Article Abstract

In this paper we provide, for the first time to our knowledge, the effective orientation of the SHG source in cultured cortical neuronal processes in vitro. This is done by the use of the polarization sensitive second harmonic generation (PSHG) imaging microscopy technique. By performing a pixel-level resolution analysis we found that the SHG dipole source has a distribution of angles centered at thetae =33.96 degrees , with a bandwidth of Deltathetae = 12.85 degrees . This orientation can be related with the molecular geometry of the tubulin heterodimmer contained in microtubules.
