UCHLI in the Mammalian Nervous System
UCHL1, or Ubiquitin Carboxy Terminal Hydrolase L1, is a de-ubiquitinating enzyme (DUB) thought to be involved in ubiquitin recycling. Beyond this, its natural function is almost wholly unknown. Mice lacking this enzyme exhibit a severe and rapidly progressing neurodegenerative phenotype. Using one …

Genetic Analysis of Drosophila Stomatogastric Nervous System
The enteric nervous system (ENS) is of critical importance to an organism, as it controls the function of the gastrointestinal system. The ENS is remarkably complex, and although sculpted early in development, has to maintain plasticity throughout adulthood in the face of changing food levels, …

Cell biomechanics of the central nervous system
… In order to understand how cells of the central nervous system (CNS) respond to mechanical insults and stimuli, a combined modeling/experimental approach was adopted. A computational framework was developed to accurately model how cells deform under various macroscopically imposed loading …

Effects of sleep deprivation on autonomic nervous system
… events by increasing the sympathetic nervous system activity. The aim of the present study was to evaluate the relationship between sleep deprivation and the autonomic nervous system activity by means of heart rate variability (HRV) and blood pressure variability (BPV). All data were …

Allocation of Computational Resources in the Nervous System.
The nervous system integrates past information together with predictions about the future in order to produce rewarding actions for the organism. This dissertation focuses on the resources underlying these computations, and the task-dependent allocation of these resources. We present evidence that …

Axon-glia interactions during central nervous system myelination
Myelination drastically speeds up action potential propagation along axons, which is fundamental for the correct function of neuronal circuits. However, axon-oligodendrocyte interactions regulating the onset of myelin formation remain unclear. I sought to determine how reticulospinal axons control …

Differences in sympathetic nervous response due to gender
The sympathetic nervous system, in addition to its many roles as part of the autonomic nervous system, utilizes contact with many organs in the body to recruit them for an immediate response to danger. The multiple survival responses that the sympathetic nervous system manifests are typically known …

Regeneration and maintenance of the planarian nervous system
… regenerate all tissues, including the central nervous system and the eyes. This process depends on a population of cells in the adult, the neoblasts, that includes pluripotent stem cells. Whether the neoblast population also includes progenitors specialized for forming specific lineages has not …

Multivariate Discrimination of Emotion-Specific Autonomic Nervous System Activity
The present study investigated autonomic nervous system (ANS) patterning during experimentally manipulated emotion. Film clips previously shown to induce amusement, anger, contentment, disgust, fear, and sadness, in addition to a neutral control, were presented to 34 college-aged subjects while …

Neuronal plasticity in the enteric nervous system motor pathways
… underlying neurotransmission within the enteric nervous system are not yet known. Acetylcholine acting on nicotinic receptors mediates the majority of fast synaptic transmission between enteric neurons, however, recent studies suggest that the peristaltic motor pattern can occur during nicotinic …

Alginate-based Hydrogels for Central Nervous System Tissue Regeneration
As the central nervous system shows very little capability for self-repair following injury, regenerative medicine approaches are increasingly interested in the use of stem cells for cell replacement strategies. Biomaterials are an interesting tool to carry out this type of therapies. They allow …

Spontaneity and Precision in the Drosophila Central Nervous System
<p>Many organisms that can locomote change their navigational strategies depending upon behavioral context. During foraging or exploration, for instance, many animals navigate by interspersing straight runs with turns whose direction and frequency may originate, at least at times, from largely …

Diabetes: The Interrelationship between Vascular, Nervous Systems and Avandia
… endothelial dysfunction, autonomic and somatic nervous systems impairment in diabetic patients. These studies also evaluated the effects of rosiglitazone (Avandia) on the vascular, autonomic, and somatic nervous systems.</p> <p>Fourteen diabetic subjects and fourteen control subjects (age …

GENETIC CONTROL OF EYE AND CENTRAL NERVOUS SYSTEM DEVELOPMENT
Aniridia, a congenital ocular disorder caused by haploinsufficiency of transcription factor PAX6, is characterized by complete or partial iris hypoplasia with associated foveal hypoplasia. Brain imaging performed in patients heterozygous for PAX6 mutations often reveal absence of the brain anterior …
