Greater understanding on leptin's role in brain neurocircuitry

In investigating the complex neurocircuitry behind weight gain and glucose control, scientists have known that the hormone leptin plays a key role in the process. But within the myriad twists and turns of the brain's intricate landscape, the exact pathways that the hormone travels to exert its influence have remained a mystery.

Oligophrenin-1 signaling protein linked to mental retardation controls synapse maturation, plasticity

A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.

Genetic profiling reveals genes active in the earliest brain circuit construction

Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo.

Neuroscientists reach consensus on how the brain processes speech and language

Neuroscientists feel they are much closer to an accepted unified theory about how the brain processes speech and language, according to a scientist at Georgetown University Medical Center who first laid the concepts a decade ago and who has now published a review article confirming the theory.

Diabetes drug pioglitazone shows potential against multiple sclerosis

A drug currently FDA-approved for use in diabetes shows some protective effects in the brains of patients with relapsing remitting multiple sclerosis, researchers at the University of Illinois at Chicago College of Medicine report in a study currently available online in the Journal of Neuroimmunology.

New mouse model provides insight into human neuronal diseases

Neurosensory diseases are difficult to model in mice because their symptoms are complex and diverse. The genetic causes identified are often lethal when transferred to a mouse.

Novel method stimulates growth of new neurons in adult brain

University at Buffalo researchers have identified a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons.

Robotic therapy for cerebral palsy

Over the past few years, MIT engineers have successfully tested robotic devices to help stroke patients learn to control their arms and legs. Now, they're building on that work to help children with cerebral palsy.

Protein neuregulin 1 critical to insulating the body's wiring could also become treatment target

A new protein identified as critical to insulating the wiring that connects the brain and body could one day be a treatment target for divergent diseases, from rare ones that lower the pain threshold to cancer, Medical College of Georgia researchers say.

Decoding the human brain

'Nature' journals are synonymous with the very best in research. Earlier this year, an article by University of Leicester bioengineer Professor Rodrigo Quian Quiroga not only appeared in Nature Reviews Neuroscience, but also featured on the magazine cover. In the article, Prof. Quian Quiroga and co-author Dr. Stefano Panzeri discuss new methodologies that are enabling scientists to better understand how our brain processes information.

Discovery of neurons that 'mirror' the attention of others

Whether a monkey is looking to the left or merely watching another monkey looking that way, the same neurons in his brain are firing, according to researchers at the Duke University Medical Center.

Research brings quick, precise view of cell development and gene expression

A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.

Research shows how cocaine regulates gene expression in a crucial reward region

The study, published by Cell Press in the May 14th issue of the journal Neuron, provides exciting insight into the molecular pathways regulated by cocaine and may lead to new strategies for battling drug addiction.

Discovery of molecular defect involved in hearing loss

Scientists from The Scripps Research Institute have elucidated the action of a protein, harmonin, which is involved in the mechanics of hearing.

Meditation may increase gray matter

Push-ups, crunches, gyms, personal trainers - people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?

Discovery of eight previously unknown genes that affect blood pressure

Eight previously unknown genes that affect blood pressure were recently identified in a comprehensive international study comprising 34,433 Europeans. The findings of the study, in which Uppsala University researchers participated, are being presented in the Web edition of Nature Genetics.

Cell's split personality is a major discovery into neurological diseases

Researchers at the Université de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye.

Estrogen plays a key role in how the brain processes sounds

The findings, published in today's issue of The Journal of Neuroscience, show for the first time that a sex hormone can directly affect auditory function, and point toward the possibility that estrogen controls other types of sensory processing as well.

Potential molecular target for new schizophrenia treatments

A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation.
