A protein found naturally in the brain may protect against Parkinson's disease

The findings also may lead to an improved understanding of a disorder called early-onset torsion dystonia.

New technique will enhance understanding of little-understood vision phenomenon

Look at something red in the room, and you'll be more likely to notice something red out of the corner of your eye, elsewhere in the room. Researchers have known that this "implicit attentional selection" is outside conscious control and that we are unaware of its functioning.

Scientists develop a way to block the signals responsible for neuropathic pain

Remember how it felt the last time you burned your finger on a hot stove? Imagine what it's like to have that burning pain in your hands or feet all the time and know there's virtually nothing you can do about it.

New clue to understanding how fatty acids work in the brain

Scientists in Cambridge have discovered that a brain protein called syntaxin enables fatty molecules, used widely in health supplements, to work in the brain to make it function properly. Lead Scientist, Dr Bazbek Davletov and his colleague Dr Colin Rickman from the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK report their findings in the journal Chemistry and Biology.

New evidence for cause of dyslexia

Addressing a persistent debate in the field of dyslexia research, scientists at the University of Wisconsin-Madison and the University of Southern California (USC) have disproved the popular theory that deficits in certain visual processes cause the spelling and reading woes commonly suffered by dyslexics.

Retina and its circuits are much more pliable than scientists previously thought

A new Oregon Health & Science University study is opening scientists' eyes to the retina's ability to rewire itself so it can adapt to different levels of ambient light.

Researchers pinpoint circuit in the brain responsible for encoding decision-making

Researchers at The Johns Hopkins University have pinpointed a circuit in the brain responsible for encoding decision-making behavior, a circuit that - if damaged - appears to prevent a person from altering that behavior when circumstances change.

Researchers have succeeded in mapping the unique patterns of neural activity produced by a wide range of odors

Revealing these distinct - but often overlapping - patterns of neural activity represents a significant step in understanding how the brain translates complex signals from odorant receptors in the nose into odor perception in the brain, the researchers said.

Comprehension of metaphors down to brain region called angular gyrus

What does it take to fathom a proverb - catch the figurative meaning of "an apple doesn't fall far from the tree"?

Protein TRPA1 essential for hearing also vital for pain perception

The same protein that "translates" sound into nerve signals to the brain and enables individuals to hear is also required for pain perception, researchers from Northwestern University Feinberg School of Medicine have found.

Activation of thermoreceptors mediates raw garlic's burning pungency

The worldwide popularity of garlic as a food ingredient and its therapeutic stature in folklore both stem in part from the distinctive pungency associated with its raw, uncooked state.

Narcotic medications can safely and effectively ease severe, chronic pain in older people

Narcotic medications can safely and effectively ease severe, chronic pain in older people with little risk that these patients will seek ever-increasing doses, UCSF medical scientists have found. Younger patients, however, are likely to want to rapidly increase their medication dose, the researchers found, posing serious potential health consequences.

Gene keeps neural cells on correct developmental path

Secrets of how the brain is wired for sex revealed

There are two brain structures that a mouse just can't do without when it comes to hooking up with the mate of its dreams--and trying to stay off the lunch menu of the neighborhood cat. These are the amygdala, which is involved in the initial response to cues that signal love or war, and the hypothalamus, which coordinates the innate reproductive or defensive behaviors triggered by these cues.

Gene keeps neural cells on correct developmental path

Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells. Then, studies showed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells.

Nurture as important as nature in developing ability for flexible self-control

Your ability to follow the rules of the road when driving on unfamiliar streets exists thanks to the way your pre-teen life experiences influenced the development of your brain. Individuals deprived of normal life experiences may lack this ability to control their behavior in novel situations, a new computer model suggests, providing insight into how nature and nurture may interact in the development of self-control.

So you thought that smell was cheese!

Researchers in the UK have found that visual words can influence the perception of smells, with pleasant words influencing olfactory brain regions to perceive an odour as pleasant, an interesting idea that might hold particular relevance for restaurateurs and advertisers.

Basic brain mechanism that causes drug-seeking behavior

In studies with rats, researchers have distinguished a burst of the brain chemical dopamine from a reward-related brain region that is associated with anticipating the delivery of cocaine. The finding, publishing in the May 19 issue of Neuron, reveals the brain signal that likely underlies the fundamental motivation to obtain such drugs, said the scientists.

Narcotic medications can safely and effectively ease severe, chronic pain in older people

Narcotic medications can safely and effectively ease severe, chronic pain in older people with little risk that these patients will seek ever-increasing doses, University of California, San Francisco (UCSF) medical scientists have found. Younger patients, however, are likely to want to rapidly increase their medication dose, the researchers found, posing serious potential health consequences.

Researchers prevent post-traumatic brain damage using experimental drug

In animal studies, researchers from Georgetown University Medical Center have shown how traumatic brain injury leads to loss of brain function - and found that an experimental drug can stop the damage and promote recovery.
