1 The neuropeptide substance P (SP) exerts an excitatory effect on sympathetic neurones by inhibiting a time- and voltage-dependent potassium current. During prolonged application of SP, the response desensitizes. The changes in kinetics of the SP…
BACKGROUND: Hyperglycemia after ischemic stroke in adults and after near-drowning in children is associated with a poor neurological outcome. Anaerobic metabolism of glucose leads to buildup of lactic acid, free radical production, mitochondrial…
Study Design, Caudal vertebrae were obtained from male and female mice from two transgenic lines expressing an erythroid-specific human growth hormone-transgene construct, and gender-matched, age-matched, nontransgenic control mice. Objective. To…
Exposure to the industrial solvent, styrene, induces locomotor and cognitive dysfunction in rats, and parkinsonian-like manifestations in man. The antipsychotic, haloperidol (HP), well known to induce striatal toxicity in man and animals, and styrene…
Case managers spend more time with clients with schizophrenia than any other professional group does in most clinical settings in the United States. Cognitive behavioral therapy (CBT) adapted for individuals with persistent psychotic symptoms,…
We studied the ontogeny of muscarinic depression in the developing rat visual cortex using carbachol (a nonhydrolyzable cholinergic agonist) application to neocortical slices obtained from four postnatal age groups: 9-10 days, 15 days, 30-40 days and…
The multiple disease etiologies that lead to neuropsychiatric disorders, such as Parkinson's and Alzheimer's disease, amyotrophic lateral sclerosis, Huntington disease, schizophrenia, depressive illness and stroke, offer significant challenges to…
Context. Women diagnosed with ovarian cancer are at risk for reduced quality of life (QOL). It is imperative to further define these declines to interpret treatment outcomes and design appropriate clinical interventions. Objectives. The primary…
Spontaneous activity is a well-known neural phenomenon that occurs throughout the brain and is essential for normal development of auditory circuits and for processing of sounds. Spontaneous activity could interfere with sound processing by reducing…
The positive chronotropic and inotropic effects of vasoactive intestinal peptide, VIP, were studied in an isolated canine right atrial preparation, Atria were removed, maintained in a bath, and perfused with Tyrode's solution. Contractile force and…
We determined if kainic acid, a neuroexcitotoxin, could be used to denervate the cell bodies of cardiopulmonary vagal sensory neurons. Kainic acid (5 mug) was injected into the nodose ganglion of five dogs. Ten to fourteen days following this…
Expression of myosin heavy chain (MHC) isoforms was studied in rat soleus (SOL) and extensor digitorum longus (EDL) muscles which regenerated in the presence or absence of innervation. Frozen sections of two 5 day denervated SOL and EDL grafts, two…
The physical arrangement of receptive fields (RFs) within neural structures is important for local computations. Nonuniform distribution of tuning within populations of neurons can influence emergent tuning properties, causing bias in local…
Patients with symptomatic L-5 nerve root compression and associated lytic spondylolisthesis are commonly treated by bilateral wide posterior decompression and concomitant fusion, often accompanied by transpedicular instrumentation. More limited…
Study Design. A description of the technique for lumbar microdecompression and a prospective study of the outcomes. Objective. To describe and analyze a technique that affords an excellent decompression while minimizing damage to surrounding tissues.…
Interbody cage devices, used to assist interbody fusion, are rapidly gaining popularity in the surgical management of chronic low back pain. This update provides a structural classification of commonly used devices and assesses them against a set of…
Combination-sensitive neurons serve as the fundamental processing unit in Sussman and colleagues' proposal for the neural representation of of stop consonants. This commentary describes recent studies in the mustached bat that show how ubiquitous and…
Background: Neuroinflammation-astrogliosis, microglial activation, and changes in cytokine signaling-is a prominent feature of neurodegenerative disorders. Glaucoma is a group of chronic neurodegenerative conditions that make up the leading cause of…
Study Design. A description of a method for standardizing the nomenclature used in reporting the size and location of lesions in the lumbar or thoracic spine is presented. Objectives. To make the reporting of findings on computed tomography or…
Activity dependent calcium entry into neurons can initiate a form of synaptic plasticity called long-term potentiation (LTP). This phenomenon is considered by many to be one possible cellular mechanism underlying learning and memory. The calcium…
Evidence from human amyotrophic lateral sclerosis (ALS) patients and ALS-linked Cu/Zn superoxide dismutase (Cu/Zn-SOD) transgenic mice bearing the mutation of glycine to alanine at position 93 (G93A) suggests that the pro-apoptotic protein prostate…
Epidemiological studies have strongly linked caffeine consumption with a reduced risk of developing Parkinson's disease (PD) in men. Interestingly, in women, this inverse association is present only in those who have not taken postmenopausal…
Glutamate and aspartate are the primary neurotransmitters of projections from motor and premotor cortices to the striatum. Release of glutamate may be modulated by dopamine receptors located on corticostriatal terminals. The present study used…
