Mayo Clinic: Brain disorder suggests common mechanism may underlie many neurodegenerative diseases
A Mayo Clinic-led international consortium has found a mechanism that may help explain Parkinson's and other neurological disorders. view more (2009-01-12)
Molecular structure reveals how botulinum toxin attaches to nerve cells
Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food. view more (2006-12-14)
Cognitive impairment appears to be common in ALS patients
In a study of 40 patients with amyotrophic lateral sclerosis (ALS), about one-third showed evidence of cognitive impairment, but these deficits did not appear to be related to survival. view more (2006-03-14)
Penn study finds link between Parkinson's disease genes and manganese poisoning
A connection between genetic and environmental causes of Parkinson's disease has been discovered by a research team led by Aaron D. Gitler, PhD, Assistant Professor in the Department of Cell and Developmental Biology at the University of Pennsylvania School of Medicine. view more (2009-02-02)
Aston researchers first scientists in UK to explore mysteries of whole brain
The new Neurosciences Research Institute at Aston University houses one of only 10 whole head MEG scanners in the world. The equipment measures magnetic fields in the brain. view more (1999-11-17)
Understanding the Noxious cause of Lou Gehrig's disease
There is no known cure for amyotrophic lateral sclerosis (ALS), often known as Lou Gehrig disease and motor neuron disease. view more (2007-09-14)
Matrix fragments trigger fatal excitement
Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org). view more (2008-12-30)
Tracking the memory trace
Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine. view more (2005-12-05)
Neurotransmitter orexin associated with pleasure and reward pathways in the brain
Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain. view more (2005-08-26)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Molecular motor works by detecting minute changes in force
Researchers at the University of Pennsylvania School of Medicine discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I is regulated by force. The motor puts tension on cellular springs that allow vibrations to be detected within the body. view more (2008-07-10)
Drugs for Parkinson's disease may ease stroke-related disability
Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease. view more (2007-04-04)
Olfactory nerve cells expressing same receptor display a varied set of reactions
n a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities. view more (2006-02-03)
Rice University study finds possible clues to epilepsy, autism
Rice University researchers have found a potential clue to the roots of epilepsy, autism, schizophrenia and other neurological disorders. view more (2008-12-09)
Obesity and risk for death due to motor vehicle crashes
A team at the Injury Research Center of the Medical College of Wisconsin in Milwaukee has found that being obese increases male drivers' risk of dying in a car crash, as does being very slim. However, being moderately overweight might help cushion the blow. view more (2006-03-02)
Tiny but toxic: MBL researchers discover a mechanism of neurodegeneration in Alzheimer's disease
Tiny, toxic protein particles severely disrupt neurotransmission and inhibit delivery of key proteins in Alzheimer's disease, two separate studies by Marine Biological Laboratory (MBL) researchers have found. view more (2009-03-27)
Penn study on olfactory nerve cells shows why we smell better when we sniff
Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to University of Pennsylvania School of Medicine researchers in the March issue of Nature Neuroscience. view more (2007-03-14)
Neurons use chemical 'chords' to shape signaling
Researchers have discovered that neurons can use two different neurotransmitters that target the same receptor on a receiving neuron to shape the transmission of a nerve impulse. view more (2008-02-28)
Sitting and thinking, or just sitting?
Patients recovering from brain injuries such as strokes often experience difficulties carrying out two activities at the same time, according to researchers in the School of Psychology at the University of Reading. Most of us can walk, cycle or drive and carry on a conversation at the same time because the combination of motor actions is so... view more... (2004-03-19)
Alzheimer's molecule is a smart speed bump on the nerve-cell transport highway
Researchers at the University of Pennsylvania School of Medicine discovered that proteins carrying chemical cargo in nerve cells react differently when exposed to the tau protein, which plays an important role in Alzheimer's disease. view more (2008-01-18)
