The limited histological evidence suggests that most axons travel about 1 2mm horizontally within layer I with a few fibers also extending for distances of over 4 mm (Rockland 1994).
However, in self-pollinating crops such as barley, LD commonly extends for distances of up to 10 cM (Kraakman et al. 2004), and in some Arabidopsis populations, LD exceeds 50 cM (Nordborg et al. 2002).
The present measurements also show that foam lamellae in porous media can extend for considerable distances, greater than the length of individual pores, if oriented parallel to the overall direction of flow.
It lowers the threshold of synaptic excitability, resulting in the unmasking of normally silent interspinal synapses and the sensitization of second-order spinal neurons [ 39].Furthermore, SP can extend for long distances in the spinal cord and sensitize dorsal horn neurons at a distance from the initial input locus.
For example, a large ore body may extend for great distances underground in three dimensions, but mineralogical clues can direct sampling for the mapping effort.
Brigid is hiking with her dogs in an Arizona park — the kind where cactus is the only cover, and vistas extend for great distances — when she finds herself being targeted out in the open, atop a mesa.
The NNE sinistral faults extend for long distances ranging from 30 to 100 kms and cut one or two E-W PDZs.
For example, in plants, read-through transcription commonly refers to genes having multiple polyadenylation sites leading to transcripts that extend for variable distances into the 3' flanking region of the genes [3].
This suggests that in general, LD of longer chromosomes will extend for shorter distances and consequently such chromosomes will have lower overall LD than shorter chromosomes.
The cell bodies of peripheral sensory neurons are contained within the dorsal root ganglia, and their axons extend for large distances to innervate peripheral tissues and the central nervous system.
