Project Title - Retinotopic maps in MNI space

Much of the visual cortex is organized into visual field maps: nearby neurons have receptive fields at nearby locations in the image. These maps are usually identified in individual subjects. The precise location of each map may be different in different brains. For this project, we asked how the quality of the maps would compare using (a) standard retinoptic methods on individual brains or (b) group-averaged brains projected into MNI space.

Background

Retinotopic maps

You can use subsections if you like. Below is an example of a retinotopic map. Or, to be precise, below will be an example of a retinotopic map once the image is uploaded. To add an image, simply put text like this inside double brackets 'MyFile.jpg | My figure caption'. When you save this text and click on the link, the wiki will ask you for the figure.

Below is another example of a reinotopic map in a different subject.

Methods

We first found a really big magnet.
