retinotopic mapping ...

Aaron just sent this paper my way showing automatic segmentation for retinotopic mapping but it is done in BrainVoyager.  

I thought this would be a good time to go over the retinotopic mapping for the rest of you too.

You need to run some stimulus paradigm as in Fig 2 and then correlate the signals in the brain to when you showed the subject the stimulus. 


Then based on the anatomy in Fig 1 you deduce where the boundaries are in your individual subject (fig 6). The Brain Voyager help also shows this and does a pretty good job at showing the history of retinotopic mapping in humans starting with Sereno et al 1995.  


Have fun folks.  Looking forward to the charting of the brain from our lab subjects....  See Dr. Tutis Vilis's lecture on Primary Visual Cortex for some FLASH animation of the retinotopy.
