Cognitive dysfunction reversed in mouse model of Down syndrome
The study, published in Science Translational Medicine on November 18, revealed two important new findings about Down's syndrome in a mouse model: 1) there is evidence that synaptic terminals inv...

Now, reporting on rat experiments in the October 22 issue of Nature, a Johns Hopkins team says it has for what is believed to be the first time managed to measure and record the elusive electrical act...
Health and Medicine | Read moreStudy may explain how a well-known epilepsy and pain drug works
The finding may also point to new therapies for brain injury and neuropathic pain.The role of neurons in the brain and nervous system is well known, but astrocytes, a different type of brain c...
Life Sciences | Read moreKnow who your friends are
There are rules governing which types of connections should be established, although it remains unclear how neurons ‘know’ these rules. “Recognition seems to occur because neurons are always connected...
Life Sciences | Read moreStudy pinpoints key mechanism in brain development, raising question about use of anti-seizure drug
This discovery, based on experiments in cell culture and in mice, could advance scientists' understanding of how young children's brains develop as well as point to new approaches toward cou...

The repair of damaged nerve cells is a major problem in medicine today. A new study by researchers at the Montreal NeurologicaI Institute and Hospital (The Neuro) and McGill University, is a s...
Life Sciences | Read moreComputer Model Shows Changes in Brain Mechanisms for Cocaine Addicts
About 2 million Americans currently use cocaine for its temporary side-effects of euphoria, which have contributed to making it one of the most dangerous and addictive drugs in the country. Co...

Through the ramification of its fiber-like axon, a single neuron can send branches and thus transmit information into several target areas at the same time. In principle, neurobiologists distinguish b...
Life Sciences | Read moreGene called flower missing link in vesicle uptake in neurons
The extra membrane is then captured in a process called endocytosis and recycled to form a new vesicle to enable the next cycle of release. Most important, exocytosis must be tightly coupled with endo...
Life Sciences | Read moreRoaming receptors
Changes in the synaptic strength of neurons, effected by repeated neuronal activity, drive important behavioral processes such as learning and memory. Continuous simulation of a neuron, for example, c...
Life Sciences | Read moreSense of attraction
Many olfactory cues pervade the aquatic environment of fish. These cues stimulate various important behaviors, such as escape from predators, or attraction towards food sources or potential mates....
Life Sciences | Read moreFirst Direct Visualization of Memory Formation in the Brain
The phenomenon is called “synaptic plasticity,” and is the foundation for how we learn and remember. As we learn, the memories are stored in changes in the strength and/or number of synaptic connectio...
Life Sciences | Read moreHuntington's disease deciphered
The researchers were able to show that the mutated huntingtin gene activates a particular enzyme, called JNK3, which is expressed only in neurons and, further, to show what effect activation of that e...
Life Sciences | Read moreImpaired brain plasticity linked to Angelman syndrome learning deficits
Researchers at the University of North Carolina at Chapel Hill School of Medicine and Duke University now believe they have the answer: impaired brain plasticity."When we have experiences...
