Novel Photoconductive Cellular Depolarization Technology Reveals Insight Into Neuronal Growth, Guidance, and Regeneration
Date:1/30/2009

BOSTON, Jan. 30 /PRNewswire/ -- Neurosilicon's novel Photoconductive Stimulation Device (PSD) was highlighted in the recent scientific publication by Hung and Colicos titled, Astrocytic Ca2+ Waves Guide CNS Growth Cones to Remote Regions of Neuronal Activity. The article appearing in the November 2008 issue of The Public Library of Science One journal focuses on the role of neuronal activity in mediating axonal guidance. It is known that the path axons follow is important in defining neuronal connectivity in the brain. Following an injury, axons must find their way back to their proper targets or find new ones in order to achieve functional recovery. Given this, researchers have sought to better understand how axon guidance is mediated in order to potentially aid in recovery following injury.

Focusing on the affects of action potential induced depolarization, Hung and Colicos sought to extend previous findings and investigate how axonal growth cones respond to actual physiological stimulation in spatially displaced neurons. To do this' they applied photoconductive stimulation technology. One of the strengths of photoconductive stimulation is that it is optically activated and therefore non-invasive, requiring no physical cellular perturbation to elicit depolarization. Additionally, photoconductive stimulation has greater spatial specificity than extracellular field stimulation as well as greater temporal resolution than direct neurotransmitter application. Previously, photoconductive stimulation has been applied to demonstrate activity-driven new synapse formation in cultured neurons while allowing for the dynamic observation of the cellular elements within the neurons. In the current study, the application of photoconductive stimulation induced high frequency action potentials revealing that activity serves as an attractant signal for growth cones. These observations suggest a signaling pathway for activity-dependant axon guidance in which
