Human genetic disorders of axon guidance.
This article reviews symptoms and signs of aberrant axon connectivity in humans, and summarizes major human genetic disorders that result, or have been proposed to result, from defective axon guidance. These include corpus callosum agenesis, L1 syndrome, Joubert syndrome and related disorders, horizontal gaze palsy with progressive scoliosis, Kallmann syndrome, albinism, congenital fibrosis of ...
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 کاملAxon guidance pathways served as common targets for human speech/language evolution and related disorders.
Human and several nonhuman species share the rare ability of modifying acoustic and/or syntactic features of sounds produced, i.e. vocal learning, which is the important neurobiological and behavioral substrate of human speech/language. This convergent trait was suggested to be associated with significant genomic convergence and best manifested at the ROBO-SLIT axon guidance pathway. Here we ve...
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...
