This type of long-range pathfinding activity is particularly common for neurons that control movement, as many of these neurons must establish connections with muscles that are some distance away from the brain.
Time-lapse fluorescence confocal microscopy analysis shows that endothelial cells engage in extensive pathfinding-activity during the first 72 hours, forming motile cell trains that integrate into fully interconnected anastamosed endothelial networks.
Ratnaparkhi, A., Banerjee, S. & Hasan, G. Altered levels of Gq activity modulate axonal pathfinding in Drosophila.
Future work will determine whether chronic inhibition of spinal cord activity can result in pathfinding errors as previously reported in the case of pharmacological blockage of network activity [3], [15].
Topics: neural induction and patterning cell lineage, neurogenesis, neuronal migration, axonal pathfinding, synapse elimination, the role of activity, critical periods, and the development of behavior.
Some research activities within EDI include developing pathfinding papers, institutional diagnostics, and case studies.
In developing chicks, the frequency of spontaneously occurring activity can influence motoneuron axonal pathfinding (Hanson & Landmesser, 2004, 2006).
There is also the possibility that the inhibitory effect of Kir2.1 on spontaneous motor activity could be the result of pathfinding errors involving the motoneuron axons.
Both axonal scaffolds and secreted molecular activities have been implicated in the control of TCA pathfinding.
The temporal features of the activity play an instructive role in motor neuron pathfinding [12], [13], and possibly the flexor-extensor and interlimb alternations for stepping [14].
In the growth cone, we propose that tubulin tyrosination takes part in the relative arrangement of actin and MT cytoskeletons, in the regulation of small GTPases activity, and consequently, in the proper morphogenesis, organization and pathfinding of the growth cone during development.
