Introduction to cytoskeletal dynamics and pathfinding of neuronal growth cones.
S ince the discovery of the neuron as the cellular component of the nervous system more than 100 years ago, scientists have attempted to unlock the mysteries of how the nervous system develops its myriad of synaptic connections. Santiago Ramón y Cajal was the first to identify many of the complex types of neurons that exist in the central and peripheral nervous systems (Ramón y Cajal 1897,1899,...
متن کاملNeuronal pathfinding is abnormal in mice lacking the neuronal growth cone protein GAP-43
GAP-43 has been termed a "growth" or "plasticity" protein because it is expressed at high levels in neuronal growth cones during development and during axonal regeneration. By homologous recombination, we generated mice lacking GAP-43. The mice die in the early postnatal period. GAP-43-deficient retinal axons remain trapped in the chiasm for 6 days, unable to navigate past this midline decision...
متن کاملEmotional Pathfinding
This paper presents a study of the influence of emotions on the behaviour of an intelligent pathfinding agent. A model of pathfinding is proposed that takes into account the emotional state of the agent. Results show that blindly following the most urgent emotion can lead to degenerate behaviour, and that cross-exclusion can be used to effectively moderate emotional influences. Applications of ...
متن کاملCooperative Pathfinding
Cooperative Pathfinding is a multi-agent path planning problem where agents must find non-colliding routes to separate destinations, given full information about the routes of other agents. This paper presents three new algorithms for efficiently solving this problem, suitable for use in Real-Time Strategy games and other real-time environments. The algorithms are decoupled approaches that brea...
متن کاملPathfinding by neuronal growth cones in grasshopper embryos. II. Selective fasciculation onto specific axonal pathways.
In the previous paper (Raper, J.A., M. Bastiani, and C.S. Goodman (1983) J. Neurosci. 3:20-30) we showed that the growth cones of two sibling neurons, the G and C cells, follow the same route in the developing grasshopper neuropil until they reach a stereotypic choice point. Here their growth cones diverge from each other as G turns and extends anteriorly and C turns and extends posteriorly. In...
