For a more thorough introduction and explanation of the module please see our [documentation](http://retinotopic-mapping.readthedocs.io/).
The retinotopic mapping package is a self-contained module for performing automated segmentation of the mouse visual cortex. The experimental setup and analysis routine was modified from Garrett et al. 2014 (1), and closely follows the protocols and procedures documented in Juavinett et al. 2016 (2).
The code base contains several stimulus routines which are highly customizable and designed to give the user significant flexibility and control in creative experimental design. There are two distinct but connected aspects to the package:
1. an online experimental component comprised of the MonitorSetup, StimulusRoutines, and DisplayStimulus modules
2. an offline automated analysis component provided by the RetinotopicMapping module
The analysis takes visual altitude and azimuth maps of mouse cortex as inputs, calculates the visual sign of each pixel and auto-segments the cortical surface into primary visual cortex and multiple higher visual cortices. Ideally, the visual altitude and azimuth maps can be generated by fourier analysis of population cortical responses to periodic sweeping checker board visual stimuli (3, 4).
The package also provides some useful plotting functions to visualize the results.
Please check the jupyter notebook in the ‘examples’ folder for a documented that takes an experimental data set generated from the StimulusRoutine.py module and then performs an automated visual segmentation of the mouse cortex using the Retinotopic.py module
