Trichloroethylene exposure linked to Parkinsonism

Industrial workers who worked with trichloroethylene (TCE) may face a greater risk for parkinsonism, a study by a team of University of Kentucky researchers shows.

New insight into the mechanisms underlying amnesia

Brain scans of hypnotized people that are taken as they forget and are triggered to remember have revealed neural circuitry that is key to the memory suppression and recall process.

Huntington's disease problem starts early

The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron.

Blocking parasites' communication reduces infection

One of the most common human parasites, Toxoplasma gondii, uses a hormone lifted from the plant world to decide when to increase its numbers and when to remain dormant, researchers at Washington University School of Medicine in St. Louis have found.

Stress causes whole body deterioration

Stress, to put it bluntly, is bad for you. It can kill you, in fact. A study now reveals that stress causes deterioration in everything from your gums to your heart and can make you more susceptible to everything from the common cold to cancer.

Trichloroethylene chemical - widely used in industry - is a risk factor for parkinsonism

Parkinson's disease, the most common neurodegenerative movement disorder caused by aging, can also be caused by pesticides and other neurotoxins.

Novel mechanism for long-term learning identified

Practice makes perfect - or at least that's what we're told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales - and it seems, based on the personal experience of many, to be true.

Daily alcohol use causes changes in sexual behavior

A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition.

Effects of sleep deprivation reversed

Researchers at Wake Forest University School of Medicine have shown that the effects of sleep deprivation on cognitive performance can be reversed when the naturally occurring brain peptide, orexin-A, is administered in monkeys.

Epilepsy and brain pathology linked together by the protein ADK

The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes.

Some antipsychotic drugs may be missing their mark

Drugs that treat depression, schizophrenia and other psychotic conditions and that target a particular protein on brain cells might not be triggering the most appropriate response in those cells, new research suggests.

Fish oil benefits

It's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease.

Mutations in a protein called dynein may cause inherited neuropathy

Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60.

Key enzyme keeps synapse on track

At its core, healthy neurological function hinges on the efficient passage of information between brain cells via the synapse.

Tweaking a gene may fix Fragile X syndrome

According to new research clues to Fragile X syndrome may be connected to one single human gene.

Research may bring new generation of cochlear implants

A Rutgers University team led by neuroscientist Robin Davis is opening new doors to improved hearing for the congenitally or profoundly deaf.

Depletion of antioxidant glutathione linked to Parkinson's in mice

Scientists at the Buck Institute have shown that mice suffering from a depletion of the antioxidant glutathione in dopamine-producing neurons developed nerve damage and symptoms associated with Parkinson's disease (PD) in humans.

Overexcited neurons not good for cell health

Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.

Brain malfunction explains dehydration in elderly

As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate.

Dynamic connectivity rewires neuronal circuits on the fly to sharpen senses

Researchers from the Center for the Neural Basis of Cognition (CNBC), a joint project of Carnegie Mellon University and the University of Pittsburgh, have for the first time described a mechanism called "dynamic connectivity," in which neuronal circuits are rewired “on the fly” allowing stimuli to be more keenly sensed.
