For an extensive study of radiation and radiation shielding for space settlement, including a large literature search, see http://space.alglobus.net/papers/RadiationPaper.pdf Joe, by the way, is a co-author.

NOTE: a new version of this paper including results from some major radiation studies should be out in a couple months.

Its well-known that radiation can damage neural tissue and hurt cognitive function; cancer patients with brain tumors who need radiotherapy end up with what the study authors called severe and progressive cognitive deficits. But its not clear exactly what effect space radiation has on the brain because there are different types of radiation and theyre delivered in different doses.
