BACKGROUND Variants of the apolipoprotein E (APOE) gene influence the age of onset of Alzheimer's disease. APOE may influence the presentation of other neurological diseases. We investigated the relationship between the allelic variants of apolipoprotein E and clinical presentation in motor neuron disease. METHODS 123 patients with motor neuron disease(More)
Although defects in the gene encoding the enzyme cytosolic copper/zinc superoxide dismutase (SOD1) have been reported in 20% of familial amyotrophic lateral sclerosis (ALS) patients, the etiology of the remaining familial cases and the more common sporadic form of the disease remains unknown. Recently, deletions of the neuronal apoptosis inhibitory protein(More)
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a disease with a widely varying prognosis. The majority of patients survive about 3 years, but a significant number survive for 10 years or more, leading to problems in clinical trial design. OBJECTIVE To demonstrate that simple clinical variables can be used to construct a robust predictive model for(More)
Complex cognitive operations such as memory formation and decision-making are thought to be mediated not by single, isolated brain structures but by multiple, connected brain areas. To facilitate studies on the neural communication between connected brain structures, we developed a multi-electrode microdrive for chronically recording ensembles of neurons in(More)
To meet an increasing need to examine the neurophysiological underpinnings of behavior in rats, we developed a behavioral system for studying sensory processing, attention and discrimination learning in rats while recording firing patterns of neurons in one or more brain areas of interest. Because neuronal activity is sensitive to variations in behavior(More)
