Axon guidance in the inner ear.
Statoacoustic ganglion (SAG) neurons send their peripheral processes to navigate into the inner ear sensory organs where they will ultimately become post-synaptic to mature hair cells. During early ear development, neuroblasts delaminate from a restricted region of the ventral otocyst and migrate to form the SAG. The pathfinding mechanisms employed by the processes of SAG neurons as they search...
متن کاملAxon guidance
The nervous system has the job of controlling and monitoring events throughout the whole body. But, unlike endocrine cells, which control their targets through long-range chemical cues, neurons communicate through direct cellular contacts, or synapses. As the information content of the electrical signals used by neurons is limited, much of the meaning in neural communication is conveyed by the ...
متن کاملAutoimmune Inner Ear Disease- A Clinical Viewpoint
Recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. In particular, advances have occurred in our understanding of the Autoimmune Inner Ear Disease (AIED). In this article, the authors review the different postulated theories in the pathogenesis of this disease. The clinical presentation, the available para-clinical diagnostic to...
متن کاملBiomechanics in the Inner Ear
The elongation and contraction of outer hair cells (OHCs) greatly contribute to the high sensitivity and frequency selectivity of the mammalian inner ear. The motility of OHCs is believed to be based on the conformational changes of the motor protein prestin in the plasma membrane of OHCs. In the present study, four lines of research on the inner ear were conducted. First, the mechanism by whic...
متن کاملDiffusion in axon guidance.
Axon guidance by target-derived diffusible factors plays an important role in the development of the nervous system. This paper considers the constraints imposed on this process by the mathematics of diffusion. A point source continuously producing a factor into an infinite three-dimensional volume is considered as a model for both the in vivo and in vitro situation. Basic constraints for effec...
