In these cases, such as the frontal eye field being spatially distant from the rest of the visual cortex, spatial proximity would not predict a connection.
If in addition a high spatiogenetic correlation would exist, this would indicate a consistent spatial arrangement of these groups in the sense that on the average spatially neighboring groups are genetically more similar than spatially distant groups.
The simple presence of ligand/receptor combinations does not necessarily indicate this type of mechanism, especially when the ligand and the receptor are produced in spatial sites distant from each other [ 15].
In the early 21st century specialized interferometric techniques have routinely improved spatial resolution of distant objects by factors of 10 100 over earlier surface-based observations.
Thus, Storke Ranch provided an adequately complex environment for learning, with few distant spatial referents, but was easily accessible from the UCSB campus.
Storke Ranch is closed off to surrounding neighborhoods by tall concrete fences and the two-story homes block most visual access to distant spatial referents, such as the mountains to the north.
Many processes do not even enter maps in the first place, due to distant spatial or temporal drivers, societal meaning and relevance, and transformation over time (although this is hidden in a map; Wood 2010).
Recent studies performed using 3C (chromosome conformation capture -based methods, FISH (fluorescapture -basedhybridization) coupled with confocal methodsopy, and other experimental approaches have revealed that the spatial interactions oFISHstant genomic elements within a fluorescenceosome are specinic and functionally relevant.
Registration errors occurring during the normalization of individual scans is a common criticism of the VBM method [24], as voxels close on a spatial scale, but distant in term of cerebral architecture (for instance, two different white matter bundles spreading in one part and another of a sulcus) could be merged during the analysis.
Spatial proximity between distant chromosomal loci has been associated with chromosomal rearrangements, as observed between RET and the H4 genes located 30 megabases (Mb) apart on chromosome 10, involved in RET gene fusions in papillary thyroid carcinoma [ 152].
