Research Shows Way for Drug Therapy for Autism

... the number, size and shape of connections between neurons in the brain," he said. In the brain, these connections between neurons are formed by small protrusions called "spines", which are spread on branches of neurons called "den...

Male Pheromones Build Brain Cells in Female Mice

...males showed around a 25 per cent in crease in new neurons in two brain regions-hippocampus and the olfactory...mouse urine can also trigger the production of new neurons inside a female's vomeronasal organ, a sense organ thought to aid pheromone detection in some mammal...

Vitamin Extends Life in Yeast, Dartmouth Medical School Researchers Find

...humans. In fact, that gene is activated in damaged neurons in order to allow NR to protect against loss of axons. The second NR pathway involves three yeast genes, two of which are found in humans. Granted that the human anti-aging apparatus is more complex, but animal studies indicate potential. Perhaps t...

UCLA Researchers Discover Link Between Parkinsons and Narcolepsy

...ents have severe damage to the same small group of neurons whose loss causes narcolepsy. The findings suggest a different clinical course of treatment for people suffering with Parkinson's that may ameliorate their sleep symptoms. In their report (currently online) in the June issue of the journal Brain, J...

Study Revises Dynamin's Role in Nerve Cell Function

... he says. Normal growth and function demand that neurons work at high capacity, so young mice without dynamin 1 eventually did die off, usually within a week or two of birth. 'These findings really change our outlook on dynamin 1, and on synaptic vesicle endocytosis in general,' Dr. Ryan says. 'It's an e...

Alzheimer's Drug may Help to Restore Speech in Stroke Patients

...alaga, Spain, says that the drug works by boosting neurons ability to communicate. The researchers wanted to find out whether Donepezil might benefit people with aphasia, a condition characterised by an inability to pronounce or comprehend speech, of which stroke is the most common cause. They conducted ...

Multiple Sclerosis Could Be Checked Through Testosterone Gel

... body. Surrounding and protecting some of these neurons is a fatty layer known as the myelin sheath, which helps neurons carry electrical signals. MS causes gradual destruction of myelin (demyelination) and transection ...

Patients Affected by Parkinsons may Be Benefited from Treadmill Exercise

...ently by allowing the remaining dopamine producing neurons to work harder and in doing so may promote stronger connections in the brain," says Jakowec. The study has been published in the Journal of Neuroscience....

Death and Disability from Brain Injury Reduced, Emory Researchers Report

...esterone is critical for the normal development of neurons in the brain and exerts protective effects on damaged brain tissue. The research team is now planning a large, multi-center, phase III clinical trial designed to test the effectiveness of progesterone in 1,000 patients with TBI. They also hope to s...

Common Pain Killer may Reduce the Risk of Brain Damage in Premature Babies

...very, very important part of the brain, from which neurons and glia cells migrate out to form all the layers of the brain," said Ballabh, an associate professor in the Department of Pediatrics, Cell Biology, and Anatomy at New York Medical College, and a neonatologist at Westchester Medical Center. The pro...

Coenzyme Q10 Does Not Improve Parkinsons Disease Symptoms

...red energy metabolism of the diseased dopaminergic neurons leads to symptomatic benefits in Parkinsons disease, the authors conclude. Future studies will need to explore the protective effects of CoQ10 at the highest effective dose (equivalent to about 2,400 milligrams per day of a standard formulation) over...

Nanomedicine Gives the Way for Nerve Cell Regeneration

...nerve cells can regrow. It is known that injured neurons in the central nervous system (CNS) do not regenerate, but it is not clear why. Adult CNS neurons may lack an intrinsic capacity for rapid regeneration, and CNS glia create an inhibitory environment...

Magnets to the rescue of Alzheimers patients

... Scientists in New York promoted the growth of new neurons in the brains of mice using a magnetic stimulus in the region associated with memory. The results were presented at the American Academy for Neuroscience conference. If proven, the technique is could help slow down the progression of the Alzheime...

$5M Gift Will Attack Lou Gehrig's Disease

...ique in ALS, which involves the death of the motor neurons that send signals to the muscles and control movement, could be a new frontier in treating the disease. Already, Marsala and Feldman have performed preliminary research in animals. The promising results from this study, which have not yet been publ...

Enriching Environment Stimulates Neurons: Hope For Fragile X Syndrome

Detecting Cold, Feeling Pain: Study Reveals Why Menthol Fresh

...ene that synthesizes the receptor, both in sensory neurons in cell culture and in mice. The cells in culture were unresponsive to cooling agents, including menthol. The genetically engineered mice did not discriminate between warm and cold surfaces until the temperature dropped to extremes. Its been known ...

Researchers Have Found Clue to How Fear Changes into Phobia

...al circuit using a drug that blocks firing only in neurons called dentate gyrus granule cells, which form part of one of the hippocampus's major neural circuits. The results show that, as well as memory, the hippocampus assesses risk. "Shutting down a specific circuit in the hippocampus abolished fear reac...

New Findings in Fragile X Mental Retardation Protein

...XF1 protein level is much lower in the hippocampal neurons involved in learning and memory than in many other cells. This may suggest that a high level of NXF1 might hinder the function of these cells. We are one of the first two labs to show that FMRP regulates gene expression at the mRNA stability level,...
