If indeed suboptimal temperatures do restrict the probability of establishment, projections of a warmer climates may have important and non-linear implications for RVFV tranon-linear implications
A number of observations indicate that axon laterality at the midline and the establishment of projection patterns and eye-specific segregation at the visual targets are independent events.
We discuss the roles of the Eph/ephrin system in the establishment of retinotopic projections onto the tectum/colliculus, the most detailed studied model of topographic mapping.
The Eph receptor tyrosine kinases and their ligands are proteins that regulate axon guidance and have been shown to contribute to the establishment of topographic projections in several areas of the nervous system.
EphB receptor signals play important roles in axonal pathfinding, establishment of topographic projections during development [13], morphological alteration of filopodia to mature-shaped spines, and clustering with the NMDAR [14].
In later-born adult-specific α'/β' and α/β neurons, unf played a critical role in initial neurite extension; in contrast, for early-born γ neurons, unf was largely dispensable to the establishment of larval projections, but absolutely required for their re-elaboration of axons during early metamorphosis.
Neurotrophin-3 (Ntf3) and brain derived neurotrophic factor (Bdnf) are critical for sensory neuron survival and establishment of neuronal projections to sensory epithelia in the embryonic inner ear, but their postnatal functions remain poorly understood.
DOI: http://dx.doi.org/10.7554/eLife.03564.002 The trophic factors, neurotrophin-3 (Ntf3) and brain-derived neurotrophic factor (Bbnf) play critical roles in the embryonic inner ear, contributing to the survival of cochlear and vestibular sensory neurons and to the establishment of their projections into the respective sensory epithelia (Fritzsch et al., 2004; Ramekers et al., 2012).
Perhaps, these decussating fibers are not corticospinal axons but pioneer fibers in the CST serving as scaffolds or temporary targets for the developing corticospinal axons, in the same way as the establishment of subcortical projections is dependent on the guidance of pioneer axons from SP cells projecting toward the internal capsule (McConnell et al. 1989, 1994; Kim et al. 1991).
A recent breakthrough in the numerical treatment of the CME was the establishment of the finite state projection (FSP) method by Munsky and Khammash [ 3].
