New method found showing how nerve cells can selectively filter and transfer signals

Scientists from Gvttingen and Bochum find evidence for a new mechanism, with which our nerve cells are able to filter signals and transfer them selectively.

Visual word forming area (VWFA) of the cortex demonstrated to have an effect on word recognition

Humans have an uncanny ability to skim through text, instantly recognizing words by their shape--even though writing developed only about 6000 years ago--long after humans evolved. Thus, neuroscientists have hotly debated whether an area of the cortex called the Visual Word Form Area (VWFA) is truly a specific and necessary area for recognizing words.

Human brain observed to shut down 'self'

Everybody has experienced a sense of "losing oneself" in an activity--whether a movie, sport, sex, or meditation. Now, researchers have caught the brain in the act of losing "self" as it shuts down introspection during a demanding sensory task. New findings show that self-related function actually shuts down during such intense sensory tasks.

New theory on how the brain detects motion

Researchers at the Salk Institute for Biological Studies have discovered a neural circuit that is likely to play an important role in the visual perception of moving objects. Their finding, published in the April issue of the journal Neuron, forces neurobiologists to rethink the neural pathways that our brain relies on to detect motion.

Human brain simultaneously communicates in both analog and digital modes

A new study shows that brain cells use a mix of analog and digital coding at the same time to communicate efficiently.

Prefrontal cortex in the brain damaged by both alcoholism and chronic smoking

Alcoholism is commonly associated with chronic smoking, and both alcohol and nicotine are believed to act on the same brain region. Research builds upon previous research that identified four potential alcohol-sensitive genes in the prefrontal cortex, finding that smoking also influences the expression of these genes.

Study shows drugs work differently in the brains of men and women

A Johns Hopkins discovery could lead to tailored treatments for drug abuse and neurological diseases after providing what is believed to be the first evidence in people that amphetamines have a greater effect on men's brains than women's.

Yale researchers show how smell works within the brain

Yale scientists have systematically plotted the responses of the entire Drosophila (fruit fly) olfactory system, providing the first multi-dimensional map of the range of odorants sensed and the regions of the brain that are stimulated.

Research sheds light on eating disorders, compulsive gambling and drug abuse

Researchers at Harvard Medical School (HMS) report in the April 23 issue of Nature that they have identified neurons that encode the values that subjects assign to different items. The activity of these neurons might facilitate the process of decision-making that occurs when someone chooses between different goods.

Scientists gain greater understanding of how embryos differentiate left from right

Researchers at the Forsyth Institute have discovered a new mechanism responsible for early left/right patterning, the process by which organs locate themselves on the left or right side of the body.

New research shows specific mechanisms may not exist for facial recognition

New research from Georgetown University Medical Center suggests that the brain may not have developed a specific ability for "understanding faces" but instead uses the same kind of pattern recognition techniques to distinguish between people as it uses to search for differences between other groups of objects, such as plants, animals and cars.

Promising treatment for Huntington's disease soon to be tested clinically

At the Institut Curie, CNRS and Inserm researchers have shown that cysteamine, which is already used to treat a rare disease called cystinosis, prevents the death of neurons in Huntington's disease. Like Alzheimer's and Parkinson's, Huntington's disease, is characterized by the abnormal death of neurons.

Researchers identify novel agent that protects neurons involved in Parkinson's disease from being destroyed by rotenone

Researchers at the University at Buffalo affiliated with the New York State Center of Excellence in Bioinformatics and Life Sciences have identified a novel agent that can protect neurons involved in Parkinson's disease from being destroyed by the pesticide rotenone.

Ketogenic diet may prevent the progression of amyotrophic lateral sclerosis

A recent study directed by the Mount Sinai School of Medicine suggests a ketogenic- high caloric diet may prevent the progression of Amyotrophic Lateral Sclerosis (ALS).

Johns Hopkins researchers discover gene that reduces retinal degeneration in fruit flies

Johns Hopkins researchers have discovered a gene in fruit flies that helps certain specialized neurons respond more quickly to bright light.

Sticky proteins for neuro-chip chat

EU-funded researchers have taken the firsts steps towards future technologies combining silicon circuits and the nervous systems of mammals. Applications could include advanced drug screening and, perhaps one day, implants to help combat neurological disorders.
