By delivering to the brain multiple electric fields at frequencies too high to recruit neural firing, but which differ by a frequency within the dynamic range of neural firing, we can electrically stimulate neurons throughout a region where interference between the multiple fields results in a prominent electric field envelope modulated at the difference frequency.
Specify a sigma value to determine how harshly the comparison is judged (a good value is the radius of the segmented filaments).
Visualization will require a programmable GPU that supports GLSL.
Please reference their original work (JQSRT, 2011) in any publications and contact him regarding any licensing concerns.[source] Simple and robust programmable volume visualization.
This software allows the user to prototype programmable volume shaders and transfer functions written in GLSL.
Please send me an e-mail if you have any problems with the software.[project page] [source] This is a command-line tool designed to do basic data-processing for extremely large hyperspectral images.
