Axon 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 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...

متن کاملmicroRNAs in axon guidance
Brain wiring is a highly intricate process in which trillions of neuronal connections are established. Its initial phase is particularly crucial in establishing the general framework of neuronal circuits. During this early step, differentiating neurons extend axons, which reach their target by navigating through a complex environment with extreme precision. Research in the past 20 years has unr...
متن کاملTranslating Axon Guidance Cues
Recent studies suggest that local translation of mRNA within axons plays a key role in two aspects of growth cone navigation. One line of evidence implies a local synthesis of proteins that mediate growth cone collapse and turning in response to guidance cues; another indicates that growth cones possess the machinery that would allow the local synthesis of receptors for axon guidance cues.
