched ringing or buzzing in the ears that can be annoying and even maddening, and has no cure.

Tics are not a rare or uncommon disorder

Experts have confirmed it: tics are not a rare or uncommon disorder. It is the second study to be conducted in Spain to date, and the first of great importance, revealing that the prevalence of these motor disorders in the child population is 16.86%. The incidence is greater in boys than girls, and they tend to disappear or reduce with age.

Excitation and inhibition remain balanced, even when the brain undergoes reorganization

Every second, the brain's nerve cells exchange many billions of synaptic impulses. Two kinds of synapses ensure that this flow of data is regulated: Excitatory synapses relay information from one cell to the next, while inhibitory synapses restrict the flow of information.

Human brain places more value on winning in a social setting

A new USC study explains why people take stupid chances when all of their friends are watching that they would never take by themselves. According to the study, the human brain places more value on winning in a social setting than it does on winning when you're alone.

Scientists discover two opposing neuronal regulatory circuits for generation, elimination of fear

Emotional balance is regulated by molecular factors behind stress response. When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety.

Study: K-complexes control effects of noise on sleep

During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.

Novel analysis of MRI scans reveals distinct features of autistic brain

Researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital have used a novel method for analyzing brain-scan data to distinguish children with autism from typically developing children.

New medicines to target LPA receptors may prevent serious developmental brain diseases

Examining brain damage that occurs when fetuses in the womb are deprived of oxygen, researchers at The Scripps Research Institute have discovered that damage does not occur randomly but is linked to the specific action of a naturally occurring fatty molecule called LPA, acting through a receptor that transfers information into young brain cells.

Age-related declines in hearing may accelerate brain atrophy

A new study by researchers from the Perelman School of Medicine at the University of Pennsylvania shows that declines in hearing ability may accelerate gray mater atrophy in auditory areas of the brain and increase the listening effort necessary for older adults to successfully comprehend speech.

New study pinpoints areas of the brain used exclusively for language

New research from MIT suggests that there are parts of our brain dedicated to language and only language, a finding that marks a major advance in the search for brain regions specialized for sophisticated mental functions.

Latest Perspectives in General Physiology series examines sensory mechanisms

The latest Perspectives in General Physiology series examines the mechanisms of visual, aural, olfactory, and tactile processes that inform us about the environment. The series appears in the September 2011 issue of the Journal of General Physiology.

Research: Brains of older adults are wiser than younger ones

The brains of older people are not slower but rather wiser than young brains, which allows older adults to achieve an equivalent level of performance, according research undertaken at the University Geriatrics Institute of Montreal by Dr. Oury Monchi and Dr. Ruben Martins of the Univeristy of Montreal.

New mouse brain atlas provides insight into how genes work in cerebral cortex

A new atlas of gene expression in the mouse brain provides insight into how genes work in the outer part of the brain called the cerebral cortex. In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language.

USPTO issues Notice of Allowance for Cortex AMPAKINE molecules to treat respiratory depression

Cortex Pharmaceuticals, Inc. announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for a patent that protects the use of AMPAKINE molecules for the treatment or prevention of respiratory depression.

Scientists identify brain-circuit defect that triggers absence seizures

Researchers at the Stanford University School of Medicine have identified a brain-circuit defect that triggers absence seizures, the most common form of childhood epilepsy.

Risk of depression in formerly depressed people

Depression is increasingly recognized as an illness that strikes repeatedly over the lifespan, creating cycles of relapse and recovery. This sobering knowledge has prompted researchers to search for markers of relapse risk in people who have recovered from depression. A new paper published in Elsevier's Biological Psychiatry suggests that when formerly depressed people experience mild states of sadness, the nature of their brains' response can predict whether or not they will become depressed again.

Cortex second quarter net loss decreases to $356,000

Cortex Pharmaceuticals, Inc. reported a net loss of approximately $356,000, or $0.00 per share, for the quarter ended June 30, 2011, compared with a net loss of approximately $2,454,000, or $0.04 per share, for the corresponding prior year period, with the difference reflecting revenues in the current year period from the Company's option agreement with Servier, France's largest privately held pharmaceutical company.

Positive link between fish oil supplements and cognitive function

Researchers at Rhode Island Hospital's Alzheimer's Disease and Memory Disorders Center have found positive associations between fish oil supplements and cognitive functioning as well as differences in brain structure between users and non-users of fish oil supplements.

Study: Eye contact seems to act as an invitation for mimicry

Imitation may be the sincerest form of flattery but how do our brains decide when and who we should copy? Researchers from The University of Nottingham have found that the key may lie in an unspoken invitation communicated through eye contact.
