Paper Abstract

To study possible preferential light penetration along the axis of white matter tracts in bovine brain, red laser light was interstitially delivered and detected by isotropic fiber tips, both parallel and perpendicular to the nerve fibers. A significant difference of 0.11 mm-1 was found between the mean effective attenuation coefficients of both directions (p < 0.02).
