In contrast, connecting tracts in the ventral stream are the extreme capsule (EmC) and the inferior longitudinal fasciculus, which connect the anterior part of the IFG (BA47 and to some extent BA45) with the anterior temporal gyri (aSTG and aMTG) and the posterior part of the perisylvian cortices (pSTG and pMTG; Saur et al. 2008).
For the analysis of the scans of the time course experiment with tactile stimulation all voxels that were part of the tracts connected to the left sensory thalamocortical tract were selected.
This method provides useful information about brain organization in terms of how spatially segregated brain regions are integrated globally via connecting fiber tracts (i.e., an anatomical network) to form an integrated system (for a comprehensive review, see (Bullmore and Sporns, 2009)).
In Euarthropoda, typical bilaterally arranged segmental ganglia are present, which are longitudinally connected by connectives (axonal tracts without associated neuronal cell bodies) and transversely linked by commissures.
In locusts and crayfish, the protocerebral bridge and the central body are connected via four tracts in each brain hemisphere, the W-, X-, Y-, Z-tracts, containing 5HT-ir neurites [ 66, 71].
Previous studies were also applying the notion of neighborhood as a predictor of connectivity which suggests that spatially close regions tend be connected by fiber tracts [ 10].
For example, the C3 network (Enterococcus faecalis) connected the GI tract, blood and UG tract and the C4 network (Streptococcus sanguinis) connected the oral cavity and blood.
"I am no less connected to those tracts of land that we will be forced to leave in time than any of those who speak loftily.
They consist of a series of nuclei (groups of nerve cell bodies in the central nervous system similar to a peripheral ganglion) connected by fibre tracts made up of their axons (processes that convey signals away from the cell bodies).
At the same time the two acted as agents for their father in locating tracts connected with military warrants he was purchasing.
However, syndromes certainly result from a dysfunction of an extended network of cortical and subcortical areas connected by several tracts (Damasio and Damasio 1989).
