Tectofugal Visual System Fiber Tracts Only

The file presented here is a 3D model file containing data from both diceCT and histological datasets. This file is specific to the fiber tracts utilized by the dominant tectofugal visual processing pathway. There are a number of primary tracts used by this system such as the tectothalamic tract, posterior commissure, lateral forebrain bundle, intra-isthmic tract, optic tract and many more. Additionally, we have created representations of projections between several of the tectofugal nuclei that don't necessarily use a designated fiber tract. In total we present the fiber connections between 18 unique nuclear structures occupying several distinct brain regions. This 3D model of the tectofugal fiber system is the most exhaustive to date in any avian species to our knowledge. This model is particular to the chicken but can technically represent the bulk of avian species (i.e. laterally-eyed birds) though you will likely see species specific differentiation.
